Frost Heave Study

Abstract

During 1986, reports were received that some cadastral survey monuments were being pushed from the found in cold climates by frost heave action. Early reports stated that the rod-type monuments were given the most trouble. Meetings were held at various cadastral survey offices to discuss the frost heave problem and to determine a course of action to study the problem in more depth. By thoroughly investigating this problem and with proper evaluation, it was hoped that procedure could be developed that may reduce or even prevent some of this frost heaving. It was concluded that two frost heave sites would be carefully selected and established to study and evaluate how frost heave action affects: 1. Various monument designs 2. Various materials 3. Various installation practices 4. Varying depths monuments are set 5. Use of finned aluminum rods This is the ninth report covering the ninth visit to both sites during March 2021.
