Available in PDF, EPUB and Kindle. Book excerpt: Pavement smoothness is a major factor affecting the performance of the highway surface and the safety and satisfaction of the traveling public. Smooth pavement results in better gas mileage, less vehicle wear, and less driver stress and fatigue. Pavement smoothness is the single most important indicator of pavement condition as viewed by the traveling public. Many state highway agencies, including the Kansas Department of Transportation (KDOT), have adopted specifications that set forth a goal of minimal levels of roughness for newly built pavements. Some specifications also include significant incentive/disincentive provisions to encourage contractors to concentrate their efforts on building smooth pavements. This report highlights the development of the smoothness specification for Portland Cement Concrete Pavement (PCCP) beginning in 1985 and for Asphalt Concrete Pavement (ACP) beginning in 1990. The early specifications used the 0.2 inch Blanking Band while evaluating the traces generated using the manual California type profilograph. In 1986, incentive/disincentive clauses allowed bonus payment for PCCP constructed with less than 4 in/mile of surface roughness and penalty (reduced payment) for over 12 in/mile using the 0.2 inch Blanking Band. The implementation of the smoothness specification resulted in dramatic improvement in PCCP smoothness. In 1990 the stage was set for change. The initial projects requiring the use of the profilograph with the 0.2 inch Blanking Band to measure smoothness of ACP provided a high percentage (64%) of bonus level sections thus indicating the need for a modification to the existing specification. Similarly, the PCCP projects built in 1990 also had a high percentage (63%) of bonus level sections while using the 0.2 inch Blanking Band. However, there was one PCCP reconstruction project that had achieved about 47% bonus sections but produced a high frequency vibration in the vehicle when driving at normal speed. A review of the original profilograph traces revealed a short length sine wave roughness that was slightly less than 0.2 inches in amplitude and thus was almost completely covered by the 0.2 inch Blanking Band.

This book was released on 1990 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to construction engineers, pavement designers, contractors, and others interested in construction of new highway pavements with smooth surfaces. Information is provided on the various devices and specifications that are being used to obtain smooth pavements. The public rates a pavement primarily on its smooth-riding characteristics and highway agencies recognize that constructing smooth pavements results in fewer problems later and lower annual maintenance costs. This report of the Transportation Research Board describes the devices and specifications highway agencies use to ensure that newly constructed pavements will provide a smooth ride.

Book excerpt: Nearly all State highway agencies use smoothness specifications to ensure that hot-mix asphalt (HMA) and portland cement concrete (PCC) pavements are built to high levels of smoothness. About half of all current State smoothness specifications for HMA and more then three-fourths of all current PCC smoothness specifications are centered around the Profile Index (PI), as often measured using a profilograph. The vast majority of these specifications utilize a 5-mm (0.2-in.) blanking band in computing PI (i.e., PI5-mm). Assistance in selecting appropriate IRI and PI0.0 specification limits is needed to provide a basis for modifying current specifications to these more reproducible and portable smoothness indices. This research effort has developed a series of relationships between IRI and PI that can assist States in transitioning to IRI or PI0.0 smoothness specification for HMA and PCC pavements.

Book excerpt: In this study, roughness of 17 pavement sections, built between 1998 and 2001 were analyzed. These sections were constructed over different subgrade and base types, and different asphalt binder aggregates were used. Annual roughness data was collected from the Pavement Management Information System database of the Kansas Department of Transportation. In addition, five new sections, built over the last three years, were also monitored. Roughness data on these sections were collected periodically. International Roughness Index (IRI) was used as the roughness statistic for analyzing both types of sections.
