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

北卡罗来纳农业技术州立大学（NCA&amp；T）将Superpave Technology纳入本科土木工程课程。目前，Superpave Binder系统已被包括阿拉斯加和夏威夷在内的所有52个州公路机构采用。自2001年以来，北卡罗来纳州交通部要求所有沥青混合料都采用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一种过时的方法（Marshall Design），而不是Superpave方法。本项目正在采购Superpave沥青粘结剂试验设备，包括一台动态剪切流变仪、一台弯曲梁流变仪和一台直接拉伸试验装置。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。这种仪器的使用提高了学生的能力。对Superpave技术和路面设计的理解和增加学生？在交通运输领域攻读研究生的竞争力。这些改进正在支持北卡罗来纳农工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处于更具竞争力的地位，并使nca&； T能够为当地、州和全国的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 However, due to a lack of equipment, NC A&T State University has been teaching an outdated method (Marshall Design) instead of the Superpave method.This project is acquiring Superpave asphalt binder test equipment, including a Dynamic Shear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.
