DYNAMIC DESIGN OF AC OVERLAYS USING DEFLECTION TESTING
A wide variety of techniques have been tried to eliminate or minimize reflective cracking of asphaltic concrete overlays placed on existing concrete pavements. Of these, the fracture techniques have gained increased acceptance over the last 10 years, but very little fundamental knowledge concerning design, construction, and performance models is available. To improve the state-of-the-art and develop a better understanding of these techniques, a nationwide evaluation study was undertaken. This study led to the field evaluation of more than 100 construction projects where these techniques had been used. In this paper, a detailed discussion of the dynamic design methodology is presented.
