Use of Long-Term Pavement Performance Data for Calibration of Pavement Design Models

Transportation Research Record: Journal of the Transportation Research Board, 2001
The benefits of long-term pavement performance data for calibration of the AASHTO flexible pavement design model for Ontario conditions are documented. To ensure that the AASHTO-Ontario pavement design model reflects Ontario pavement design practice and matches the observed pavement performance, long-term pavement performance data for 65 flexible ...

Factors Affecting Asphalt Pavement Density and the Effect on Long Term Pavement Performance

2010
The Kentucky Transportation Center, the Asphalt Institute, and the Kentucky Transportation Cabinet worked together in order to identify factors that affect asphalt pavement density, and to then evaluate their effect on long term pavement performance. By determining which variables are most influential to pavement performance (i.e.

Calibration of Performance Models for Jointed Plain Concrete Pavements Using Long-Term Pavement Performance Database

Transportation Research Record: Journal of the Transportation Research Board, 1998
A methodology for calibrating performance models for jointed plain concrete pavements (JPCP) is presented; it is based on statistical analysis of data from the Long-Term Pavement Performance (LTPP) database. The methodology provides calibration factors to pavements in four climatic regions (dry-freeze, dry-nonfreeze, wet-freeze, and wet-nonfreeze) for ...

Early Evaluation of Long-Term Pavement Performance Specific Pavement Studies-2, Colorado

Transportation Research Record: Journal of the Transportation Research Board, 2000
The Long-Term Pavement Performance (LTPP) Program included the construction of rigid pavement sections for evaluation. These test sections, designated Specific Pavement Studies (SPS)-2, were constructed on the basis of an experiment matrix that includes pavement slab thickness [202 mm (8 in.) and 280 mm (11 in.)], base type (permeable asphalt-treated ...

Feasibility of Accelerated Pavement Testing to Evaluate Long-Term Performance of Raised Pavement Markers

Transportation Research Record: Journal of the Transportation Research Board, 2006
Raised pavement markers (RPMs) are used to provide long-range nighttime guidance to drivers. The visibility of these markers lessens over time, and they must be replaced. Thus, many state departments of transportation test various markers to provide the most durable marker available. One of the most critical approaches is the field test whereby markers
