Composite pavement road with asphalt layer coated on sisal hemp fiber cement-based composite material
The invention provides a composite pavement road with an asphalt layer coated on a sisal hemp fiber cement-based composite material. A pavement structure of the composite pavement road sequentially comprises an epoxy asphalt concrete surface layer, an interface performance enhancing layer, a sisal hemp fiber cement-based composite material bearing layer, a base layer and a sub-base layer from topto bottom. And the base layer is made of graded stabilized macadam with a flexible characteristic. Main components of the sisal hemp fiber cement-based composite material are cement, fly ash, fine sand, a superplasticizer, an adhesive and sisal hemp fibers, and the sisal hemp fiber cement-based composite material is used as a bearing layer, so that early-stage diseases such as pavement cracks, water damage and ruts can be effectively prevented, the pavement durability is greatly improved, and the service life is prolonged. The coated asphalt layer can improve driving comfort. Meanwhile, due tothe fact that the thickness of the asphalt layer is reduced, the manufacturing cost of the road surface can be remarkably reduced, environmental protection is facilitated, and good social benefits and huge economic benefits are reflected.
本发明提出一种剑麻纤维水泥基复合材料上覆沥青层复合式路面道路，其路面结构从上到下依次为环氧沥青混凝土面层、界面性能增强层、剑麻纤维水泥基复合材料承重层、基层和底基层。所述基层采用具有柔性特点的级配稳定碎石。所述剑麻纤维水泥基复合材料的主要成分是水泥、粉煤灰、细砂、高效减水剂、粘合剂和剑麻纤维，采用剑麻纤维水泥基复合材料作为承重层可有效防止路面裂缝、水损坏、车辙等早期病害产生，大大提高路面耐久性，延长使用寿命。上覆的沥青层后可改善行车舒适性，同时由于减薄了沥青层厚度，可显著降低路面造价，利于保护环境，体现出良好的社会效益与巨大的经济效益。
