A wise supplement to other geotechnical methods Bearing capacity is an important parameter. Just as important as the compaction degree. PRIMA 100 is easy to use and provides first class measurements of the bearing capacity of natural soil and foundation layers. An integrated high precision load cell measures the impact load of each individual measurement providing a correct bearing capacity result irrespective of soil type and material. IDENTIFY ISSUES AS THEY OCCUR - BEFORE THEY ARE BURIED
PRIMA 100 for Construction QA
Monitoring foundation layers during construction
PRIMA 100 for control of Natural soil and earthwork materials Irrespective of whether the foundation is to carry a large industrial floor, a road, a parking area or other structures, it is crucial to know the surface bearing capacity measured on top of relevant layers. Only with this knowledge it is possible to be sure of a correct and optimum construction. PRIMA100 utilises an integrated high precision load cell for the measurement of the impact load of each individual measurement providing a correct bearing capacity result irrespective of soil type and earthwork material. PRIMA100 can measure on anything from clay to base gravel and crushed concrete. Knowing the bearing capacity of the soil and foundation materials ensures that the required performance is achieved. At the end of the day you save money.
Excavations and rehabilitation of road lanes Compaction: You can control the compaction degree of the excavated and reused often mixed materials. A correct compaction prevents lasting settlements and defects. Grontmij has prescribed a measuring procedure for PRIMA 100 for qualitative compaction control of backfill. Bearing capacity: Bearing capacity is as important as compaction. The stiffness of base courses is crucial in order to avoid cracking. Thus bearing capacity measurements are performed on old base layers immediately after the asphalt layer has been removed. The task is then to obtain the same bearing capacity with the new structure - or as close to as possible. In this way the new and the old asphalt will work uniformly and cracks can be minimised.
PRIMA 100 for control of surface bearing capacity Apply PRIMA 100 for quality control in connection with construction of foundation layers for roads or other areas. Measuring the bearing capacity on top of the individual layer, you will identify insufficiencies in time and these can be remedied. Or you may discover that the existing and built-in materials are better than expected allowing you to potentially reduce the volume of more expensive material. Time spent measuring surface modulus can save money and ensure construction quality.
PRIMA 100 for control in connection with Rail construction PRIMA100 is applied for control of natural soil and structure. When constructing foundation layers for track beds, the bearing capacity is essential. PRIMA100 controls the bearing capacity of soil as well as foundation layers under construction. PRIMA100 is applied on a routine basis when replacing crossings. Compliance with the specific requirements to soil and base gravel is controlled. The work needs to be performed as quickly as possible because all road and rail traffic has been stopped. The in-situ reading of e.g. bearing capacity, impact, deflection, time, GPS coordinates and automatic storage of data ensures this.

PRIMAX 1500 - Roads
PRIMAX innovation with excellence
Bearing Capacity of Pavements Every day your road pavements are subjected to the load from the traffic driving on them. When the roads were constructed, design values were calculated with regard to the load the pavements should be capable of carrying. But do the actual values match the design values? If not, the pavement may fail prematurely and over time you will see accelerated deterioration with expensive consequences. Monitoring the conditions of the pavement layers with the FWD gives you the early warnings of structural deterioration. Utilising a Falling Weight Deflectometer you can collect data to assist with the optimisation of budgets for pavement maintenance. Analysing and calculating data collected with the PRIMAX FWD using RoSy Design Software allows you assess the ongoing condition of the road pavement layers throughout the road network: • • • •

More than just a computer program... RoSy is a concept, which creates the logical connection between decision-makers, the financial consequences and the measures that are required on the individual road sections in order to comply with the political goals and strategies. Proper Road Asset Management is cooperation between qualified experienced road engineers and software. The road engineer must understand and respect the context, the software programs must form the basis for quality decisions to be taken by the political decisionmakers.
RoSy RAMS
A proven and genuine concept
The Concept benefits Software programs cannot replace humans, but they can systematically collect and process large amounts of data and present the results in a clear and well-arranged way. We offer to put our asset management experts at your disposal to ensure that the investment in a road asset management system will give full benefit and that the actual purpose of a RAMS - optimum and long-term maintenance - is complied with. Before RoSy can be taken into use, the road network, its geometry and condition must be collected and surveyed. Grontmij offer you to advise your technicians and engineers in this work. If such data already exists, then this data can usually be transferred to RoSy. The result is a modern and unique database which can communicate with other systems such as sewerage registers and geographic information systems (GIS).
The three basic software modules: RoSy BASE RoSy Base is the database module in the RoSy family. RoSy Base contains the main and condition data which are required for a RAMS. • An efficient reference system for daily operation • Road data is presented in a clear and comprehensive way • Easy to generate data analyses across a complete road network • Well set-out reports and graphics give good possibilities for retrieving road data • A good platform for other details related to the individual road RoSy PLAN RoSy PLAN is the calculation module, which on the basis of the basic and condition data of the roads in a major road network can calculate optimum long-term and/or short-term maintenance strategies. RoSy PLAN supports the decision process about priority of measures on a large road network • Consequences for the road network development of any limitation of the financial frames are presented clearly • Decision-makers get a clear picture of the consequences of limitations of budgets on road condition • Calculated measures for each individual road can be retrieved • Calculation models are based on many years of observations and analyses of deterioration of a variety of pavement types • Calculation setup can be adjusted to local conditions • RoSy has been utilised in Europe, America, Asia and Africa RoSy MAP RoSy MAP is the tool for visualisation of data from all RoSy modules. RoSy MAP allows the user to understand relations and lack of data, which may not have been discovered in the large amount of information stored in the database. Results and consequences calculated by RoSy PLAN can be visualised in a clear way in interactive maps • In the daily operation this tool is applied for looking up and analysing road data across the various networks • Data can be updated directly in the database • GIS layers with other details can be loaded and applied for presentation of RoSy data in a well-known context

Do your pavements match the loads Monitoring of your pavement conditions is a must to secure a smooth and safe operation of the airport. Today most airports around the world experience a steadily increase of in- and outgoing airplanes as well as new airplane types subjecting the pavements to much higher loads. The PRIMAX Heavy Weight Deflectometers are all about ensuring a safe infrastructure to move people and goods around in an innovative and environmentally sustainable way.
PRIMAX 2500 or 3500 - Airports PRIMAX innovation with excellence
Bearing Capacity of Pavements Every day your airfield pavements are subjected to the heavy load from aircraft traffic. When the airfield pavements were constructed, design values were calculated with regard to the load the pavements should be capable of carrying. But do the actual values match the design values? If not, the pavement may fail prematurely and over time you may see accelerated deterioration with expensive consequences. Knowing your pavements’ structural condition is vital in order to prevent your pavements from failing and it is important to keep monitoring the condition of the pavement layers with a Heavy Weight Deflectometer to report correct PCN values for the airfield pavements and for optimization of funds to be spent on pavement maintenance. Analyzing and calculating data collected with the PRIMAX HWD using RoSy Design Software, allows you to assess the ongoing conditions of the airport pavement layers when planning airfield pavement maintenance: • • • • •

RoSy Design
Making a difference
RoSy Design is the software applied for processing data collected by the PRIMAX FWD. The analyses and calculations made with the system provide road and airport authorities with valuable information about road and airfield pavements allowing decision-makers to make the right decisions with regard to reinforcement needs or maintenance strategies that will ensure safe roads and runways.
Results on site RoSy Design is integrated in the data collection software of PRIMAX and allows the operator to analyse deflection and load signals at any measured point on site. Calculations can be made on site or immediately after the measuring session and if parameters are changed, recalculations can be made. Results can be printed out per measuring point, section and project specifying the calculation parameters applied.
Parameter setups for several projects A large amount of parameter setups can be stored allowing selection of the best suited parameters for a particular project. Setup parameters are split into several levels and combinations can be selected and stored to be used again on projects with equal conditions.
Output roads A design part (RoSy DESIGN) processes an advanced design of the road pavement possible, while the calculation part (RoSy PLAN) is applied for calculation of maintenance options.
Output airfields Based on the calculated field data, PCN values (Pavement Classification Number) are determined for individual pavement sections. To determine whether the existing pavement is capable of carrying a given aircraft, the calculated PCN value is compared to an aircraft’s ACN value (Aircraft Classification Number).
Back-calculation method - technical information The RoSy Design program uses a backcalculation method. The calculation of the deflection of a pavement surface is based on the theory of elasticity and the method of equivalent thickness, as framed by J. M. Kirk and N. Odemark on the basis of Boussinesq´s equations. Calculation of reinforcement is based on fatigue relations and the stresses and strains caused by the actual traffic for which calculation of necessary overlay is required. For aircraft loads the areas, on which overlap is found, the equivalent factors are found by calculation of the fatigue caused by the individual aircraft in correlation to the fatigue caused by the Design Aircraft.
