摘要
透水铺装是生态水利工程建设的重要手段和途径,而基底材料对透水铺装的抗冻胀性能存在显著影响。文章以现场试验的方式研究了不同基底材料对透水铺装冻胀破坏的影响。根据试验结果,建议选择中砂材料和透水水稳材料分别作为找平层和垫层的首选材料。
Pervious pavement is an important means and approach for ecological water conservancy project construction,and the substrate material has a significant effect on the frost heaving resistance of pervious pavement.In this paper,the effect of different substrate materials on frost heave failure of permeable pavement is studied by field test.According to the test results,medium sand material and permeable water stable material were selected as the preferred materials for screed and cushion respectively.
