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.

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。拟议的五年研究，在研究目标概述如下，将集中在预测规则和模型的发展。生产沥青粘合剂的新材料和新技术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和制备阶段后的特性沥青粘结剂在高温下的性能研究b)研究现有的和潜在的沥青粘结剂在低温下的新特性及其与路面混合料低温抗裂性的关系。概述的研究项目将由研究生和实习学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。每个加拿大人都将受益于拟定的环境、卫生、技术和经济目标，这些目标将在这项研究方案中得到解答。为工业界、学术界和政府机构培养高素质人才也将是该研究计划的主要成果。
