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

0929619 YouTitle：美国-马来西亚规划访问：路面用立方体石材微观力学的合作研究。该奖项支持美国研究人员、研究生和本科生参加将在马来西亚进行的规划访问。 此次访问将使密歇根理工大学土木工程系的游占平教授与槟城马来西亚大学土木工程学院的Meor Othman Hamzah教授会面。 他们提出的项目将涉及：1）增加密歇根州和马来西亚研究人员在其领先机构的多学科合作; 2）通过合作努力，使用基于先进微观力学的离散元模型，发现车辙和疲劳破坏的机制。 团队将访问USM？的沥青实验室与马来西亚的教授和学生合作，研究和评估在路面中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测试样品与/不与碎石材料的动态模量和弹性模量测试。 美国学生将收到测试结果，以便将数据用于离散元建模。 离散元模型将进一步完善，以研究路面材料的各种材料相（骨料和沥青胶/沥青），以确定沥青路面的车辙和疲劳性能。这两所大学的研究人员之间有足够的利益重叠，表明研究人员可以成功地开展拟议的活动，这种互动将使双方受益。 这种合作将促进对岩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。 预计此次访问的学生将通过为他们提供全球研究经验，为他们提供独特的培训和教育机会。 来自每个国家的科学家和学生之间的这些早期合作可能会带来长期合作，使两个机构都受益。

0929619YouTitle: U.S.-Malaysia Planning Visit: Collaborative Research on the Micromechanics of Cubic Stone Materials for Pavements.This award supports the participation of an American researcher, graduate student and undergraduate students in the planning visit which will take place in Malaysia. 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.
