Description: Technical Report
Summary: This report presents a summary tabulation of the pertinent data on pavements, base courses, and subgrades and on traffic histories from twenty-five Air Force bases where the pavement design is effected by frost conditions. The gross plane load evaluations of the pavements during both the normal period, where there is no weakening due to frost melting, and during the frost melting period have been determined using criteria presented in Chapters 2, 3 and 4, Part XII of the Engineering Manual. Results of pavement condition surveys made at fifteen of the airfields are tabulated and correlated with the pavement evaluations and traffic histories. All of the fields included in the tabulation have been subjected to a relatively large number of operations by planes of weights exceeding both the "normal" and "frost condition" evaluations which has generally resulted in pavement failures or distress at the portions of the fields receiving the most traffic usage. Rigid pavements generally have given satisfactory performance where the slab thickness was at least 70 per cent of the "frost condition" design thickness required to support the heaviest type of planes using the field an average of five or more operations daily. A limited amount of flexible pavement service behavior data is presently available from four of the airfields.
