| Popis: | In order to prepare a kind of high-performance asphalt pavement pit repair material and extend the service life of the road, this paper starts from the microscopic view of the raw materials, uses infrared spectrum, four component analysis method, lying drop method, column wick technology principle, etc. to select the raw materials and determine the initial amount of the cold patching asphalt mixture, and optimizes the formula through the orthogonal test design and adhesion, cohesion, initial stage strength, later strength, residual stability, and other performance indexes, and determines the final formula of cold patching asphalt mixture as follows: the design porosity is 15 ± 0.5%, compatibilizer is 2.5%, linear SBS modifier is 5%, tackifier is 4%, antistripping agent is 3.5%, and the dosage of diluent D should be determined according to the ambient temperature. The results show that the performance of the self-made cold patching asphalt mixture is good verified by adhesion grade, strength, high temperature stability, water stability, and other road performance. |
