抗裂嵌挤性水泥稳定碎石基层属于骨架密实型基层,这种基层具有较高的强度。4.75 mm筛孔通过率、集料类型和水泥的剂量对混合料的强度具有影响。试验结果表明,4.75 mm筛孔通过率和水泥剂量与强度成正相关的关系,不同的集料类型,混合料的强度的变化规律也是不一样。同时,在水泥剂量较小的情况下,混合料的强度也可以达到水泥稳定碎石基层强度的要求。
Crack-resistant jacketed cement-stabilized macadam base belongs to the skeleton of the compact base, this base has a high strength. 4.75 mm mesh passing rate, aggregate type and cement dosage have an impact on the strength of the mix. The test results show that the passing rate of 4.75 mm sieve and the relationship between the dosage of cement and the strength of the cement have a positive correlation, and the variation rules of the strength of different aggregate types and mixtures are also different. At the same time, in the case of a small amount of cement, the strength of the mixture can reach the strength of cement stabilized gravel base requirements.
