National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Characterization of Transverse Profiles.

PB2001105685

Publication Date	2001
Personal Author	Simpson, A. L.
Page Count	306
Abstract	A study of the transverse profile data currently being collected under the Long Term Pavement Performance project was undertaken. The data were collected by three processes: (1) Dipstick (trademark), (2) a photographic method, and (3) straightedge used to collect rut depths. This study examined several indices for the purposes of quantifying and qualifying the transverse profiles. It is recommended that five indices by added to the National Information Management System. These indices include the area of the rut below a straight line connecting the end points of the transverse profile, the total area below the straight lines connecting the maximum surface elevations, the maximum depth for each wheelpath between a 1.8-m straightedge placed across the wheelpath and the surface of the pavement, and the width of the rut based on a 1.8-m straighthedge. These indices were studied in order to determine typical trends by climate, surface thickness, soil type, and age. In addition, the time-series trends for each test section were studied in order to determine whether any anomalies existed and the potential causes of these anomalies.
