Title: KANSAS EXPERIENCE WITH SMOOTHNESS SPECIFICATIONS FOR CONCRETE PAVEMENTS
Accession Number: 00667672
Record Type: Component
Availability: Find a library where document is available Abstract: Because it affects road users directly, smoothness, or riding comfort, determines the quality of newly constructed pavements. There is a growing interest in the industry in attaining increasingly smoother pavement surfaces. Smoothness specifications for portland cement concrete pavements (PCCP) now in effect in Kansas have evolved through applications over the last 8 years. Pavement profiles of short wavelengths and smaller amplitudes than the industry-accepted 5.1 mm (0.2 in.) can decrease the ride quality of pavements. This experience has led the Kansas Department of Transportation (KDOT) to eliminate the blanking band width in the profilograph trace reduction process. The implementation of this zero or null blanking band was successful and has resulted in better-quality pavements. The latest proposed specifications will increase the amount of bonus that can be achieved but might result in more grinding unless the PCCP pavers were able to improve the pavement smoothness in the middle (full-pay/grind) ranges. An analysis of effect of as-constructed smoothness on the roughness history of pavements has shown that the ride quality over the service life of pavements is highly dependent on the smoothness achieved during construction. Limited cost analysis has shown an increasing amount of bonus achieved in PCCP construction over the last few years, indicating quality paving.
