Development of asphalt solutions for paving applications with optimum environmental and engineering properties

为了满足对高质量路面材料日益增长的需求，现代沥青路面依靠改性技术来改善其工程性能。目前最成功的改性技术是通过大分子材料（聚合物）的掺入，但也有其他类型的添加剂。通过反复试验，设计了工程沥青路面的改性工艺。

To address the ever-increasing demands on high quality paving materials, modern asphalt pavements rely on the modification technologies to improve their engineering properties. The most successful modification technology nowadays is through incorporation of macromolecular materials (polymers), but also other types of additives. The modification technologies for production of engineered asphalts pavements are designed by trial and error. The proposed five-year research, outlined in the research objectives below, will be centered on the development of predictive rules and models. 1. New materials and technologies for production of asphalt binders a) materials and techniques - design and production of selected modified asphalts b) characterization of modified asphalts during and after their preparation phase 2. Characterization of conventional, air-blown, and modified asphalt binders in paving mixes a) characterization of asphalt binders at high service temperatures, selection of tests and parameters best correlating with their performance in paving mixes b) investigation of available and potential new characterization of asphalt binders at low service temperatures and their correlation with the low temperature cracking resistance of paving mixes The outlined research program will be performed by graduate and internship students with support by the professional staff in the topnotch laboratory with state-of-the-art equipment. Every Canadian will benefit from the formulated environmental, health, technical and economic goals which will be answered in this research program. The training of highly qualified personnel for industry, academia and government bodies will also be the main outcome of the research program.
