融冰降噪功能型沥青路面设计与应用研究

Design and Application Research of Functional Ice Melting and Denoise Asphalt Pavement

通过室内试验和工程应用,探索大空隙降噪沥青路面+抗凝冰涂层复合结构的可行性和可靠性。结果表明:融冰降噪复合功能型沥青路面结构可操作性强,融冰涂层涂刷过程中未出现明显下渗,仅对路表孔隙产生覆盖,路表无明显渗水,摩擦系数降低程度不显著,在行驶车辆的摩擦作用下,覆盖现象逐渐减轻,该复合路面结构的抗凝冰、降噪效果显著。

In this paper,the feasibility of the composite structure of large void noise reduction asphalt pavement and anticoagulant ice coating is explored through laboratory test and engineering application.The results show that the composite pavement is simple in implementation and strong in maneuverability.Although the coating has some blockage to the pavement pores,the influence is not obvious,and the pollutants can be reduced to a certain extent.The pavement structure has obvious effect of anti-freezing and noise reduction,and can effectively improve the driving comfort and safety of the pavement.It is in line with the concept of low carbon and environmental protection,and has potential application and promotion value.
