Evaluation of properties of fibre reinforced asphalt mix with copper slag as the filler

Rapid economic growth of countries requires continued expansion of the road network, which requires a huge volume of natural resources. Broken stones of coarse and finer sizes cause depletion of natural resources. On the Other hand, disposal of industrial waste is a great challenge. Hence, this research, the conventional filler (quarry dust) completely replaced by copper slag and glass fibre included in the asphalt mix varying from 0.1% to 0.4% by volume of asphalt mix with na incremente of 0.1%. The volumetric and mechanical properties investigated in the laboratory. The experimente results concluded that the asphalt mix with copper slag as filler and the fiber length of 8 mm with 0.2% by volume of mix exhibited optimum performance without compromising the volumetric properties.
