RECENT DEVELOPMENTS IN STRENGTH TESTING FOR CONCRETE PAVEMENT CONSTRUCTION. IN: RECENT DEVELOPMENTS IN THE DESIGN AND SPECIFICATION OF CONCRETE PAVEMENT SYSTEMS (SP-181)

The tensile strength used in the design of concrete structures, such as concrete pavement systems, has typically been determined based on small test specimens such as split tension cylinders and bending beams. It is well known that strength values obtained from different specimens can be largely different. The paper questions the applicability of strength values obtained from conventional specimens to an actual structure. This deficiency is encompassed within effects of specimen or structure size and geometry on the strength. Since fracture parameters can be used to determine the tensile strength of concrete structures, a simplified tension test method, based on the size effect law, is presented in this paper to determine fracture parameters. Cylindrical specimens are incorporated in the proposed method since such specimens have the advantage of being easily cast or cored. Special emphasis is given to concrete pavement systems where tensile strength is particularly important since most distresses in concrete pavements are due to tension-induced cracking.
