TRAFFIC TESTS ON PORTAGE LAKE ICE.

Abstract

A limited series of traffic tests were conducted on floating lake ice using a dual-wheel loaded to gross weights of 20,250; 28,250 and 36,250 lbs. Deflections were measured under static and moving loads on a continuous ice sheet and adjacent to a free edge. Representative samples of the ice were tested in unconfined compression, direct shear, flexure, and under a dynamic load (steady-state vibration). Crystal size and orientation were measured. An analysis of test results is presented using linear elastic theory and a method is proposed for estimating time variations of deflection. (Author)
