Without regular asphalt maintenance, water, sun, air and traffic cause asphalt to erode. Although a solid foundation, quality asphalt mix, and professional installation can increase the lifespan of your pavement, it requires routine maintenance. At Bituminous Roadways, Inc., we want to preserve and extend the life of your pavement.
