掺加聚丙烯纤维的水泥稳定碎石配合比设计研究

水泥稳定碎石基层属于半刚性基层材料，容易产生收缩裂缝。通过掺加不同比例的聚丙烯纤维。按照抗裂性能和劈裂强度最优的原则，找出掺加聚丙烯纤维的最优配合比，可以有效地提高水泥稳定碎石的抗裂性能，从而提高路面的耐久性。

Cement Stabilized Broken Stone Mixture Ratio Design with Polypropylene Fiber

Cement stabilized broken stone to creating shrinkage crevice. Through mixing ratio of polypropylene fiber is found out in base belongs to semi-rigid base material, which is inclined polypropylene fiber of different ratios, the optimum mixture light of the principle of optimizing anti-crack property and cleavage strength, so as to improve effectively the anti-crack property of cement stabilized broken stone. In this way is the durability of pavement improved.
