Performance of Base/Subbase Materials under Frost Action
Several Federal Aviation Administration (FAA) specifications for base and subbase materials were evaluated with respect to frost heave and thaw weakening. The study included both unstabilized and stabilized materials. Most of the unstabilized materials allowed up to 15% fines passing the no. 200 sieve, with the exception of the crushed aggregate base, which allowed no more than 8% fines, and the sand-clay base, which allowed up to 25% fines. The Corps of Engineers (COE) frost-susceptibility criterion was used to delineate the frost susceptibility, while the time to drain a base or subbase layer was used to determine the thaw-weakening potential. The subbase (P-154) and the crushed aggregate base (P-209) met the COE frost-susceptibility criterion, but none of the materials met the COE drainage requirements. However, if the fines contents of the base or subbase were reduced to less then 3%, they did meet the criterion. The resilient modulus of cement-treated soils remained at the level found before freezing, when the cement content was greater than 5%.
