LOCKBOURNE NO. 3, OVERLAY MAT, PAVEMENT OVERLAY INVESTIGATION.
Abstract:
The purpose and objectives of this investigation were to obtain information on the behavior, under B-29 airplane wheel loads, of flexible overlays of various thicknesses and design on a rigid pavement with a relatively poor subgrade, and to correlate this information with that obtained by the South Atlantic Division for such overlays on rigid pavements with good and medium subgrades. This report is concerned with the design and construction of the Test Section and is prepared for the purpose of providing a record of the design features, the details of construction, and the physical properties of the concrete, overlay materials, and subgrade soil. The report will serve as a guide in analyzing the results obtained by the traffic tests and accompanying measurements of strain and deflection. Author
