| Abstract: | Water damage of asphalt pavements due to insufficient moisture susceptibility is not only one of the major types of early destruction but also one of the major obstacles to applying domestic heavy duty road asphalt to freeway. The paper roundly studies the moisture susceptibility and the factors which affecting it. The change rule of moisture susceptibility when mineral aggregate,aggregate gradation,air voids and asphalt ingredients vary in hot mixed asphalt (HMA),exploring the physicochemical characterizat... |
