This paper describes a series of 3-point bend tests performed on alluvium-reinforced ice. Only one type of alluvium was used, and beams were broken at 3 temperatures: -5 deg, -10 deg, and -20 deg Cc. Since all beams exhibited a brittle-type failure, a Weibull analysis was performed on the results obtained at each temperature. From the analysis, a micromechanistic description of the failure process is given, and it appears to describe the observed results well. The details of the experimental procedure is described, and the results of the study are interpreted and discussed. It was found that the mean bending strength showed a clear increase as temperature decreased. The Weibull modulus also increased as temperature decreased, apparently reaching a plateau value.
