Papers are invited for an International Symposium on Mechanical Properties of Frozen Soils to be held January 31, 2013. Sponsored by ASTM Committee D18 on Soil and Rock, the symposium will be held at the Hyatt Jacksonville in Jacksonville, Florida in conjunction with the January standards development meetings of Committee. Objective The symposium will provide a forum for exchange of ideas on current research on the testing of mechanical properties of frozen ground. A key objective is to identify new opportunities for standards and specifications that will facilitate construction on frozen soils as well as utilization of natural resources in frozen soil conditions. Articles on triaxial testing, dynamic testing and tensile strength testing of frozen soil and tailings are of interest. Papers on other frozen soil testing methods are also welcome. Providing a rationale for the various details within a new standard for triaxial testing of frozen soils is of particular interest.
