摘 要:通过正交试验研究了水胶比、砂胶比、粉煤灰掺量和剑麻纤维掺量对水泥基路面材料抗压性能和弯拉性能的影响。结果表明,高延性剑麻纤维水泥基路面材料的最佳配合比为:水胶比0.30、砂胶比0.4、粉煤灰掺量30%、剑麻纤维掺量0.5%,此时,试件的弯拉强度满足JTG D40—2011《公路水泥混凝土路面设计规范》的要求,且抗压强度较高,为66.62 MPa。
Abstract: The effects of water-binder ratio, sand-binder ratio, fly ash content and sisal fiber content on the compressive properties and flexural tensile properties of cement-based pavement materials were studied by orthogonal experiments. The results show that the optimal mix proportion of high ductility sisal fiber cement-based pavement material is: water-binder ratio of 0.30, sand binder ratio of 0.4, fly ash content of 30% and sisal fiber content of 0.5%, and the flexural tensile strength of the specimen meets the requirements of JTG D40—2011 Specifications for Design of Highway Cement Concrete Pavement, and the compressive strength is relatively high, which is 66.62 MPa.
