简易沥青碎石路面(亦称浅贯入式)是用不同大小颗粒的碎石或砾石分层铺筑,颗粒尺寸自下而上逐层减小,同时分层贯入热沥青,经分层压实而构成路面。简易沥青碎石路面强度较高,同时也要求底层有足够强度来支承。简易沥青碎石路面在力学特性上分属于柔性路面。路面的强度和稳定性,主要取决于碎石间的相互嵌挤和锁结所产生的摩阻力。属于嵌挤式类沥青路面。简易沥青碎石路面贯入沥青深度为3～5
Simple asphalt pavement (also known as shallow penetration) is the use of different sizes of gravel or gravel layered pavement, the particle size decreases from bottom to top, at the same time stratified penetration of hot asphalt, stratified Compaction and constitute the road. Simple asphalt pavement strength is high, but also requires the bottom of sufficient strength to support. Simple asphalt pavement in the mechanical properties of sub-belonged to the flexible road. The strength and stability of the pavement mainly depend on the frictional resistance caused by the mutual crowding and locking of the gravel. Belongs to the embedded type asphalt pavement. Simple asphalt pavement penetration depth of 3 to 5 asphalt
