The quality of materials incorporated into SCDOT construction projects is essential in the acceptance and overall quality of the final product. Materials are assessed to ensure adherence to specified requirements by varying methods including field testing, laboratory testing, and manufacturer certifications.

In addition to the SCDOT Qualified Products Lists, the information below provides guidance for ensuring that the minimum requirements for these construction materials are met.


Research & New Products

The SCDOT Research Program Website is hosted by the Clemson University Transportation Technology Transfer Service, T3 Service. The T3 Service has been operated by Clemson University's Civil Engineering Department and sponsored by the SCDOT and the FHWA since 1985. Information that can be found on this website includes the structure of the SCDOT Research program, all active SCDOT sponsored research studies, recently completed SCDOT sponsored research studies, current and past electronic copies of the Research Development and Technology Transfer (RD&T) Newsletter, and an electronic copy of SCDOT research problem statement form and instructions.
