U.S.-Malaysia Planning Visit: Collaborative Research on the Micromechanics of Cubic Stone Materials for Pavements

题目：美国-马来西亚计划访问：路面用立方石料微观力学合作研究。该奖项支持一名美国研究人员、研究生和本科生参加将在马来西亚进行的计划访问。此次访问将使密歇根理工大学土木工程系的游展平教授与槟城马来西亚理科大学土木工程学院的Meor Othman Hamzah教授会面。他们提出的项目将包括：1)加强密歇根和马来西亚两国主要机构的研究人员之间的多学科合作；2)通过合作，利用基于先进细观力学的离散元模型，发现车辙和疲劳损伤的机理。考察团将参观USM？s沥青实验室与马来西亚的教授和学生合作，研究和评估在路面上使用立方体集料以减少车辙可能性的可行性。学生也将有机会参与有/没有立方石材料的样品的动态模量和弹性模量测试。美国学生将收到测试结果，以便使用这些数据进行离散元素建模。为了确定沥青路面的车辙和疲劳性能，离散元模型将进一步细化，以研究路面材料的不同材料阶段（集料和沥青/沥青）。两所大学的研究人员之间有足够的兴趣重叠，表明研究人员可以成功地开展所提议的活动，并且这种互动将使双方受益。这项合作将促进对立方石材料微观力学的发现和理解，同时通过为学生计划的具体活动促进教学、培训和学习。预计此次访问将为学生提供独特的培训和教育机会，为他们提供全球研究经验。来自两国的科学家和学生之间的这些早期合作可能会导致长期合作，这将使两个机构都受益。

The visit will enable Professor Zhanping You in the Civil Engineering Department at Michigan Technology University to meet with Professor Meor Othman Hamzah in the School of Civil Engineering at the University Sains Malaysia (USM) in Penang. Their proposed project will involve: 1) increasing multidisciplinary collaboration among researchers in Michigan and Malaysia at their leading institutions; and 2) discovering the mechanism of rutting and fatigue distresses by using advanced micromechanics based discrete element models through the collaborative effort. The team will visit USM?s Asphalt Laboratory to work with the Malaysian professors and students to study and evaluate the feasibility of using cubical aggregated in pavement to reduce rutting potential. The students will also have an opportunity to participate in the testing of samples with/without cubic-stone materials on dynamic modulus and resilient modulus testing. The U.S. students will receive the testing results in order to use the data for discrete element modeling. The discrete element model will be further refined to study the various material phases (aggregates and mastic/asphalt) of pavement materials in order to determine the rutting and fatigue performance of asphalt pavements. There is sufficient overlap of interests between researchers at the two universities to indicate that the researchers can successfully pursue the activities proposed, and the interaction will benefit both sides. This collaboration will advance discovery and understanding of cubic-stone materials micromechanics, while promoting teaching, training, and learning through the specific activities planned for the students. It is anticipated that the inclusion of the students in this visit will provide them unique training and educational opportunities by providing them a global research experience. These early collaborations between the scientists and students from each country will likely lead to long-term collaborations that will benefit both institutions.
