Description

technical field [0001] The invention belongs to the technical field of road engineering materials, and in particular relates to a method for preparing prefabricated drainage channels by regenerating asphalt pavement surface layer milling materials. Background technique [0002] During the long-term use of asphalt pavement, due to the combined effects of heavy-duty traffic, climate and environment, its service performance will show attenuation, resulting in the indicators of functional and structural performance of asphalt pavement in some road sections failing to meet the use requirements. Remodeling and maintenance. Due to the limitation of the elevation of the road surface, the major and medium repair projects of the road surface usually adopt the method of milling the original road surface and then re-paving, resulting in a large amount of waste asphalt milling materials. [0003] If the waste milling material is discarded directly, it will not only bring environmental p...
