Abstract

Flexible pavement is a multilayered structure constructed in layers. In order to ensure proper bonding such that a pavement behaved monolithically, tack coat is often applied. The developed pavement interface bond strength is therefore paramount in governing the overall performance of pavement serviceability. The present work reviews the current state of pavement interface bond strength quantification mechanisms, and the devices developed based on the mechanism. Related accessible literatures are collected and analyzed to compile the characteristics of each bond testing devices and evaluated for the capabilities and test performance. The investigation reveals 3 testing mechanisms incorporating shearing (pushing), tensile (pulling) and torsioning (twisting). However, shearing test seems to be the most popular device adopted to investigate the bond strength between two interfaces in contact, utterly due to the simplicity of the test setup. For tensile mechanism, the developed devices are generally portable and are mostly used to examine the tack coat quality. Finally, the device with torsional mechanism is not so popular as compared to the aforementioned mechanism. Nonetheless, it is developing steadily with the continuous research
