As the economic develop rapidly, pavement has played an important role in people’s life. To keep the citizen safe, the durability and safety of pavement have become a serious issue. Tack coat engineering is an indispensable step in pavement maintenance, if the tack coat isn’t performed well at the interlayer interface, it is easy to cause sliding problems between the pavement layers by insufficient shear strength, furthermore it may also cause pavement revealing and reflection crack. Nowadays, Taiwan pavement are focus on maintenance engineering. But due to the fact that crowded citizen issue the tack coat doesn’t have enough time to develop its strength. In order to shorten the working hours, it is often that the road maintenance engineering. aren’t cured and set. The objective of this study is to evaluate the performance of the tack coat quality on asphalt pavement using Interlayer Shear Strength Tester in laboratory, during this study scope including factors of interface bond strength, effects of interface bond strength in laboratory, the breaking and setting times, the air temperature and evaluate the effect of interface bond strength. The result for the break time and set time were found that for each material there was no significant difference in the shear strength test at four different curing times and two different temperatures. It can be understanding that the curing time and curing temperature of the tack coat in this experiment are both not significant factor. At the same time, this research also analyzes the shear strength and shear strain of the tack coat, considering the relationship between interface response modulus (K) and the calculation of the mechanical work of the tack coat. The shear and strain of the interlayer can be considered for a more comprehensive analysis for the tack coat. Moreover according to the analysis results, the bonding strength of emulsified asphalt is better than the cutback asphalt, and the use of modified emulsified asphalt can improve the bonding quality of the adhesive layer. |
