Overview of Potential Application of Pineapple Leaves Fibre (PALF) in Asphalt Mixture Focusing on Fatigue Resistance
Keywords:Pineapple Leaves Fibre (PALF), Asphalt mixture, Fatigue cracking
Asphalt mixture has played an important role in the transportation system throughout the world. Even if asphalt mixture are well designed and constructed, they may require proper maintenance to avoid some typical of asphalt mixture distresses occur due to traffic loading, environment or climate influences and material quality problems. Fatigue cracking is one of the major modes of failures in asphalt pavement. Modifying asphalt mixture using fibres for superior performance is not a new phenomenon. PALF is one of the natural fibres which have good potential in asphalt pavement. However, study focus on pineapple leaves fibre (PALF) in highway engineering is very minimum. The main objective of this overview are to investigate fatigue resistance of asphalt pavement modified with fibres and their scopes of study. In addition, Marshall Stability and Indirect Tensile Strength test of asphalt mixture performance with PALF also studied from the previous study in order to achieve these review study objectives. PALF has the potential to be a new supply of raw materials for industry, as well as a potential alternative for costly and nonrenewable synthetic fibres. In conclusion, this review article has explored the basic information of PALF and compared the physical, chemical and mechanical properties with other natural fibres in modifying in asphalt mixture. In addition, future research towards the use of PALF experimental procedure in laboratory also needed in order to prove the potential of PALF in asphalt mixture and also to determine the optimum percentage of PALF to be apply in asphalt mixture is encouraged.
