Additionally, adequate macrotexture helps the development of the hysteresis component of friction which is related to energy loss due to tire deformation because of motion on macro asperities and consequently increases pavement friction [5] [32] [33]. Simulation of the percentage of contact points within the contact area of a tire and pavement surface could give an estimation of the macrotexture of the pavement [32]. Davis et al. [34] showed that mixture parameters have a significant influence on the ribbed tire skid resistance measurements and laser profile mean texture depth. Moreover, they reported that according to HMA mix design properties, prediction of some of the frictional properties of the wearing surface mixes is possible [34]. Bloem [35] indicated that in order to assure enough depletion of water from under the tire, an average texture depth of about 0.5 mm (0.02 inch) as the minimum, is required [35].
