The purpose of this document is to provide clear and concise information on the C-LTPP Experiment and corresponding database. More specifically, this User's Guide will: describe the C-LTPP Project and corresponding database in sufficient detail so that the user can determine which aspects of the database can fulfill his/her requirements, and provide the user with a simple procedure for formulating a data request. The Canadian Long-Term Pavement Performance (C-LTPP) project involves the systematic observation of in-service highway test sites distributed across Canada. The type of pavements under study are asphalt concrete (AC) overlays constructed over an existing AC pavement with a granular base course. The C-LTPP experiment was strategically designed to allow a comparison of the performance of different overlay rehabilitation strategies under identical traffic, climate, and soil conditions. The Canadian Strategic Highway Research Program (C-SHRP) initiated the C-LTPP project with the design and construction of test sites in 1989 or 1990. At that time, comprehensive field and laboratory testing was conducted on the materials from each layer of the pavement structure. Since then, monitoring data have been collected at each test site (including FWD, Benkelman Beam, surface distress, profile and ruts, skid resistance, traffic, and climatic data), and are expected to continue until the year 2004. All of the experimental data is housed in the C-LTPP Database at the Transportation Association of Canada headquarters in Ottawa. (A)
