CONTINUOUSLY REINFORCED CONCRETE PAVEMENT PERFORMANCE

Two short sections of continuously reinforced concrete pavement were constructed in South Dakota in 1963. After five years of service both sections are performing satisfactorily. Variations in design between the two test sections included depth of steel placement and the method of anchoring the pavement ends. A slight difference in crack spacing and pattern is exhibited in the two sections with the mid-depth steel placement causing fewer cracks than the section with steel placed above mid-depth. The section which allowed unrestrained end movement of the slab is performing more satisfactorily than the section with restraining lugs beneath the slab to restrict end movement.
