Selection of Proof Roller Weights and Tire Pressure. For granular soils, and soil, rock and granular mixtures, use a 50ton (46 metric ton) roller with 150 psi (1030 kPa) tire pressure. The goal of proof rolling is to maximize the load to locate soft subgrade. These soft .
tal pressure and that due to the backfill alone was considered to be the pressure caused by the applied surface load. The backfill material was a pit run gra velly sand consisting of about 40 percent gravel, 48 percent sand, 8 percent silt and 4 percent of 5 micron clay. The liquid lim it was 17 and the plasticity index, 4. It was

Preconsolidation pressure is the maximum effective vertical overburden stress that a particular soil sample has sustained in the past. ... The consolidation curve for a saturated clay showing the procedure for finding the preconsolidation pressure.
Abstract. This is due to the higher equivalent apparent pressure associated with the Proctor test, which is estimated to have a value of kg/cm~. The most severe treatment in the field was due to the 15 passes, and produced equivalent pressures in the range .
Clay minerals can form inplace by weathering ofrocks, or they can be transported and deposited by water or wind. A change in the moisture content ofa soil can cause clay minerals to swell like a sponge or to lose cohesion and collapse.
