Impact/Purpose:
To present an overview of the research approach, application history, and the initial results of two years of study.
Description:
In order to make improvements to conventional paving asphalt to make it more suitable for containment applications, Wilder Construction Co. of Everett, WA offers MatCon, a polymer modified asphalt system comprised of proprietary binder, when coupled with a selected aggregate type and gradation, a specialized job mix formula and installation specifications results in a potentially superior substitution for conventional paving asphalt in cover containment applications. Under USEPA's Superfund Innovative Technology Evaluation program, the system was installed and placed under study at two locations, with two more possible in 2001. MatCon is intended for use as a waste containment material, and can be configured to function as both a hydraulic barrier and as a drainage material, to comprise a single or multiple layer cover system. MatCon is noted for its superior engineering qualities and is designed for long-term performance, yet can be applied with conventional paving equipment. The hydraulic performance of the material was examined by both removing destructive samples for laboratory testing, as well as field evaluation. While the study focuses on hydraulic properties, accompanying engineering properties were evaluated in the laboratory. Finished MatCon can serve multiple purposes such as staging for trucks and construction equipment, pavement, and light industrial facilities. This presentation provides an overview of the research approach, application history, and initial results of 2 years of study.
