摘要
冬季雨雪、低温等恶劣天气会造成桥面铺装层的摩擦系数变小;夏季沥青混凝土在高温下产生“塑性变形”的特性容易造成车辆方向难易控制,引发道路交通事故。因此,需要冬季及时有效地融化桥面冰雪,夏季对桥面时时降温,在减少交通事故发生的同时也有利于延长桥梁的使用寿命,保证公路建设的投资效益。本文就一种桥面铺装内融雪、降温装置从其技术原理、技术安全可行、设置科学、布局合理、设备安全可靠、材料安全稳定等方面进行探讨。
Rain,snow,low temperature and other bad weather will cause the friction coefficient of bridge deck pavement to decrease in winter,while asphalt concrete produces"plastic deformation"under high temperature in summer,which easily leads to the difficult control of vehicle direction and road traffic accidents.Therefore,it is necessary to melt the ice and snow on the bridge deck timely and effectively in winter,and cool the bridge deck constantly in summer,which can not only reduce the occurrence of traffic accidents but also prolong the service life of the bridge and ensure the investment benefit of highway construction.This paper discusses a kind of snowmelt and cooling device for bridge deck pavement from its technical principle,technical safety and feasibility,scientificity of the setting rationality of the layout,and safety and stability of equipments and materials.
