Mixing machine can be divided into continuous and batch two categories. After the preparation process Henan asphalt wholesale, past the first sand and gravel multi-use dry heat, and then with hot asphalt and cold mineral powder mixing. And the development of a wet marinated with hot asphalt aggregate, and then heated mix of methods to eliminate fly ash aggregate in heating and drying. When using the latter process, to prevent residual moisture mix asphalt concrete impact on life, preferably while using Antistripping to enhance water resistance. The mid-1980s China began building the highway asphalt manufacturers of Inner Mongolia, from the formal point of view the structure of the surface layer of asphalt: Ⅰ type of asphalt concrete, 3% to 6% porosity, permeability is small, durability, friction coefficient of the surface layer able to meet the requirements, but the surface texture depth smaller Ningxia asphalt manufacturers, can not meet the requirements. Asphalt Type Ⅱ 6% to 10% porosity, surface structure depth, strong resistance to deformation capacity, but its water permeability, durability is poor. To solve the skid resistance of asphalt surface layer (especially the depth of the surface layer in the structure is large, but also has good form waterproof structure), multi-stone asphalt concrete surface layer is to study and use. _ Quote _ asphalt bitumen Anhui, Shandong Zhuoqun (view) provided by Material Co., Ltd.
