Moisture Susceptibility on Asphalt Mix and the Effect of AntiStripping Additives
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2016, Vol 4, Issue 12
Abstract
The damage due to moisture can be result in asphalt pavements either due to stripping or the softening of asphalt, both of which result in loss of ability to resist traffic- induced stresses which is mainly occur due to the loss or destruction of bond between the aggregate and the asphalt. This study is aimed to determine the effect of moisture on different graded bitumen mixture i:e open graded mixture and dense graded mixture and the effect of anti-stripping agent(lime) in hot mix asphalt(HMA). Moisture susceptibility of asphalt mixture can be determined by different tests indirect tensile strength test, Retained Marshall stability value and boiling water test with varying the percentage of lime content from 0% to 2.5%.The results indicates that the addition of hydrated lime increases the moisture resistance value to some extent and also provide larger strength as compare to the other mixes without addition of lime and more over the dense graded mix provide more effective value than open graded mixes.
