Roadway Concrete Barrier Design and Performance � Material Durability Issue

项目名称：	Roadway Concrete Barrier Design and Performance � Material Durability Issue
摘要：	Concrete barriers are installed to shield the traveling public from hazardous objects. They canserve to prevent errant vehicles from departing the travel way and to minimize vehicle damagesfrom crossover collisions. Wisconsin Department of Transportation (WisDOT) has beenbuilding single-slope concrete barrier on highway projects since 2011. It requires lowermaintenance cost, has better crash performance and it is more flexible with overlay projects. As the older barriers built using this design have been in service for several years, some of thebarriers have shown distresses that that may influence long term barrier durability andpotentially the safety of the barrier. A damaged concrete barrier typically requires lane closure,which leads congestions and creates more expensive user costs in addition to the repair cost. There are various possible causes for distresses and many of them could cause long term maintenance issues. There is a potential for some of the distresses to influence the safety performance of the concrete barrier. The goal of this project is to investigate concrete distresses showing in single-slope concrete barriers on highway projects and make recommendations to update current WisDOT barrier practices such as concrete barrier design, construction method, and maintenance procedure to achieve the long-term performance of them.
