In order to develop the multiple reuse ways of waste, the Environment Protection Administration promoted the waste tire rubber asphalt project, and introduced a complete set of mobile rubber asphalt blending facility, to get the achievement of finishing the paving of National Highway No. 1, No. 61 Highway etc. The research and development thinking of this project is to develop the diversified technology of rubber asphalt material, improve the convenience of supply, and consult the development experiences of the United States, Mainland China etc. It is recommended to establish the rubber asphalt factory, to supply the rubber asphalt product to the asphalt factory. It will be able to increase the use convenience and accelerate the promotion and application. Therefore, the work items of this project are mainly divided into 3 parts: (1) Collect the application practice validation of waste tire rubber asphalt factory, in order to set up the reference basis of domestic practical application: Refer to the practical technology and application experiences of foreign waste tire rubber asphalt factories, in order to get approximate homogeneous and stable rubber asphalt oil through controlling the crumb rubber category and content, shearing speed of blending, blending temperature and chemical treatment etc. (2) Carry on the willing inquiry for the setup of rubber asphalt factory by the domestic industry, in order to create the cooperative platform of production and research. (3) Through the promotion platform of rubber asphalt factories, to carry on the domestic factory construction technology assessment, understand the promotion problems and countermeasures, in order to propose the blueprint of factory construction: The promotion of factory construction can be divided into two stages. One is to cooperate with the production of modified asphalt factory. Produce the factorized rubber asphalt through the modified asphalt technology, to achieve the validated stage of suitable rubber asphalt pavement.
