Abstract: In 1978 reconstruction was begun on the runway of the Lebanon Regional Airport, Lebanon, New Hampshire. The runway had experienced severe differential frost heaving and cracking during the previous three winters, which had resulted in closure of the facility during periods of extreme roughness. At the request of the Federal Aviation Administration and in conjunction with the reconstruction, CRREL undertook to study the newly constructed pavements to investigate the relationships between weakening of the pavements, frost heave of the pavement surfaces and the position of the freezing front. Temperature sensors were placed within the newly constructed pavement sections, and during the winters of 1979, 1980 and 1982 temperature data were recorded, and level surveys and repeated plate bearing tests were performed in order to provide data for the investigation. The three pavement sections were constructed to investigate the effect of section thickness on the level of frost protection provided. The sections consisted of 4 in. of asphalt concrete, 6 in. of crushed gravel and 22, 30 and 38in. of well-graded sand subbase material. The 48-in. section provided the highest level offrost protection to the subgrade. However, all three pavement sections maintained resilient stiffness values during the spring thaw period on the order of two to three times that of the pavement before reconstruction. Also, frost heave in all sections was reduced to levels that would not cause difficulty for aircraft using the facility.
