Cement stabilized macadam base and construction method thereof
The invention discloses a cement stabilized macadam base and a construction method thereof, and belongs to the technical field of highway pavement pavements. The cement stabilized macadam base comprises aggregate, cement, water, a polymer mixture, magnetized polyvinyl alcohol fibers and serpentine asbestos powder; and the base is prepared by mixing and constructing the following components, by mass, 4.5% of the cement, 4.5% of the water, 0.3-0.97% of the polymer mixture, 0.6-3% of the magnetized polyvinyl alcohol fibers, 1.5% of the serpentine asbestos powder, and the balance of the aggregate.In the present invention, through mutual cooperation of the designed polymer mixture, the magnetized polyvinyl alcohol fibers, the aggregate and the serpentine asbestos powder, the water resistance is improved, the tensile strength of the cement stabilized macadam base can be effectively enhanced, the influence of temperature, humidity and the reaction effect exerted by a running vehicle due to the friction effect on the base can be weakened to a certain extent, cracking is avoided, the drawing effect of external force can be continuously resisted after cracking within a certain extent range,and the cracking speed of the base is effectively reduced.
本发明公开了一种水泥稳定碎石基层及其施工方法，属于高速公路路面铺设技术领域，包括以下组分：骨料、水泥、水、高分子混合物、磁化聚乙烯醇纤维以及蛇纹石石棉粉；由如下质量百分比的组分混合后施工而成：水泥4.5％、水4.5％、高分子混合物0.3％‑0.97％、磁化聚乙烯醇纤维0.6％‑3％、蛇纹石石棉粉1.5％、其余为骨料。本发明中，通过设计的高分子混合物、磁化聚乙烯醇纤维、骨料以及蛇纹石石棉粉之间的互相配合下，能够有效增强水泥稳定碎石基层的抗拉强度，可在一定程度上削弱温度、湿度以及所行驶车辆因摩擦作用而施加的反作用效果对基层的影响，避免开裂，且在一定程度范围内开裂后，能继续抵抗外力的拉拔作用，有效减缓基层的开裂速度。
