Construction Control of Rigid Pavement Roughness.

摘要

Paving procedures were monitored and performance surveyed for 5years on 108portland cement concrete pavement projects to determine the factors affecting as-built surface roughness. The California profilograph was reported earlier in this investigation to be a fast,accurate,and reproducible method of measuring roughness within a few hours after paving. By contrast, conscientious inspection with a 10-ft straight edge and correction of out-of-tolerance bumps during construction do not assure a smooth-riding pavement. Slip-form paving generally produces a much smoother surface than paving with conventional fixed side-forms. Although good results can be achieved by either method,neither assures smoothness.
