中文摘要： VOC(Volatile Organic Compounds)是挥发性有机化合物的简称，具有挥发性高、浓度低、活性强等特点。VOC自身及其所衍生的光化学污染，会危害生命健康与农作物生长，已成为世界性公害。长期以来，国内外主要关注的是来自装饰材料、生物源与机动车尾气等的VOC及其危害，而对广泛应用于道路工程、建筑防水等领域的沥青所产生的VOC未引起足够的重视。本项目拟针对不同来源、不同类型的沥青，研究其在不同光照波长与强度、时间等条件下VOC的释放情况，根据其VOC释放量及其规律特点，建立沥青VOC释放模型，探讨沥青VOC释放与其组成、结构、性能的相关性，揭示沥青VOC释放机理，分析沥青VOC对环境和人体健康的危害，探讨具有低VOC释放的沥青组成结构特点和释放环境条件特点，研究沥青VOC的抑制方法。本项目成果将为开发绿色环保型沥青以及提高沥青和沥青材料的使用性能等提供理论指导。

英文摘要： VOC (Volatile Organic Compounds) refers to volatile organic compounds with the properties of high volatility, low concentration, strong activity, and so on. Photochemical pollution form VOC and its derived materials can endanger life and health as well as the growth of crops, which has become one of the worldwide public hazard. Over the years, the main concerns in VOC sources in the world are coming from decorative materials, biological source, and motor vehicle exhaust. However, no enough attention has been paid on the VOC from asphalt materials being widely used in road engineering and construction waterproof. This project intends to study the VOC emissions from asphalt with different sources and different types in term of varying environmental conditions ( e.g. different light wavelength, light intensity, light duration). Based on the emission amount and characteristics of asphalt VOC, its releasing model will be developed. In addition, the effect of VOC emission on asphalt composition, structure and performance will be explored, meanwhile, the mechanism of asphalt VOC emission will be revealed.The effect of asphalt VOC on environment,life and health will be analyzed. The characteristics and related environmental impacts of asphalt with low VOC emission will also be investigated. Furthermore, the methods of c
