Description: Technical Report
Summary: This report presents the results of an investigation relative to the prediction of the depth of frost penetration in multilayer soil profiles. An adaptation of the Modified Berggren formula is presented and computed results are compared with "exact" solutions for the depth of freezing as determined by the hydraulic analog computer developed under the contract. Nine cases were investigated, representing typical soil profiles below bituminous concrete airfield pavements. In seven cases, the pavement surface temperature was assumed to drop suddenly to a given value below freezing where it remained constant. In the remaining two cases, the surface temperature was assumed to vary sinusoidally over an annual period. Results of these tests indicate that the proposed adaptation of the Modified Berggren formula underpredicts the frost depth by approximately 3 percent, However, this error is believed to be insignificant compared to those errors in the predicted depth of frost penetration in any practical case arising from uncertainties in the thermal properties of the soil, particularly the thermal conductivity, and from unknown pavement surface temperatures. These factors present the most fruitful areas for future research on the depth of frost penetration prediction.
