平整度是高等级路面控制的主要指标之一,沥青混凝土路面面层强度低,承载能力差,强度主要靠面层以下基层、垫层和路基的强度,因此很容易出现坑凹、起拱、接缝台阶、碾压车辙、桥头跳车等多种病害,形成路面不平整现象,严重影响其使用质量。影响沥青混凝土路面平整度的原因很多,下面探讨如何提高沥青混凝土路面的平整度。 Flatness is one of the main indicators of high-grade pavement control. Asphalt concrete pavement surface strength is low, carrying capacity is poor, the strength mainly depends on the grass-roots level, mat and subgrade strength below the surface layer, so it is prone to pits, Joint steps, rolling rut, bridge jumping and other diseases, the formation of uneven road surface, seriously affecting the quality of its use. Affect the smoothness of asphalt pavement for many reasons, the following discussion on how to improve the smoothness of asphalt pavement.
