This Natural material are limited in nature due to which quantity of natural materials are decreasing and its cost is increasing.Concerned about this,Engineers are looking at alternative material for highway construction by which quality of road is increased with low cost.In present scenario, the use of automobile is significantly increased due to which the quantity of waste and scrap also increased. Keeping in mind , the need for use of bulk quantity of solid waste in India,it was thought to test these materials and develope specifications so that we can enhance the use of waste tires in road making from which higher economic returns may be possible.Crumb rubber which is obtained from waste tyres can be , where we melt the crumb rubber with bitumen and mixing it with various percentage of CR.In this paper ,an attempt is made to know what percentage incorporation of crumb rubber to bitumen , upgrade the strength and durability of pavement.To know the quantity of rubber replacement in pavement and to know the variations in strength parameters by conducting different tests. The use of waste tyres in construction of road pavement helps to reduce noise pollution occurs during heavy traffic due to friction and so on. Materials that are use is Bitumen VG-30,asphalt and tyres rubber crumb.Methodology to achieve this project is marshal stability test and common test that is to be done in aggregate and asphalt and expected outcomes will be properties of bitumen such as softening point ,flash point ,fire point increases with addition of waste crumb rubber. Ductility value decreases with increase in percentage of modifier (rubber pieces). This modified bituminous mix can bring real benefits to highway construction, maintenance in terms of better and longer lasting roads and savings in total road life casting.

AC – Asphalt Concrete , CRMB - crumb rubber modified bitumen , CR – Crumb Rubber.
