• Abstract:
  Due to change of temperature and/or moisture, freezing-thaw cycles, loss of subgrade support by erosion, and traffic loading, concrete pavements can develop different types of distresses during service life. Hot mix asphalt (HMA) overlays are commonly used to improve the serviceability of damaged concrete pavements. The most challenging issue for HMA overlays over concrete pavements is the development of reflection cracks through the overlays at the locations of joints and existing cracks on concrete pavements. Even though different techniques have been used to overcome this issue, they often do not yield satisfactory results and performance. Cracking of HMA overlays results from intolerable tensile strain and/or shear movement developed in the overlays due to the movement of concrete pavements
