Trr No. 1260 Pavement Design, Management And Performance.pp. 226-245 This paper presents partial results of a 3-year study on the effect of overweight vehicles on FM roads, sponsored by Texas SDHPT.
Results show that the k parameters in the constitutive equations can be calculated using material and physical properties of the soil, and the values of k parameters vary within wide ranges for cohesive and granular subgrade soils.
