![]() Pavement designers should work closely with the SHA component responsible for traffic volume, classification, and truck weight data required for pavement design. Highway agencies should pay particular attention to the following items in designing pavements. To promote consistency in application of mechanistic-related design procedures, the Office of Pavement Technology will participate with the Resource Centers and Division Offices in reviewing and discussing these procedures with the State during their development. The FHWA encourages the development of mechanistic pavement design procedures.If the reviews show that the SHAs have and are following an acceptable pavement design process, routine pavement design reviews of individual projects will not be required. As part of the review, FHWA field offices will sample a sufficient number of projects to determine that the pavement design process is being followed and the process provides reasonable engineering results. ![]() Consistent with FHWA's operational philosophy on process review/product evaluation (PR/PE) attached to Executive Director Carlson's November 12, 1991, memorandum, the FHWA field offices can conduct periodic reviews of the SHA's pavement design process.FHWA Evaluation of Pavement Design Procedures.The SHA may use the design procedures outlined in the "AASHTO Guide for Design of Pavement Structures," or it may use other pavement design procedures that, based on past performance or research, are expected to produce satisfactory pavement designs. Instead, each State Highway Agency (SHA) is expected to use a design procedure that is appropriate for its conditions. General Pavement Design Considerations (23 CFR 626) Title 23 CFR 626 establishes the following requirement: "Pavements shall be designed to accommodate current and predicted traffic needs in a safe, durable, and cost-effective manner." The regulations do not specify the procedures to be followed to meet this requirement.See Order 1321.1C FHWA Directives Management If you have data in a Version 1 spreadsheet and would like it updated to Version 2, contact you get an error message when using a macro workbook, follow these instructions: How to Enable Macros in Excel (PDF).Formerly Federal-aid Policy Guide Non-Regulatory Supplement NS 23 CFR, Part 626,.Bituminous Testing Spreadsheet (Excel) - Version 2.PaveCool: asphalt pavement cooling tool.TONN2010 refresher course (PowerPoint) - presented on Oct.TONN2010 does not work with 64-bit Excel.ESAL Forecasting & Planning Tool (Excel Macro Workbook, 48 MB) - Updated June 15, 2023.MnPAVE 7 beta Version 7.012 updated December 20, 2023.MnPAVE Rigid and Flexible Pavement Design (PowerPoint), presented on November 16, 2022.Download just the MnPAVE-Rigid3.exe program without the installer.MnPAVE Rigid 3.0: rigid (PCC) pavement design Version 3.002 updated May 13, 2019.MnPAVE Flexible: flexible (HMA) pavement design.ACPA K-value calculator: For use with BCOA-ME.BCOA-ME: bonded PCC overlay (whitetopping) design.If you do not see an icon on your desktop, click the Windows Start menu and type "Software Center" Please use the Software Center to install the following applications on MnDOT computers.
