Targeted Infusion Grant on Implementation of Superpave Technology into Transportation Courses in Undergraduate Civil Engineering Curriculum

摘要HRD 0928213北卡罗莱纳农业技术州立大学（NCA T）正在将Superpave技术纳入本科土木工程课程。目前，包括阿拉斯加和夏威夷在内的所有52个州公路局都采用了Superpave粘结剂系统。自2001年以来，北卡罗来纳州交通部要求所有沥青混合料都使用Superpave方法设计。然而，由于缺乏设备，NC A T州立大学一直在教授过时的方法（马歇尔设计）而不是Superpave方法。本项目正在购买Superpave沥青结合料试验设备，包括动态剪切流变仪、弯曲梁流变仪和直接拉伸试验装置。这些设备的增加提高了本科教育的质量，包括通过实验室经验发展学习技能。使用这种仪器是提高学生？了解Superpave技术和路面设计，增加学生人数。竞争力追求研究生学习在交通领域。这些改进正在支持北卡罗来纳州AT州立大学努力达到最高的教育标准。改进后的课程使学生在交通运输领域的就业和职业生涯中更具竞争力，并使NCA T能够为当地，州和国家就业市场培养知识渊博，高效的工程师。

ABSTRACT HRD 0928213North Carolina Agricultural & Technical State University (NCA&T) is incorporating Superpave Technology into the undergraduate civil engineering curriculum. Currently, the Superpave Binder system has been adopted by all of the 52 State Highway Agencies including those of Alaska and Hawaii. Since 2001, the North Carolina Department of Transportation has required all asphalt mixes be designed using the Superpave method. However, due to a lack of equipment, NC A&T State University has been teaching an outdated method (Marshall Design) instead of the Superpave method.This project is acquiring Superpave asphalt binder test equipment, including a Dynamic Shear Rheometer, a Bending Beam Rheometer and a Direct Tension Test Device. The addition of this equipment is improving the quality of undergraduate education, including development of learning skills through laboratory experience. The use of this instrumentation is enhancing students? understanding about Superpave technology and pavement design and increasing students? competitiveness to pursue graduate study in the field of transportation. These improvements are supporting North Carolina A&T State University in its effort to meet the highest educational standards. The improved curriculum places students in a more competitive position for employment and careers in the field of transportation and allows NCA&T to produce knowledgeable and effective engineers for the local, state, and national job markets.
