Book Description
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 Description
"This new ASTM publication presents the latest information on the practical and developmental aspects of pavement surface evaluation procedures and technologies, including their reliability and relevancy. Seven peer-reviewed papers cover: * Pavement surface characteristics measurement procedures and equipment * Approaches to enhance the reliability and accuracy of pavement surface evaluation systems * Approaches to harmonization between different measurement devices for specific pavement surface condition indicators * Assessment of current pavement condition indicators and their relevancy level for use in asset management * Assessment of factors influencing the interaction of tire/pavement surface characteristics * Assessment of automated distress survey systems * Evaluation of new/promising technologies for pavement condition surveys."--Publisher's website.

Book Description
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.
