MnDOT Pavement Design Manual April 10, 2018
Introduction
There are two documents that may be required to provide for a pavement project. A Pavement Design Memorandum (PDM) is required when the Alternate Bidding process is followed. This document enables the MnDOT Pavement Design Engineer to review and approve the pavement design. A Materials Design Recommendation (MDR) is required for all projects that include grading or pavement. It is used to document and communicate pavement and geotechnical design recommendations to the project designers. This chapter describes the content, development, review and approval processes of these two documents.

MnDOT Pavement Design Manual April 10, 2018
800 - Pavement Design Memorandum (PDM)
A PDM is required when the Alternate Bidding process is followed so that the pavement design can be reviewed and approved by the MnDOT Pavement Design Engineer. A PDM is written to document the alternate pavement designs that were considered, the information required for the pavement designs’ development, and the project’s LCCA. See Chapter 7 – Pavement-Type Selection to determine if the project will follow the Formal LCCA process and, therefore, will require the completion of a PDM. 1. Format The PDM template must be used for all PDMs. The template is available on the MnDOT Pavement Design website at http://www.dot.state.mn.us/materials/pvmtdesign/docs/index.html and directions for completing it are in Section 820 – PDM Template Instructions. 2. Distribution and Review A. The draft PDM is sent to the MnDOT Pavement Design Engineer. B. The MnDOT Pavement Design Engineer reviews the PDM and attachments and may request any necessary changes to be made. C. If the project will proceed to alternate bidding, the MnDOT Pavement Design Engineer will distribute the PDM to the FHWA Pavements, Materials and Construction Engineer and representatives of the Concrete Paving Association of Minnesota (CPAM) and Minnesota Asphalt Pavement Association (MAPA). The associations will have a comment period of two weeks and the MnDOT Pavement Design Engineer will address any comments. D. The MnDOT Pavement Design Engineer will sign the finalized PDM and the project may proceed with the pavement designs described in the PDM.

810 - Materials Design Recommendation (MDR)
The MDR provides pavement and geotechnical design recommendations for MnDOT projects to the project designer. This includes recommendations for layer thickness, materials, treatments, and specifications necessary to design the project. Note: Only the pavement designs that will be used in the project plans need to be included in the MDR. 1. Format A template for formatting the MDR is available on the MnDOT Pavement Design website at http://www.dot.state.mn.us/materials/pvmtdesign/docs/index.html. The template format is required for projects that will use Alternate Bidding. See Section 830 - MDR Template Instructions for directions for using this template. 2. Distribution and Review A. Complete a draft MDR. B. Complete a MDR routing sheet for the draft MDR. The MDR routing sheet template is available on the MnDOT pavement design website. C. Distribute the MDR and MDR routing sheet to the distribution list shown in Table 810.1. The method of distribution of the MDR, MDR routing sheet, and supporting documents vary by district preference and may be accomplished by e-mailing copies of the files, ProjectWise links, or electronic data management system (EDMS) links. These methods are all acceptable for review; however, the MDR, MDR routing sheet, and supporting material, must be archived in the MnDOT EDMS and should be placed there as early as possible. D. Provide for a review period of two weeks. E. Review comments, finalize, and archive the MDR.

Use of Paver Mounted Thermal Profile (PMTP) and Intelligent Compaction (IC) Methods Paver Mounted Thermal Profiling (PMTP) is the process of continuously monitoring and recording the location and temperature of the asphalt mat immediately behind the paver screed during placement operations. This identifies any thermal segregation in the uncompacted asphalt which may affect the pavement’s performance and durability. Intelligent Compaction (IC) refers to the compaction of road materials, such as soil, aggregate base, or asphalt, using self-propelled rollers integrated with a position monitoring system and an onboard documentation system that can display real-time, color coded maps of roller location, number of passes, roller speeds, amplitudes and vibration frequencies of the roller drum. Some systems are also equipped with drum vibration instrumentation, infrared temperature sensors, and/or automatic feedback control. The onboard documentation system on these rollers also displays real-time, colorcoded maps of stiffness response or pavement surface temperatures, or both. This improves monitoring and recording of the compaction process to ensure that the material is properly and uniformly compacted. The PMTP and IC methods are recommended for use when the following project/site conditions are met: 1. The technology can be used with the following specifications:

IC is recommended for use on 2353, only when used in conjunction with 2360 (i.e., when IC is already being used with 2360).
2. Net lane miles are greater than or equal to 4. Note: These technologies can be used on smaller projects. It is anticipated that the recommended lane miles will decrease with time as more contractors are equipped with these systems.

3. Cellular coverage, to allow for automatic transfer of data to the cloud, at least one time per day. Areas with intermittent locations of limited to no cellular coverage are allowed within the project limits, since the systems can store data until adequate data cellular coverage is available. 4. Adequate global navigation satellite system (GNSS) coverage through the project limits is required for recording of the real-time, spatial location of equipment. Table 830.2 lists the required accuracies.

Removals Any needed directions to the designer to provide for the removal of existing materials.
Geotechnical Recommendations Special Treatments Swamp areas, shadow treatments, rock excavation, or subgrade corrections: For any of these areas specify:
The depth of the correction/treatment and its limits (Section 320.2) The backfill material and its specification (Section 320.2) Compaction testing (Section 330) Any tapers or transitions in materials (Section 320.4)
Embankment If there will be any additional embankment construction specify the: Embankment material, its specification, and any plan note or special provision edits to modify the material (Section 320.3) Compaction testing (Section 330) Application of any surcharge (Section 320.3.c) 58

Monitoring equipment (Section 320.3.d) Topsoil If construction activities will disturb any topsoil, provide the depth of topsoil to be stripped and reused. Borrow Shrinkage Factor If there will be a quantity of borrow using specification 2105 then develop a borrow shrinkage factor (Section 340). Culverts Frost depth and soil-type: Provide an estimated frost depth and soil-type (plastic or granular). This information is used to select the correct culvert backfill treatment (Section 360.1). Fabric: Specify if any geotextile fabric, and type, (Section 360.2) should be included in the culvert backfill treatment. Plastic Soil Cap: Specify if a plastic soil cap treatment (Section 360.3) is required for any culverts. Modifications: Give full instructions, and specify the materials, of any modifications to the standard culvert backfill treatment drawings (Figures 360.1-4).
Plan Notes Provide the text to any notes to be included in the project plans.
Edits or Additions to Special Provisions Provide any changes or text that is intended to be added to any special provisions.
Attachments: Attach or provide a link to the location of the following: Printouts of the pavement design programs’ output for each pavement design. Signed traffic forecast summaries. Soil borings and cores (or link). The LCCA and any supporting calculations. Any LCCA or alternate bidding exceptions. Any GPR, geotechnical, or other reports. 59
