Welcome to the Center for Georgia Aggregates Research (CGAR). CGAR was established in 2010 and serves the industry and state DOT as a forum for research, consulting, and discussion where civil, construction, pavement and geotechnical engineering stakeholders can seek answers. The center’s mission is enhanced by the active participation of state DOT and federal agency representatives in formulating our research and consulting programs, and overseeing its accomplishment. Through seminar, research and consulting reports, and newsletters, CGAR is putting the most practical and state-of-art technology into the hands of aggregate industry, state and federal agencies, ensuring that the resources are used in the most efficient manner.

The service contract from CGAR has been signed by SPSU and Georgia Department of Transportation (GDOT).

Starting May 2012, the funded special research study has focused on the structural analysis of Georgia pavements containing aggregate base layer in the state of Georgia.
The CGAR has been playing a significant role to accurately identify the pavement structure and provide meaningful analyses of Georgia pavements for GDOT.
