Abstract:

The primary purpose of this research effort was to assess the presently specified smoothness criteria for new construction of asphaltic concrete surfaces using various rolling straightedges and roadmeters. This assessment was to be based on the correlation between the various systems of smoothness (or roughness) measuring devices and the precision of each of the devices. Furthermore, if the findings indicated that a revision in smoothness criteria is necessary, then an attempt would be made to formulate such smoothness criteria in relation to the rideability of the pavement surface as assessed by the roadmeters.

While the primary aim reflected evaluation of new construction only, measurements were also included on older pavement surfaces. This was considered desirable for definition of surfaces that should be considered unacceptable. The current specifications for surface smoothness define any segment exceeding 2.5 percent of total length, at 1/8 inch (3.175 mm) tolerance, as unacceptable and subject to 50 percent penalty.
