沥青混凝土路面是用沥青作粘结料修筑面层并与各类基层结合所形成的路面。由于使用了沥青粘结料,增强了矿料间的粘结力,提高了混合料的强度和稳定性,具有坚实、平整、抗滑、耐久的品质和高温抗车辙、低温抗开裂、抗水损害及防止雨水渗入基层等功能。沥青面层质量的好坏直接影响着行车的安全和舒适,保证沥青面层不受损坏对维持正常交通至关重要。沥青路面的破损原因很多,其中沥青路面水损害就是其中的一类。
Asphalt concrete pavement is made of asphalt binder for the construction of the surface and the formation of various types of grassroots pavement. As a result of the use of asphalt binder, and enhance the bond between the mineral aggregate to improve the strength and stability of the mixture, with a solid, smooth, anti-skid, durable quality and high temperature anti-rut, low temperature cracking resistance, Damage and prevent infiltration of grassroots and other functions. The quality of asphalt surface layer directly affects the safety and comfort of driving, to ensure that the asphalt surface is not damaged to maintain normal traffic is essential. Asphalt pavement damage many reasons, including asphalt pavement water damage is one of them.
