Abstract

The invention discloses a casting type asphalt isolating agent which comprises an isolating component, wherein the isolating component includes mineral oil and / or vegetable oil. The casting type asphalt isolating agent is characterized in that an antioxidizing component is added into the isolating component. In such an arranging manner according to the invention, the isolating agent with low surface energy can be acquired.

Description

technical field [0001] The invention relates to a castable asphalt mixture release agent, a preparation method and a paving method thereof. Background technique [0002] As a bridge deck paving material, pourable asphalt mixture has been used abroad for more than 100 years. The material has the characteristics of high mineral powder content (20-30%), high asphalt content (7-10%), high mixing temperature (220-230°C), etc. It has good water tightness, excellent fatigue and crack resistance, and easy deformation Good ability, strong integrity and other advantages. Therefore, it has been widely used in bridge deck pavement projects at home and abroad, such as Hong Kong-Zhuhai-Macao Bridge, Chongqing Caiyuanba Bridge, Xiamen-Zhangzhou Cross-sea Bridge, Ma'anshan Yangtze River Highway Bridge, etc. [0003] The pourable asphalt mixture is in a flowing state under the construction temperature, and no road roller is needed, only the pourable special paver is needed for paving and l...
