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.

为了满足对高质量铺路材料的不断增长的要求，现代沥青路面依赖于修改技术来改善其工程特性。如今，最成功的修改技术是通过合并大分子材料（聚合物），也是其他类型的添加剂。用于生产工程沥青路面的修改技术是通过反复试验设计的。在下面的研究目标中概述的拟议的五年研究将集中在预测规则和模型的开发上。1。用于生产沥青Bindersa）材料和技术的新材料和技术 - 在制备期间和之后的修饰沥青的设计和生产。铺路混合物中常规，吹气和修饰的沥青粘合剂的表征）表征高服务温度下沥青粘合剂的表征，测试和参数的选择，最佳的与其在铺路中的效果相关联，其可用的调查和潜在的降低温度的粉碎型在较低温度的差异型在较低温度上的表征，并潜在由毕业生和实习生在Topnotch实验室的专业人员提供的支持下，并提供了最先进的设备。每个加拿大人都将从该研究计划中回答的环境，健康，技术和经济目标中受益。培训高素质的行业，学术界和政府机构的培训也将是研究计划的主要结果。
