Engineering - Civil (54)The performance of an asphalt pavement depends on various factors, the most important of which is how well the mix was designed against various environmental and traffic loads expected to act on it during its service life. In private industry as well as in governmental agencies, the use of superior performing hot mix asphalt, known as Superpave, has achieved widespread use resulting in a high demand for individuals with Superpave design experience. One of the integral parts of the Superpave system is a newly developed mix design methodology that has proven to be far superior when compared to traditional mix design methods. In this project, two existing undergraduate civil engineering courses are being modified to include modules on Superpave theory, design, and testing. Hands-on laboratory experiences are being developed and evaluated for learning effectiveness through this project. The modules are being inserted in two compulsory courses at the institution, ensuring that all civil engineering students learn about the Superpave technology to better prepare them for their engineering careers.

沥青路面的性能取决于各种因素，其中最重要的是在其使用寿命期间，混合料的设计是否能很好地抵御各种环境和交通荷载的影响。在私人工业和政府机构中，使用高性能热混合沥青，被称为Superpave，已经实现了广泛的使用，导致对具有Superpave设计经验的个人的高需求。Superpave系统的一个组成部分是一种新开发的混合设计方法，与传统的混合设计方法相比，它已被证明是远远优越的。在这个项目中，现有的两门本科土木工程课程被修改为包括Superpave理论、设计和测试模块。通过这个项目，正在开发和评估实践实验室经验，以提高学习效果。这些模块被插入到该机构的两门必修课中，以确保所有土木工程专业的学生都能了解Superpave技术，从而更好地为他们的工程职业生涯做好准备。
