ANJANEYULU ABSTRACT: Surface cracking of pavements decreases its fatigue response. The inclusion of glass fibre in bituminou

2、s mixes increases the fatigue life of pavements. In the current investigation E glass fibre is mixed with the bituminous mixes and Marshall Stability test was conducted. The optimum bitumen content and flow value were evaluated. The influence of this glass fibre on durability and the engineering pro

3、perties of semi dense bituminous concrete such as stability, flow, air voids in the mix, voids in mineral aggregates and voids filled with bitumen are presented in this paper. The stability values increased by as much as 32%. KEYWORDS: Fibre Glass, Bituminous Mixes, Marshall Stability Test, Stabilit

4、y, Flow Value 1. INTRODUCTION The low tensile strength of bituminous mixes causes the pavement subjected to repeated loading to crack. The propagated cracks develop distress symptoms like raveling, undulations, rutting, cracking, bleeding, shoving and potholing of bituminous surfacing. The high traf

5、fic intensity of commercial vehicles also compounds this problem. Hence, to improve the performance of the pavements, reinforcements and additives are added to the bituminous mixes. Therefore, there arises a necessity to evaluate the optimum fibre content and the type of fibre. The fibres placed in

6、the bituminous mix are homogeneously dispersed and act as stress absorbing layers. In the recent past, cotton, metal wire and asbestos were used. Cotton is degradable and cannot be used as long term reinforcement; metal wire rusts when water penetrates. Asbestos poses health hazard. This automatically leads to the choice of glass fibre. Transportation is the lifeline of any nations economy and hence improving the perfor
