江阴大桥钢桥面浇注式沥青混凝土铺装车辙破坏分析

浇注式沥青混凝土具有优良的防水、抗老化性能,抗疲劳性能以及对钢桥面板优良的随从性,是一种理想的钢桥面铺装材料。但浇注式沥青混凝土应用于我国的江阴大桥却出现了较为严重的车辙问题。为分析浇注式沥青铺装未达到设计年限便产生车辙破坏的可能原因,本文从铺装使用的交通条件、气候条件以及混合料设计等方面进行了探讨,以便为我国的相关研究提供有益的借鉴。

Study on Rutting of Gussasphalt on Jiangyin Bridge Steel Deck Pavement

The performances of the gussasphalt are fine,such as water proof,fatigue resistance and bonding with steel deck.Naturally,it is a kind of ideal steel deck surfacing material.However,the stability at high temperature of gussasphalt pavement of Jiangy in bridge over the Yangtze river is not so good.This paper analyzes the possible reasons for the early rutting damage to the Jiangyin bridge such as traffic and load condition,climate condition and mixture design,which may provide reference for relative research.
