Preliminary performance assessment of asphalt concrete with paint sludge from automotive industries

摘要: Application of paints by spraying, extensively used in the automotive industry, represents a significant source solid waste. The generation paint sludge, from 2.5 to 5 kg for each painted car, is becoming an important problem management and environmental point view owing its huge volumes hazardous characteristics. In this research laboratory investigation was carried out order evaluate performance asphalt concrete mixtures obtained using binders modified with sludge (10% on base bitumen) comparison traditional mixtures. between two materials taking into account volumetric mechanical Outcomes tests demonstrated that addition does not alter mixture significantly. particular, has no effect properties, it increases stiffness modulus but change resistance permanent deformation.
