Abstract
The report describes a method for rapidly determining the soil strength at forward-area airfields. Soil strength indications are determined by measuring rut depths created by traffic of standard military ground vehicles. Initially, an office study was conducted that established the potential of such a method. Then limited field verification tests were conducted with four standard military ground vehicles operated on a prepared unsurfaced heavy clay subgrade. First-pass rut depths were measured for each vehicle operated empty and with maximum cross-country loading. The results of this testing indicated the feasibility of predicting soil strength based on one-pass rut depth caused by military ground vehicles.Keywords
