ECONOCRETE SUBBASE: A NEW CONCEPT IN PAVEMENT STRUCTURES

This portland cement concrete made with locally available crusher run or reclaimed aggregate, which is specifically designed to satisfy the requirements of each application and environment and provide an economical pavement structure, is used for composite pavements, subbases, shoulders, street pavements and parking lots. A major application is in subbases where it produces resistence to erosion and to the attack of deicing salts. Econocrete subbases are placed by slipform pavers with automatic grade control. Construction details are briefly outlined. On a paving project, the fine grading of the soil subgrade is electronically controlled from a stringline. Comments are made relating to mix designs, and a field application (subbase on an interchange of interstate Highway 77 in South Carolina) is described.
