| 摘要： | Surface smoothness on newly constructed pavement is a major concern of the highway industry. This smoothness, or riding comfort, is an indication of the quality of the newly constructed pavements since it affects road users directly. Smoothness specifications for asphalt concrete (AC) pavements now in effect in Kansas have evolved over the past few years through a number of revisions. Pavement profiles with short wavelengths and smaller amplitudes than the industry-accepted 5.1 mm (0.2 in.) can harm the ride quality of pavements. This experience has led the Kansas Department of Transportation to eliminate the 5.1 mm blanking band width in the profilograph trace reduction process. The implementation of this zero, or null, blanking band was successful and has resulted in smoother asphalt pavements in Kansas. The currently used specifications for AC pavements have been based on the consideration of a number of factors related to the construction of and the measurement of smoothness on AC pavement. The incentive payment amounts have been calculated to make these compatible with the incentive payments for concrete pavement. The results show that these smoothness specifications can be achieved by contractors, and the number of sections in the bonus range indicates that the incentive payments encouraged better-quality paving. These results should have a positive impact on AC paving in Kansas. Overall, an increasing number of miles of pavements with lower profile index values are being constructed since the implementation of smoothness specifications for AC pavements. |
