Abstract:

Two mat overlay test sections were constructed and subjected to simulated aircraft traffic. Both test sections consisted of a compacted soil and AM2 mat overlay on rough deteriorated M6 mat. In the first test section, four types of soil cushions were evaluated a thin sand layer, a 4-in.-thick sand layer, a 4-in.-thick clay gravel layer, and a 4-in.-thick, membrane-covered lean clay layer. The test section was subjected to simulated F-4C traffic. Best performance was obtained with the lean clay cushion. he second test section had a 4-in.-thick lean clay soil cushion surfaced with new AM2 over deteriorated M6. The test section had a 2-12 percent crown, and eight different placement configurations were used to determine the optimum pattern for placing 2- by 12- ft mat on a crowned subgrade. The test section was subjected to simulated F-4C and C-130 test traffic.
