A Method of Fatigue Testing of Concrete Highway Joint Sealants in Shear

CODEN: JTEVAB

Abstract

A simple test method has been developed to simulate the movement of a typical transverse contraction joint used in joining concrete highway pavement sections constructed without dowels. The test apparatus enables the effects of temperature, joint size, and pavement deflection on the performance of the sealant to be evaluated in joints subjected to large differential movements. Testing at temperatures below and above ambient is possible by incorporating an environmental chamber. A detailed description of the fatigue test apparatus and specimen preparation is provided. Typical results of tests conducted at room temperature, −40°C, and +40°C are presented as well as the results of thermal cycling.
