The Effect of Compaction Effort on Fatigue Performance of Cold Emulsified Bitumen Mixes with Reclaimed Asphalt Pavement
Keywords:Compaction Effort, Reclaimed Asphalt Pavement, Indirect Tensile Strength
During the service period, flexible pavements tends to produce series of distresses, such as rutting, cracking, pothole, etc. When the distresses are severe, the best method is to recycle the distressed layer using stabilizers like emulsified asphalt or some additives and that layer can be used as a base\sub base or surface course based on the purpose. The milled material is known as Reclaimed Asphalt Pavement (RAP) and the application of emulsified asphalt comes under cold mix asphalt technologies. This can help to create a cleaner production including lesser usage of natural aggregates and lower carbon emissions. Compaction is one of the significant factors in order to prevent premature failures and for better performance of the mix. A properly compacted base develops adequate density and strength; the present study investigated the influence of compaction effort on the fatigue performance of Emulsified Asphalt Treated Bases (EATB). The performance indicators include Indirect Tensile Strength (ITS), Resilient Modulus (MR), and fatigue characteristics. Finally, the study developed the models between ITS and MR for different fluid contents.
