| Abstract: | Through the heavy repair practice of pavement on Quzhou section of No. 320 State Road, the preparation, mixture design, mixing, transportation, paving, roller process and quality control points of TLA modified asphalt are expatiated on, indicating that TLA modified asphalt has good low-temperature and high-temperature resistance performance. According to the practical experiences of the engineering, it is educed that the preparation of modified asphalt and the temperature control of all aspects of construction are points of construction quality control, and the material is suitable for use in the area with large traffic volume, heavy duty, hot summer and cold winter. |
