COMPOSITION FOR IMPROVING THE STABILITY AND OPERATIONAL PERFORMANCE AND REDUCING THE ENVIRONMENTAL IMPACT OF ASPHALT MIXES

摘要

The pitch mixing that can be used as the composition of additive, such as stone matrix pitch and porous asphalt, including mineral porcelain jasper or activator or amorphous silica, including pitch blend compositions. The asphalt is stable and meets according to the performance requirement of international standard. Less pitch is needed, is mixed under the pitch mixing ratio lower temperature, and it is lower to can be the mixing less time. The thus much economic, environmental protection of asphalt comprising the present composition, mixes than existing pitch.
