The State Fund for Transport Infrastructure

Grants for New technology projects

Introductory word from the Minister of Transport The implementation of the new technologies is an undisputable way to increase the transport infrastructure construction efficiency. One of the important tasks in this matter is the ability to motivate the contracting authorities to require the use of these technologies during construction.

New Technology Projects should be fully applicable in the preparation and designing phase of the repair works and the construction of transport infrastructure, which results in savings of the financial costs and prolongation of repair and maintenance cycle.

The implementation of the new technologies also carries a risk, or more precisely. ‘the fear of non-tested matter. The State Fund for Transport Infrastructure commenced the funding of these projects in 2012.

In relation to the development and subsequent application of the new technologies in practise, there is a natural need - an obligation to create clear and comprehensible regulations for their application, therefore preparation of regulations are eligible for grants as well.

The main purpose of the projects is the implementation of innovative, technologically improved procedures on the roads, motorways, important waterways, state and regional railways owned by the state or regions. The projects are focused mostly on ecological solutions, higher quality, and low energy consumption of material processing, the construction of noise-proof equipment, and the use of modern projecting methods in buildings and constructions with the help of 3D options.

The project for verifying the features of ‚silent road surface’ on the roads III/32224, II/324 Pardubice

A great deal of support provided for the implementation of the intelligent transport systems for the control of traffic on transport infrastructure, which is, due growing density of traffic, a very relevant topic nowadays.

Since 2012, the funding of the new technologies has reached the amount of 389 129 000 CZK and has supported 108 individual projects Finally, I would like to give my thanks to all project submitters for their effort to implement new technology projects in the Czech Republic, and also to all employees of the State Fond for Transport Infrastructure and the Ministry of Transport for the implementation of the program.

This project included the first laying of low temperature asphalt mixture (NTAS) with high share of Rmaterial in two sections, i.e. II/235 Terešovská Huť – Terešov and II/233 Prašný Újezd. The main goal of the implemented sections is to verify the option of production and laying of asphalt mixtures with the application of foamed asphalt and higher level of R-material in the resulting asphalt mixture. The technology of foamed asphalt was tested in the loading layers with asphalt binding agent of gradation 70/100 and with two levels of dosed amount of R-material, specifically with 50% and 75% weight in the final mixture. The carpet layers included the asphalt mixtures type ACO 11 + with binding agent 50/70 in variants 20% and 40% R-material, i.e. rejuvenator Storbit or without its application.

.UDORYLFH

The mixture was produced in the mixing plant type TBA 160/240-U by Benninghoven. This plant is equipped with parallel drying drum for R-material, which enables adding higher share of recycled material in the mixture. The mixing plant also includes the device for producing foam asphalt located directly next to the mixer. Water is supplied by piping via a small balance tank, and the pump feeds it in the horizontal mixing cylinder, where asphalt is supplied at the same time via the piping. The produced foam asphalt is supplied to the mixer via a short piping. Low temperature asphalt mixture is produced at 130 °C. After the supply to the construction site, the mixture temperature was measured with contact-free thermometer at 115 °C. The travel distance from the mixing plant was 35 km. The proposal of NTAS mixture for this location was processed at ČVUT. At the end of July 2014, the visual inspection was performed for completed layers which passed the 3O]HĖ winter period, i.e. ten months.

The telematic system project for the traffic node Zlín, is designed in the first phase for the collection of traffic information, mostly the arrival time (holdup time during passing the node at certain times, during obstacles expected and unexpected) and proportional division of the traffic intensity between the selected sections.

+ROHãRY

The system operates on the measuring principle of the specific vehicle travel time (clearly defined) through the specific nodes. The location of the detection place is defined below. The vehicle with active blue-tooth device is detected by passing in a close vicinity to the switchboard with the BTT detector (the direction antenna leads from the switchboard for receiving BTT signal). Such detected vehicle.URPČĜtå is registered in the vicinity of all installed detectors. During the detection physical address of the device is stated with the time of passing. Such information is sent to the evaluation server, which performs the data fusion and separation. The data are then implemented in the database with the respective data and further evaluated. The output evaluation contains the arrival time among the nodes and proportionate division of vehicle intensity from the total number of detected vehicles.

Application and evaluation of low acoustic shielding efficiency at the operated railway section Brno – Zastávka u Brna (operation verification)

Low acoustic shielding BRENS® BARRIER

7LãQRY %ODQVNR

The operation solution included the low acoustic shielding BRENS® BARRIER, which unlike high noise protection walls does not form completely new construction works dividing the area.

.XĜLP

The advantage of the shielding is a simple assembly and disassembly during the replacement of the railway top, the option of additional installation to the operating tracks, simple dismounting during emergency events, and lower acquisition and operating costs.

%UQR

Subsequent measuring verified the efficiency of low acoustic shielding to be applied within the construction „Electrification of route incl. PEÚ Brno, Zastávka u Brna“. Low noise shielding will be placed on the base layer at the ground level of railway tracks at 1.730 m from the rail axis. The shielding height is 0.730 m above the rail top, and the upper side of the parts is located as close as possible to the travel cross section of the tracks. Low noise shileding BRENS® BARRIER enables to evacuate passanger from the wagon, it forms external walking route, and space for survival in the rail direction. On the railway side there is a part fitted with noise absorption layer comprising of recycled items with noise absorption min. A3. The parts are located to the joint; the butt joint is sealed with rubber profile fitted on one side to the part. Mutual position of the parts is fixed by built-in rubber pins. The parts on the external rail side are fitted with threaded cases (fixtures) for handling during assembly and for pulling out any of them during rescue service intervention in case of emergency on the track. The application of low noise shielding for high speed railways is designed mostly for the solution of noise elimination of the railway stations passages or noise elimination of rails on bridges or embankments.

New technology and re-profiling of soft side strip of roads 1RYê II. and III. Class in Pardubice Region %\GåRY

The purpose of this new technology was to create such machine set that enables the completion of recycling in low width, only in the location of damaged edges, which significantly reduces the volume of all works. Such a solution is efficient and environmentally friendly due to power and resources saving. Due to the application of recycling only on damaged sides, there is no risk of defects caused by unstable edges during their excavation, and the necessity to scale the layers is reduced to minimum, i.e. only in case of removing the grinding layer in the edges before the milling. In the area of Pardubice region, a test section was selected of road III/322 35 Medlešice–Dřenice, 800 meters long, which formerly underwent the extension without reinforcement of the base layers, and which indicates surface deformities after the extension, including net cracks, whilst the road centre is in a relatively good state. With the financial participation of SFTI, the sample repair work was completed with the new technology of re-profiling the soft edges.

The completed test section indicates that the new re-profiling technology of soft sides is realistic and significantly reduces the volume of performed works, material and power consumption.

+UDGHF .UiORYp

In the past, many roads were extended in width due to unsuitable layout. It was performed in a way the existing, commonly blockstone roads, were extended on both sides approximately by one meter only in the cover layers, without constructing sufficiently reinforced sub-layers. Such dimensioned edges became significantly under-dimensioned, hence soft. Therefore, the edges on such roads are significantly damaged.

During re-profiling, a good milling machine function was proved that can level the transverse unbalances and level the recycled layer, which enables fitting a roller behind the milling machine. During reinforcement, the roller run must be travel with its full length in the milling machine area on material of the recycled layer, and it must not travel on the hard edge of the original solid base in the central part of the transverse profile, because it would reduce its effects on reinforced layer.

Road I/27 with new noise protection carpet

The construction subject of the project was the repair of road surface I/27 in section Kaznějov – Plaská Street. The repair work starts behind the railway crossing in Kaznějov at the transverse drainage trough, the end of the repair is on the joint of former repair at the entrance to the petrol station in Kralovice direction. Total repair length is 444,50 m, surface 3797 m2. The road indicates net cracks, rails, and many minor repairs in the defined section. The goal of the construction was to verify the function and service life of the technology with rubber-asphalt binding on heavily loaded road class I. The project implementation should prove the noise protection efficiency of the designed technology, permanent function features, and sufficient service life.

.UDORYLFH

Rubber-asphalt binder (CRMB – Crumb Rubber Modified Binder) can be a significant alternative to the existing types of modified asphalts. CRMB binder should indicate higher service life and stability of properties than currently common PmB binders on SBS base. Rubber-asphalt binder indicates high elasticity and higher resistance to formation and spreading of cracks. If such an innovative technology is applied correctly, it can significantly extend the service life of tarmac roads, suppress the formation of cracks, pot-holes, and limit the plastic deformations due to higher viscosity. The specific goals of the designed project included the verification of the new technologies on short section of road I/27 in Kaznějov, which was formerly selected and processed in the project for deep repair work of asphalt cover. The verified technologies and processes include: 1êĜDQ\ • New type of binder modified with rubber granulate • Noise protection carpet SMA 8 LA with CRMB binder • The application of CRMB binders in the base layers ACL 22S thickness 80 mm The road traffic load in the section is 19691 heavy freight vehicles/24 hours, the total of 7004 vehicles/24 hours, according to measuring from 2010.

2VWUDYD The application of the new technology was performed on road section II/480 at length 1150 m in Kopřivnice based on the location of special noise protection of bituminous mixture VIAPHONE® 30 mm.

%tORYHF

The project was based on milling the original layer at thickness 70 mm, cleaning the road, in the design of connecting spray 0,3 kg/m2, in location of ACO 45 mm, and in subsequent location of special noise protection layer. Prior to the repair work commencement, the daytime noise pollution was 69,9 dB, the noise pollution at night reached 62,0 dB +/- 1,8 dB. After the implementation, the control measuring was performed and the resulting daytime noise pollution was 64,0 d, and night time 55,7 dB +/- 1,7 dB. The road repair work fulfilled the purpose of reduced noise pollution in protected outdoor area. Noise measuring before the location and after the location of silent surface, the noise pollution level at daytime was lower by 5,9 dB and by 6,3 dB at night time. VIAPHONE® efficiently and permanently reduces the emissions of rolling noise. At the same time it is less susceptible to clogging, unlike the drainage asphalt. Its properties are unsuitable for the construction of town and periphery roads and the town streets, bypasses and roundabouts or peripheral and access roads.

The physical principle is the absorption and dispersion of air pressure in the layer with increased gap rate. It is possible to reach the acoustic pressure drop at night time by 4 – 6 dB.

The grinding layer from sound absorption carpet has higher gap rate than present in common mixture which results in the improvement of water drainage from the road. This fact helps to accelerate water drainage from the road surface because water is drained in its own layer to the road side.

Prior to the commencement of the construction works, the measuring of noise emission was performed during daytime and night time traffic. After the completion, the measuring was performed again and the noise level dropped in the daytime by 3,2 dB and at night time by 1,9 dB.

The limits of cracks and plastic deformations are achieved by completing the load layer with dispersed reinforcement with aramide fibres. The additive results in the growth of softening point and the reduction of binder penetration; it also increases the resistance to tangential forces affecting the layer. The result is the restriction of the crack transmission from the load layers and increased resistance to plastic deformations.

Je však nutné dále definovat podmínky sledování zkušebních úseků v delším časovém období a definovat metodiku hodnocení úspěšnosti ověřované technologie tak, aby investované prostředky byly využity v maximální možné míře a úspěšné projekty mohly být rozšířeny v praxi.

In 2012, two test sections were implemented on the road II/204 in the section Mrtník–Kaznějov focusing on the use of higher amount of asphalt recycled material in the asphalt cemented cover layer, in the amount larger than so far permitted by valid standard ČSN EN 13108-1 for asphalt concrete. The project and the implemented test sections aim to prove the option of adding higher amount of recycled material in the asphalt mixtures, i.e. adding recycled asphalt even in mixtures, where it is not so far permitted. The grinding layer in both sections was therefore completed with 20% and 40% R-material and 30% and 50% R- material in the load level.

Review of the test sections Tabulka 1: Přehled sekcí zkušebního úseku

The defined production process should establish the option of higher substitution of new natural stones, and also ecological re-use of recycled material with partial activation of the original asphalt binder and minimized power consumption for the production process.

At the same time, an additive substance was applied in both asphalt type by means of direct feeding in order to reduce the operating temperatures for the asphalt mixture production or to extend the interval of its processability: It also means to enable more ecological use of R-material without the necessity of excessive R-material heating and thus limit the temperature preconditioned material degradation.

Another goal of the implementation was to verify the effects of the asphalt mixture mixing period in the mixing plant on the resulting properties of asphalt mixtures.

Verification of new technology of cold emulsion asphalt mixture

Condition before implementation 5êPDĜRY

Production of cold emulsion asphalt mixture (EAC)

%UXQWiO

The production of asphalt mixtures in the mixing plants include high power consumption due to the heating and drying of large stone volumes, asphalt heating, and concurrently high electricity consumption required for hot gas and dust exhaust from the drying drum. One of the methods how to reduce the power consumption in the asphalt mixture technologies and how to remove the greenhouse gas emission, is to mix stones with asphalt emulsion at common temperature without heating, additionally with the option of the use of moisty stones. The goal of the project was to verify the technology of cold emulsion asphalt mixtures for the first time in the Czech Republic in the construction of road in use on a suitable test section.

8QLþRY

Olomouc Region operates approximately 3108 km of road class II. and III., and 20 % are currently in adverse or emergency condition. This condition can no longer be resolved by means of common maintenance or local repairs, but it is necessary and required, as regards safety and sustainability, to replace the whole asphalt cover, which has reached the end of its service life. /LWRYHO The test section was custom made to verify one possible repair method of road class II. and III., using environmentally friendly method and also efficient method as regards the financial costs. Based on the evaluation of all requirements of the project, the selected test section was on road III/4441 Domašov nad Bystřicí – Moravský Beroun in km 3,492 to km 5,320 i.e.1815 m in length.

The tested technology of cold emulsion asphalt mixtures proved that in the future it can partially replace the most frequent technology of hot asphalt mixtures, and enable more significant development of construction and reconstruction of the roads with lower traffic load. At the same time, they represent an important group of mixtures, which was so far missing within the whole scope of available hot technologies, i.e. asphalt mixtures, low temperature asphalt mixtures, and foam asphalt Total costs:  CZK 11.606,228 Kč (including VAT) mixtures.
