Pavement Design Processes
Pavement Design Spreadsheets
IDOT Mechanistic Pavement Design and Life-Cycle Cost Analysis: This spreadsheet will perform the calculations required by Chapter 54 of the BDE Manual to determine a design thickness and conduct a life-cycle cost analysis.
PCC Inlay / Overlay Design Spreadsheet: This spreadsheet allows the designer to determine a design thickness for a PCC Inlay / Overlay based on the procedure developed through the research project ICT-R27-3 “Design and Concrete Material Requirements for Ultra-Thin Whitetopping Procedures”.
