粘土结碎石路是用不同的级配碎石和粘土,分层铺装,籍压路机碾压,使其互相嵌桥粘结而成的一种过渡式的路面。我市所修筑的粘土结碎石路可区分两种:一种是用7～9公分碎石作承重层、4～6公分碎石作磨损层、1～3公分碎石与粗砂作封层,虚铺18公分,压实厚度12公分。另一种是用4～6公分碎石作承重层、2～4公分碎石作磨损层、0.5～2公分石屑与粗砂作封层,虚铺15公分,压实厚度10公分。经过四年来的行车考验证明这种粘土结碎石路是造价低廉,施工简便,效果良好的。根据我市目前发展情况,修筑粘土结碎石路有以下几点有利条件: 1.材料产地较近,成本造价低,在1956年度每平方公尺造价约2.50元。
Clay crushed gravel road is graded with different gravel and clay, layered pavement, roller roller compacted to form a transitional road surface embedding bridge. Clay gravel road built by our city can be divided into two kinds: one is 7-9 cm gravel for bearing layer, 4 to 6 cm gravel for wear layer, 1 to 3 cm gravel and coarse sand for sealing Layers, virtual shop 18 cm, compacted thickness of 12 cm. The other is 4 to 6 cm of gravel for bearing layer, 2 to 4 cm of gravel for wear layer, 0.5 to 2 cm of stone chips and coarse sand for sealing layer, virtual shop 15 cm, compacted thickness of 10 cm. After four years of driving test to prove that the clay crushed stone road is cheap, easy construction, the effect is good. According to the current development of our city, there are several favorable conditions for building clay-crushed gravel road: 1. The material origin is relatively close, the cost is low and the cost is about 2.50 yuan per square meter in 1956.
