The report describes the construction and tests made on materials for the test slabs built in the period of time extending from 5 June to 10 July 1944. The design and construction of the original track are given in detail by the Design and Construction Report of June 1944. This reconstruction was started after five of the slabs in Lane 1 had been completely destroyed by the traffic tests, and five of the slabs in Lane 2 had been damaged sufficiently to require the overlay type of construction originally planned in the event of early failure by the traffic tests. The investigation of rigid pavement design was conducted at the Lockbourne Army Air Base, located approximately 15 miles south of Columbus, Ohio, and consists of testing two traffic lanes each, made up of twenty 20 x 40-foot concrete slabs, connected with 10-foot transition slabs. The test slabs form a continuous track with two 490-foot tangents connected by semi-circular turns at each end. The concrete pavement thickness and the base course construction vary from section to section. The Test Track was subjected to traffic applied with heavy earth moving equipment which can be loaded to produce predetermined wheel loads.
