| 摘要： | This study is aimed at arriving the optimum dosage and study the performance of glass fibres in bituminous mixes. The Aggregates bound with bitumen are conventionally used all over the world in construction and maintenance of flexible pavements. It is thought that with the help of additives is one of the approaches to improve performance of flexible pavements. Here glass fibres have been used to improve the performance of asphalt mixtures against permanent deformation as they possess inherent compatibility with asphalt and excellent mechanical properties. The Glass fibre of different length 6 mm, 8 mm, 10 mm and 12 mm at various percentage (0.2, 0.3 and 0.4% by weight of Aggregate) were added individually to the aggregates and Marshall specimens were prepared using VG 40 Bitumen (after finding the optimum binder content) to arrive at the optimum dosage of Glass fibre in Bituminous mixes. Various performance tests were conducted to analyse the effect of Glass fibre on Bituminous mixes (i.e.,) Bituminous concrete-Grade Ⅱ. In this study, it was found that the use of glass fibres in bituminous mix of length 8 mm and 0.3% by weight of aggregates with an optimum binder content of 5.73% by weight of aggregates have shown as an optimum dosage to exhibit better results than the Conventional Bituminous mix. The study compares the performance test results of Glass Fibre Bituminous mix with Conventional Bituminous mix which made from the VG-40 bitumen. |
