绿色环保型高性能沥青混凝土排水铺装用防水材料应用研究

Application research on the green high-performance waterproof material for asphalt concrete drainage pavement

介绍了一种沥青混凝土排水铺装用的高性能树脂型防水材料以及其作为防水层所具备的性能优势。其优异性能表现在与沥青混凝土基面的粘结强度达4.07 MPa,与混凝土基面的粘结强度达3.51 MPa,低温弯折性可达-20℃,同时在1.8 MPa的压力下24 h不透水,耐磨性优良。不仅能够实现防水层与基层之间良好的相容性,同时避免了在实际工程中存在的因防水层性能缺陷带来的经济损失。

This article introduces a high-performance resin-based waterproof materials for drainage pavement with asphalt con- crete, and its performance advantages as waterproof layer. Its excellent performance includes：4.07 MPa of adhesion to asphalt concrete base surface,3.51 MPa of adhesion to the concrete surface,low temperature flexibility of up to -20 ℃,no impervious after 24 h under 1.8 MPa pressure, excellent abrasion resistance. It can not only achieve good compatibility between the waterproof layer with the sub- strate, but also avoid the economic losses due ＂to performance deficiencies in the waterproof layer exist in the real project.
