级配路面 用天然砾石或机轧碎（砾）石按最佳级配原理将粗、细料及粘土进行配料,拌和铺筑的路面,又称级配碎、砾石路面。具有较高的密实性、水稳性和一定的力学强度，所用石料须在4级以上，面层混合料塑性指数在8～14之间。基层混合料塑性指数不大于4。 级配混合料可以根据粗、细料料源筛分结果。按规定要求，用计算法或图解法进行配料。施工时可用平地机、多铧犁或人工拌和。先摊铺粗料，次铺粘土，再铺细料，按最佳含水量边拌边洒水，松铺系数为1.3～1.4。混合料拌匀摊平后，先轻压2～3遍，再重压6～8遍，至表面无明显轮迹为止。 为了减少路面的磨损和破坏并提高路面的平整度，多在级配碎（砾）石路面之上加铺磨耗层或保护层。磨耗层一般用20毫米以下具有级配的粒料并掺入结合料加水拌和铺成。保护层用掺有粘土的混合料铺筑，也可用干净的粗砂或小砾石铺筑。磨耗层及保护层亦常用于其他碎石路面。
