旧水泥路面加铺沥青面层的设计原理与施工要点分析

Paving Asphalt Road Surface of the Old Cement Pavement Design Principle and the Key Points Analysis of the Construction

水泥混凝土路面经过服役期以后,即使出现了断板开裂、板缝唧泥、板块间错台等疲劳状态,由于自身的强度与回弹模量较高,可以通过板体结构层的受力特点进行验算补强设计再利用,一般进行加铺沥青混凝土面层较为实用,尽量避免破除后的大修或重建。

The cement concrete pavement after standing, even if it appears the status of surface crack, plate seam sloping clay, the stage of intraplate fault state of fatigue, due to its high strength and modulus of resilience, it also can reuse through the calculation of the bearing characteristics of plate structure layer reinforcement design, generally the paving asphalt concrete pavement is more practical,and it try to avoid major repair or reconstruction after the break.
