Development and Implementation of Digital Specimen and Digital Tester Technique for Infrastructure Materials

0438480这个奖项授予路易斯安那州立大学，以支持下面描述的活动36个月。合作伙伴包括路易斯安那州立大学(牵头机构)、南方大学(历史上的黑人学院和大学-HBCU)、路易斯安那州交通研究中心、国家沥青技术中心、国家沥青路面协会、联邦公路管理局、Barriere建筑公司和辉固地球科学公司。主要目标是开发多功能数字标本和数字测试技术，在联邦公路管理局特纳-费尔班克研究中心和其他合作伙伴机构实施这些技术，将新开发的技术商业化，为本科生和研究生工程师开发培训课程为沥青铺装技师协会举办研讨会，向执业工程师推广有关技术的获取和使用，并寻求将该技术应用于建造业的其他材料。潜在的经济影响拟议的创新将为建筑材料的设计创造一个基于计算机的测试和评估系统，使其在使用中的耐久性更长，并降低生命周期成本。一旦该方法被完全开发，就可以很容易地将其修改为其他材料技术。该项目的智力优势包括通过减少测试样本数量来增强当前沥青材料配合比设计的实践，增强沥青材料配合比设计以优化使用中材料的工程性能，降低建筑行业使用有缺陷材料的可能性，以及了解建筑材料的寿命耐久性。该活动的更广泛影响集中在以最少的测试和认证成本加强建筑材料的设计，教育和培训未来的建筑工程师，增加代表不足的群体参与研究、教育和专业工程实践，对国家基础设施的经济和社会影响。

0438480TumayThis award is to Louisiana State University to support the activity described below for 36 months. The proposal was submitted in response to the Partnerships for Innovation Program Solicitation (NSF-04556).PartnersThe partners include Louisiana State University (Lead Institution), Southern University (historically black college and university-HBCU), Louisiana Transportation Research Center, National Center of Asphalt Technology, National Asphalt Pavement Association, Federal Highway Administration, Barriere Construction Company, and Fugro Geosciences.The primary objectives are to develop multiple functional digital specimen and digital test techniques, to implement these techniques at Federal Highway Administration Turner-Fairbank Research Center as wells as at the other partners facilities, to commercialize the newly-developed techniques, to develop a training course for undergraduate and graduate engineers, to conduct seminars for Association of Asphalt Paving Technologists to promote acquisition and utilization of the techniques to practicing engineers, and to seek use of the technology in other materials in the construction industry.Potential Economic ImpactThe proposed innovations will create a computer-based testing and evaluation system for design of construction materials with a longer durability in-service and a reduced life-cycle cost. Once the methodology has been fully developed, it can easily be modified for other materials technologies.The intellectual merit of the project includes enhancing current practice in mix design for asphalt materials be reducing the number of specimens to be tested, enhancing the mix design for asphalt materials to optimize the engineering properties of the material in use, reducing the probability of having faulty materials being used in the construction industry, and understanding the lifetime durability of construction materials.The broader impacts of the activity concentrate on enhancing the design of construction materials at the least cost of testing and certification, education and training future construction engineers, increased involvement of underrepresented groups in research, education and professional engineering practice, the economic and societal impacts on the national infrastructure.
