The problem of soil compaction by rollers is complex due to influences of a great number of variables of the soil-machine system. Instead of trying to determine the influence of each variable separately, author analyzes the problem using a stochastic model, based on measurements of the maximum vertical stress and density exerted in the soil at different depths and for varying numbers of passes of the roller. The necessary number of passes is determined such that the greatest compaction of the soil at a certain depth is achieved with a probability of 95 percent at a level of significance equal to 0.05. The expected density values agreed with densities found by the Proctor method. Application of the method is illustrated by an example where the soil consists of uniform sand with an unusually high angle of internal friction. Paper is recommended for scientists and soil engineers interested in the application of probability theory. /Author/
