USE OF SAND ASPHALT IN HIGHWAY CONSTRUCTION
Sand asphalt construction is being utilized by states in the Coastal Plain area of the Southeastern United States to alleviate the scarcity of high quality coarse aggregates. The paper summarizes current State Highway Department sand asphalt practice in the Coastal Plain. Representative local sands were selected from the state of Georgia. Tests were performed to determine aggregate characteristics, mix design, and the stress deformation properties of the sand asphalt mixes. An elastic layered analysis was used to determine the types of pavement sections in which sand asphalt could be successfully substituted for asphalt concrete. Finally, economic advantages of sand asphalt are discussed.
