Description
This paper will discuss the various hot applied and highly modified field blended binder materials that are currently being manufactured in the United States and utilized in chip and cape seal pavement preservation applications. These pavement preservation systems serve as alternatives to expensive construction or re-construction techniques.
Further discussion will focus on a specific chip seal design method which includes binder design and aggregate retention testing to determine materials compatibility prior to a project being constructed. Binder and aggregate application rates, proper aggregate quality and gradation, along with other construction issues and procedures; including traffic volume and climatic region are variables that will also be considered as part of this “design” process.
