The various methods of building a continuously reinforced pavement differ essentially as to ) whether loose bar reinforcing or welded wire fabric is used; and in the degree of mechanization excised. It is a better practice to place the concrete is one lift rather than two lifts with the reinforcing placed between the two lifts. One lift placement has several advantages: (1) it eliminates the need for two mixers, or it eliminates the delay in walking one mixer back to place the second lift, thus increasing the rate of production; (2) it eliminates the use of one strike-off machine, and operator; (3) in case of break-down or other unavoidable delays it eliminates any separation due to hardening of the concrete in the first left before the second lift can be placed; (4) it gives greater assurance that the steel will be maintained in its specified positions in the slab; and (5) it gives greater opportunity for inspection of all ties and laps before the steel is covered. In a typical manual procedure of placing loose deformed bars, the steel is unloaded on the shoulders at pre-planned intervals. The transverse bars with high chairs attached are positioned on the finished subbase. The longitudinal steel is next placed in approximate position on the chaired transverse bars and is located accurately with notched templates before tying in position. The concrete is then placed in one lift through the reinforcement, spread and finished with conventional equipment. Vibration is absolutely essential with this method of installation. Deformed bar mats and welded wire fabric sheets also have been installed in one-lift construction in a similar manner. The placement of reinforcement has been mechanized on some jobs. On one job, deformed bars were delivered in bundles and distributed at intervals along the shoulders. They were then loaded as needed by mobile crane on to a trailer which had a rear platform on which the work crew assembled and tied the steel.
