Hot Mix Asphalt (HMA) overlays are among the most effective maintenance and rehabilitation alternatives in improving the structural as well as functional performance of flexible pavements. This study aims to: (i) demonstrate advantages/disadvantages of HMA overlay design procedures currently in use in Illinois, Indiana and Ohio, (ii) document and compare the estimated construction and life cycle costs of the different design alternatives, and finally, (iii) develop an advanced procedure for HMA overlay design that can incorporate critical pavement responses achieved by performing falling weight deflectometer (FWD) testing on pavement sections.
