EXPERIMENTAL INVESTIGATION ON BITUMINOUS MIX USING COCONUT COIR
Journal Title: International Journal of Electronics, Communication & Instrumentation Engineering Research and Development (IJECIERD) - Year 2017, Vol 7, Issue 3
Abstract
A pavement structure can be divided in to two types flexible pavement or a rigid pavement based on its structural behavior. In India due to its advantages over rigid pavements and economy, flexible pavements are widely preferred here. Bituminous concrete mixes are the structurel layer used widely in Flexible pavements. The property of bituminous mixes can be enhanced by addition of fibres such as coir fibres. Fibre lengths were kept i.e. 15mm and used at the rate of 0.3%, 0.5% and 0.7% by weight of mix. In this project, Marshall method of mix design was taken in to consideration for the mixes and the project studies the stability of coir as a reinforcing material in bituminous mixes. The optimum bitumen content and fiber content is analysed for the coir fiber and their performances is determined. An optimum bitumen content of 5%, optimum fibre content of 0.3% and fibre length of 15mm was obtained after analysis. On doing a study on the Marshall parameters, it is found that the augmentation of coir fibre to SDBC mix contributes significantly in enhancing the performance of the mix.
