Development of Improved Overlay Thickness Design Alternatives for Local Roads

The objective of this research project is to develop Hot Mix Asphalt (HMA) overlay thickness designs for a number of local road and street projects using (1) the currently used Modified AASHTO (Bureau of Local Roads and Streets Manual), (2) Asphalt Institute, and finally, (3) nondestructive Falling Weight Deflectometer (FWD) testing and layer modulus backcalculation based mechanistic-empirical (M-E) design procedures to demonstrate advantages/disadvantages of each approach and document the estimated construction cost of each design alternative.Based on results of design evaluations and research findings, Chapter 46 of the BLRS Manual will be revised to provide better guidance for local agencies to design cost effective overlays.
