Accomplishments and Benefits Database: This document highlights the accomplishments and benefits of the LTPP program over the first 20 years of data collection. During development of this report, an extensive database of existing LTPP reports, products, and research results was compiled. The LTPP Literature Database can be accessed here: http://ltpp.org/user_corner.shtml.
FHWA LTPP Web Site: FHWA maintains an LTPP Web site to disseminate information resulting from the LTPP program. www.fhwa.dot.gov/Pavement/ltpp
LTPP Customer Support Service Center: LTPP data requests, technical questions, and data user feedback can be submitted to the LTPP Customer Support Service Center via email at LTPPinfo@dot.gov or by calling 202-493-3035.
LTPP Products Web Site: Many of the products mentioned in this document can be found online at the LTPP products Web site, which also contains online access to the LTPP database. www.ltpp-products.com
Materials Reference Library: More than 1,000 tons of sample materials are held at this site for research purposes. Included are pavement cores, asphalt cement, portland cement, aggregates, and other materials. www.ncenet.com/ltpp/mrl
Strategic Plan for LTPP Data Analysis: Since 1999, analysis of the LTPP data at the national level has been guided by the Strategic Plan for Data Analysis. The Strategic Plan was developed by the TRB Expert Task Group on LTPP Data Analysis, recommended by the TRB LTPP Committee, and adopted by FHWA as the basis for selecting LTPP analysis projects and evaluating progress in LTPP data analysis. www.fhwa.dot.gov/pavement/ltpp/stratplan/strategic.cfm
ASCE-LTPP International Contest on LTPP Data Analysis: The contest is designed to encourage university students, professors, and highway department engineers from around the world to get involved in using the LTPP database. www.fhwa.dot.gov/pavement/ltpp/contest.cfm
SPS Traffic Data Collection Pooled Fund Study: This study includes two phases. Phase I consists of assessing, evaluating, and calibrating the current weigh-in-motion and vehicle classification systems used to collect traffic data at SPS sites across the country. Phase II consists of installing and maintaining new weigh-in-motion equipment as necessary to ensure high-quality data collection.
