Abstract
Abstract An elastomeric pavement repair composition for pavement failure and a method of preparation thereof comprising of paving grade asphalt and rubber. The asphalt is heated to an elevated temperature and the rubber is combined therewith. The resulting composition is mixed to form a hot jellied composition which can be applied to cracked or distressed pavements to repair the same.
