A Study Of Bituminous Mixes With Natural Fibre (Sisal Fibre) By Experiment.

Advancement of country requires an improvement in part of transportation framework and its working. India is a nation with huge population with number of vehicles. Consistently greater necessity of roadway development and upkeep of street exist. Flexible pavement being generally utilized in India. Because of increment in number of vehicles traffic load and high high pressure from loaded or heavy vehicles causes pavement distresses. Hence this trouble desires to cope with and enhance the pavement performance by improvement of asphalt binder. Natural fibres have end up a studies recognition for scientist & engineering. The primary aim of this study is to determine the use of fibre available SISAL fibre in bituminous concrete as an additive. Bituminous blend, placed and compacted at high temperatures is called the hot mix of asphalt. Dense Grade Aggregate (DGM) is called HMA grade. Bituminous concrete (BC) was alluded to asphalt concrete. Pavement is susceptible to cracks, potholes, distress and continuous deformation. In this Study, SISAL fibre was used in bituminous mixes to examine the advantages of the use of natural fibres. Drain Down test and Marshall mix design testing on the mix were carried out. The mixing process and preparation of the aggregate was performed as per (IS-MORTH) specification. The different percentages of binder (4% -6%) and additive fiber (0% -0.8%) varied between total aggregates and stone dust as a filler. The optimal bitumen content (5%) was determined using the Marshall procedure. Similarly, Bituminous Concrete (BC) fibre content found to be (0.4 %).Samples for the mixture of bituminous concrete were made to find out their OBC and OFC, and then tested for the stability of Marshall. Drain the test down to evaluate the result of bituminous mix fibre addition. The results of the test show that the modification of sisal fibre in bitumen additives helps to increase its stability, durability and decrease air and flow volumes and prevent drain down. Evaluation by ultrasonic pulse velocity test helps checking clear picture and strength and cracks inside the mixes. Ultimately, fibre as an additive improves the properties like stability, force, durability and reduces bituminous concrete (BC) drainage.
