一、施工前的准备工作和材料规格要求弹石路面是用不规则小块石料铺砌的一种块料路面。它的使用质量主要取决于所用的石料耐磨性能和路基的坚实稳定程度,所以在施工之前首先要做好石料强度鉴定和路基恢复工作;尤以排水是否良好更为重要,因为这对路面铺后的质量关系重大。1.石料的选择。只要极限抗压强度为800～1,200公斤/平方厘米就能满足要求,如花岗岩、石灰岩及坚硬的页岩都可以选用。2.弹石规格一般为顶面长8～12(10～16)厘米,宽6～8(6～10)厘米,高9～12(10～12)厘米。要求平均顶面积不小于70平方厘米。底面积不小于40平
First, the preparation of the pre-construction work and material specifications require the elastic rock pavement is irregular block of stone paving a block of pavement. The quality of its use depends mainly on the wear resistance of the stone used and the stability of the roadbed, so in the construction of stone strength before the first identification and recovery of subgrade work; especially drainage is more important or not, because this shop pavement The quality of the relationship after the major. 1. The choice of stone. As long as the ultimate compressive strength of 800 ~ 1,200 kg / sq cm to meet the requirements, such as granite, limestone and hard shale can be used. 2. The specifications of the rock are generally 8 to 12 (10 to 16) cm long, 6 to 8 (6 to 10) cm wide and 9 to 12 (10 to 12) cm long on the top. Requires an average top area of not less than 70 square centimeters. The bottom area of not less than 40 flat
