Safe and noise-reducing pavement material and preparation method thereof
The invention discloses a safe and noise-reducing pavement material and a preparation method thereof. The pavement material comprises aggregate, mineral powder and an asphalt composition, and the porosity of the pavement material is 20% +/-1%. The pavement material provided by the embodiment of the invention at least can solve the following problems that the internal environment of a tunnel is closed, and along with the increase of the length of the highway tunnel, various sounds of internal vehicles and the like are reflected by a wall surface for multiple times to generate a relatively large noise value, so that the physical and psychological health of drivers and conductors, maintenance personnel and other operators in the tunnel is seriously influenced, and driving safety is threatened. According to the pavement material disclosed by the invention, by controlling the porosity, the pavement structure formed by the pavement material can have openings in the surface and proper communicating pores in the pavement structure, so that the tunnel noise can be effectively reduced, and the safety and comfort in the construction and operation processes are improved.
本发明公开了安全降噪的路面材料及其制备方法。该路面材料包括集料、矿粉和沥青组合物，路面材料的孔隙率为20％±1％。根据本发明实施例的路面材料，至少具有如下有益效果：隧道内部环境封闭，随着公路隧道长度的增加，内部车辆等各类声音在内部经壁面多次反射产生较大的噪声值，严重影响司乘人员、检修人员以及其他隧道内部作业人员的身心健康，威胁行车安全。而本申请的路面材料通过控制孔隙率，使得路面材料形成的路面结构可以在表面存在开口、内部存在适当的连通孔隙，可以有效降低隧道噪音，提高施工和运营过程中的安全性与舒适性。
