From Potholes to PMB Plants
Charleston County, South Carolina in the United States has 380 rural dirt roads which require ongoing maintenance and the authority needs to pave them to reduce its maintenance bills. Traditional paving methods are not economically feasible because new regulations make the permitting process cumbersome and working the drainage system around protected trees and driveways can be bothersome for residents, not to mention the expense. This article discusses how there is a need for something that is economical, constructible, and sustainable. The solution is pervious, or porous paving: open-graded friction course asphalt with 20% air voids allows water to drain through so that costly drainage systems are not needed. Though this solution has been around for a long time, the mix containing Evotherm offers a more cost-effective option and the creation of a new mix design that incorporates the warm mix additive Evotherm is described in this article.
