Abstract
Exposure to natural elements such as ultraviolet radiation, moisture, acids and saline solutions produces a succession of chemical changes in the composition of asphalt, especially in the oxidation process leading to the loss of elasticity and adhesive properties. The presented products are made on the basis of bitumen, modified with a polymer compound, with the purpose of extending the life of the road by at least 3 to 5 years from application. The materials prevent surface oxidation and surface decomposition by blocking the appearance of microcracks, caused by water, erosion and road damage. The products are easy to apply and offer an economical solution for road maintenance.
