Development and Research of Steel Bridge Surface Asphalt Technique for Large Span Suspension Bridge

摘要

This artile deals with the development and research of the high behaveior of the compound modified asphalt SMA mixture shall be chosen for the main research of the high behavior, the component and behavior study of the SMA mixtures, the materials behavior inspection and choice of the proof-water glue course, and the large-scale annu lar-way analogy test, the paving structure should be chosen and optimized, the fatigue life of the different paving structure combination should be analyzed, and the execution scheme the bridge surface paving of the modified asphalt SMA mixtures on the orthotropic steel bridge surface plate for Humen large bridge should be finally determined.
