Opinion: Washington state pioneered efficient highway repair methods once — and can do so again

By NICK DAVIS International Grooving and Grinding Association

Highway departments face tight budgets and staff shortages while often resorting to costly and invasive “worst-first” repairs. Concrete pavement preservation (CPP) techniques offer an alternative solution by addressing minor issues before they become larger, more expensive problems, and ultimately save billions of dollars for highway agencies.

In the early 2000s, the Washington State Department of Transportation (WSDOT) pioneered the widespread adoption of one CPP technique, Dowel Bar Retrofit (DBR), restoring load transfer in aging jointed plain concrete pavement. By installing epoxy-coated dowel bars across faulted joints and following with diamond grinding, WSDOT extended pavement life by 15 to 20 years.   See the rest by clicking on the following link : https://www.djc.com/news/op/12175921.html
