Title: PRELIMINARY REPORT OF AN APPARATUS FOR THE TESTING OF ASPHALTIC CONCRETE DIAPHRAGMS
Abstract: This report is concerned primarily with the design of a machine for testing asphaltic concrete diaphragms subjected to repetitive flexures. Procedures and data of the fabrication and testing of specimens approximately 18 in (46 cm) in diameter are presented. The apparatus, called a deflectometer, was evaluated by testing a coarse sheet asphalt mixture. Several variables that are believed to affect the endurance of a specimen to repeated flexures were investigated, and the resulting effects were compared with the number of load applications to cause failure.
