Federal Aviation Administration Airport Pavement Instrumentation Project General Information
The pavement structure consists of 17" of PCC concrete, on top of 8" of econocrete base, over 12" of lime-stabilized subgrade, resting on the natural subgrade. Laboratory Tests and Field Tests were conducted on the materials used.
