PERFORMANCE EVOLUTION OF BITUMUNOUS MIXES USING COIR GEOTEXTILES

The present study is used to find the strength of bitumen. From this we conclude that the increase in the strength of bitumen by varying different proportions of coir fibre. For this we find the properties of aggregates and for bitumen property we conduct the penetration test, ductility test, softening ball point, Flash and fire test and marshal stability test. We use aggregates using MORTH table, bitumen and filler material and we find flow, stability and bulk density. For this we use the proportions of coir fiber has 2%, 4% and 6%. After comparing the results we find the optimum binder content and we find the stability and flow value.
