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

为了满足人们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掺入高分子材料（聚合物），但也包括其他类型的添加剂。工程沥青路面生产的改性技术是通过试验和错误设计的。拟议的五年研究，在下面的研究目标中概述，将集中在预测规则和模型的开发上。生产沥青粘合剂的新材料和技术a）材料和技术-选定改性沥青的设计和生产b）改性沥青在制备阶段期间和之后的表征2.铺路混合物中常规、吹气和改性沥青粘合剂的表征a）沥青粘合剂在高使用温度下的表征，选择与铺路混合料性能最相关的试验和参数b）研究沥青结合料在低使用温度下可用的和潜在的新特性及其与铺路混合料低温抗裂性的相关性概述的研究计划将是由研究生和实习生在拥有最先进设备的一流实验室的专业人员的支持下进行。每一个加拿大人都将受益于制定的环境、健康、技术和经济目标，这些目标将在本研究计划中得到回答。为工业界、学术界和政府机构培养高素质人才也将是研究计划的主要成果。

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 bindersa) materials and techniques - design and production of selected modified asphaltsb) characterization of modified asphalts during and after their preparation phase2. Characterization of conventional, air-blown, and modified asphalt binders in paving mixesa) characterization of asphalt binders at high service temperatures, selection of tests and parameters best correlating with their performance in paving mixesb) 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 mixesThe 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.
