Analysis of the Adhesiveness Between the Layers of Bituminous Pavement

Abstract

This study looks at the impact of tack coatings on the performance and longevity of flexible pavements, as well as the significance of layer adhesion in bituminous pavements generally. Research shows that problems like delamination, slippage, and top-down splitting can weaken pavements, therefore it's important to bond materials properly. This study compares and analyses, by experimental testing, the effectiveness of different tack coat types (CRS-1 and CMS-2) and application rates in strengthening interlayer bonding. According to the findings, CRS-1 is more effective than CMS-2, and an application rate of 0.30 kg/m² is recommended for achieving maximal shear strength. These findings can be used to improve pavement design and decrease the chances of early failures, which in turn increases the lifespan of roadways. The report goes on to suggest more studies to test these results in different real-world settings and environmental factors.
