PERFORMANCE OF A CONTINUOUSLY REINFORCED CONCRETE OVERLAY IN CONNECTICUT, REPORT I, CONSTRUCTION

A three-lane (in both directions) continuously reinforced concrete overlay has been placed over an old two-lane concrete pavement built in accordance with both the 40-ft contraction-joint and 100 ft expansion joint design. The pavement is unique in that of the 3 lanes, 1 1/2 are placed on a gravel base, while the other 1 1/2 lanes are over old concrete, resulting in nonalignment of longitudinal joints. Depth of pavement was increased from 6-inches to 8-inches in the outside lane, which falls entirely on the gravel. During the course of paving, leave-out sections were requried to accommodate traffic. Special procedures to cool the pavement ends and reduce end movement were followed prior to and after placement of these sections. Data on initial crack frequencies are also presented. /Author/
