Engineering - Civil (54) Project SummaryIn order to implement the Superpave asphalt mixture design system properly, and realize its full benefit through improved performance of pavements, it must be ensured that mix production, laydown and compaction in field projects are controlled to maintain compliance with Superpave specification. However, results of recent research regarding improved mix design systems and quality control techniques have remained largely unknown to undergraduate students who will be building and maintaining the pavements in near future. At present, there is a severe lack of opportunity for the undergraduate students to gain field experience and learn application of statistical concepts in quality control in asphalt technology. The objectives of this project are to provide the undergraduate students tools for field experience in asphalt pavement construction, including quality control techniques, and to teach the concepts of statistical quality control through analysis of real time quality control test data. A thorough knowledge of all aspects of asphalt mix design and construction, and an experience of using real time data for statistical quality control is needed to understand the link between design and construction, and identify potential problems during production, construction, and life of the pavement. The equipment requested will be used with the existing equipment to provide an all around well-balanced coursework, which integrates design, production, laydown and compaction of asphalt mixtures. Three pieces of equipment will be used by the students: the pavement quality indicator for measuring in-place density during construction, the rapid triaxial device for evaluating mixes during production, and portable computers with statistical software for analyzing real time quality control data. The undergraduate students will use the in-place measurements to gain experience in operation of equipment, understand techniques of proper interpretation of test results and making decisions based on test results.

工程-土木（54）项目总结为了正确实施Superpave沥青混合料设计系统，并通过改善路面性能实现其全部效益，必须确保现场项目中的混合料生产、铺设和压实得到控制，以保持符合Superpave规范。然而，最近的研究结果，关于改进的混合设计系统和质量控制技术仍然在很大程度上未知的本科生谁将在不久的将来建设和维护路面。目前，本科生在沥青技术质量控制中缺乏现场实践经验和学习统计概念应用的机会。本计画的目标是提供本科生在沥青路面施工中的实地经验工具，包括质量控制技术，并透过分析真实的时间质量控制测试资料，教授统计质量控制的概念。需要对沥青混合料设计和施工的各个方面有透彻的了解，并有使用真实的时间数据进行统计质量控制的经验，以了解设计和施工之间的联系，并识别路面生产、施工和寿命期间的潜在问题。所要求的设备将与现有设备一起使用，以提供全面平衡的课程，将沥青混合料的设计、生产、铺设和压实整合在一起。学生将使用三种设备：用于测量施工过程中现场密度的路面质量指示器，用于评估生产过程中混合料的快速三轴设备，以及带有统计软件的便携式计算机，用于分析真实的时间质量控制数据。本科生将使用现场测量获得设备操作经验，了解正确解释测试结果的技术，并根据测试结果做出决策。
