INFLUENCE OF ACID MODIFICATION IN ASPHALT LAYER WHEN REINFORCED WITH GLASS FIBRE

The progressive traffic load intensity with its volume and tyre pressure showed a huge changes in structural stability of pavements and had resulted in pavement failure. Failure in structure is observed in  the form of rutting or fatigue, to overcome from these failure number of effort were made in the past to improve the structural properties of hot mix asphalt layer using additives, chemicals etc. In this study an attempt is made to evaluate the behaviour of acid modification with the inclusion of glass fibre. The modified binder has shown better performance in G*/sinδ and G*sinδ value when compared with conventional mix. The inclusion of glass fibre in modified mix showed a beneficial improvement on performance characteristics at an optimum of 2.7%.The progressive traffic load intensity with its volume and tyre pressure showed a huge changes in structural stability of pavements and had resulted in pavement failure.
