Project Background：
Volatile Organic Components (VOCs) and many other hazardous emissions will release from asphalt materials during heating process and normal service conditions. Such emissions will not only lead to environmental pollution, but also result in degradation of asphalt itself. This proposal believes that zeolite-based additive might give a chance to reduce the hazardous emissions and provide carbon sequestration, with no negative effect on the road performance of asphalt materials.
Aims & Goals:
1. Develop green asphalt materials with lower hazardous emissions and remark carbon sequestration behavior;
2. Discover the emissions absorption mechanism in asphalt, and carbon sequestration mechanism in pavement;
3. Synthesize nonmetallic additives for hazardous emission reduction and carbon sequestration in asphalt materials.
