复合式长寿命路面设计标准研究

Design Standards for Compound Long-life Pavement

从长寿命路面的定义及特点可以看出,其优点在于设计寿命延长,养护费用较低,在寿命周期内的总费用最经济。由于其不需要进行结构性大修,只需进行日常的养护维修,因此对交通的干扰不是很大,完全有可能避免交通全封闭,这样给道路使用者带来的延误将会减少,由此带来的群众不满情绪以及道路有关部门的压力将会减轻。

It can be seen from the definition and characteristics of long-life pavement that the advantages of this kind of bridge are longer design life,lower maintenance costs,and the most economical cost the total life cycle.This kind of bridge does not require a structural overhaul,only need routine maintenance and repair.Therefore,the interference on traffic is not very large,and it is entirely possible to avoid traffic completely closing.Thus,the delay caused by road users,the resulting mass discontent and the road authorities′ pressure will be reduced.
