Surface cracking is ine of major early distresses in newly constructed semi-rigrid pavements in China. Such semi0rigrid pavements usually consist of three layers of hot mix asphalt (HMA) mistures on top of a cement-treated aggregate (CTA) base over lime treated subgrade. To control the CTA base cracks reflected to the surface, a HMA binder course mixture is desired to be not only anti-reflective cracking but also fatigue resistant. This study was in an effort to investigate the reflective cracking problem on semi-rigrid pavements through a proper binder course mixture design and laboratory characterization of the fatigue and anti-cracking properties of binder course mixtures used in China
