Study on the Method of Heating Asphalt with Solar Energy

Abstract:

The color of the asphalt is close to black, it has the good ability of absorbing the solar energy. Road asphalt are solid or half a solid state at normal temperature, it must be reduced the asphalt viscosity to a certain range before used it. The main method of reducing the viscosity of asphalt is heating it. Because of the high temperature of the construction of asphalt, the traditional method on the asphalt heating is electrical heating which needs to consume large amounts of energy. Solar energy is huge and clean energy, which can save large of energy on the asphalt heating. This paper expounds on the solar heating principle, as well as designs the solar heating device to research the energy-saving method on the heating of road asphalt.
