Calibration of Fatigue Transfer Functions for Mechanistic-Empirical Flexible Pavement Design

Priest, Angela (2005-12-15)

As agencies continue to adopt mechanistic-empirical (M-E) pavement design, the need for locally calibrated transfer functions will continue to increase. Transfer functions are the critical link from mechanical pavement ...

Comparison of New Technology for Measuring Ride Quality

Hays, Joshua (2006-12-15)

Ride quality of a pavement is quantified by a statistical index. The statistical index and the profile device used to assess the index are major variables in pavement smoothness. Due to the wide range of these variables ...

Determining the Optimum Compaction Level for Designing Stone Matrix Asphalt Mixtures

Xie, Hongbin (2006-05-15)

As Stone matrix asphalt (SMA) becomes more widely used in the United States, there is a need to further refine its mix design procedure. Some states have found that 100 gyrations with the Superpave Gyratory Compactor (SGC) ...

Development of a Non-solvent Based Test Method for Evaluating Reclaimed Asphalt Pavement Mixes

Carter, Alan (2005-08-15)

The objectives of this research are twofold. The first is to develop and validate an indirect tension stress relaxation test methodology for assessing asphalt binder properties using compacted hot mix asphalt (HMA) samples. ...

Development of Flexible Pavement Rut Prediction Models from the NCAT Test Track Structural Study Sections Data

Selvaraj, Suresh Iimmanuel (2007-08-15)

This research study was attempted to address two of the most important aspects of mechanistic-empirical (M-E) pavement design. As M-E design continues to advance toward full implementation by state agencies, there is a ...

Integration of GIS into Pavement Management Systems for Low Volume County Roads

Grass, David (2007-05-15)

Geographic Information Systems (GIS) have often been used for highway pavement management (PM), but rarely for low volume county roadway systems. Methods for implementing GIS as a useful tool for county engineers in ...

Optimizing Haul Routes Using Geospatial Technologies for the Delivery of Ready-Mix Concrete in Urban Areas

Rao, Pradeep (2007-05-15)

In the ready-mix concrete industry, timely and uninterrupted delivery of ready-mix concrete to a construction site is of utmost importance for efficient construction operation. Due to ever soaring fuel prices and small ...

Predicting Field Performance on the NCAT Pavement Test Track

Powell, Raymond (2006-08-15)

An experimental facility has been constructed near the campus of Auburn University for the purpose of conducting research to extend the life of flexible pavements. Experimental sections on the 2.8 kilometer Pavement Test ...

Transferring Alabama's Smoothness Specifications from PI-based to IRI-based

Huang, Wen (2006-08-15)

Currently, Profilograph Index (PI) is deployed as the pavement smoothness evaluation index in the Alabama DOT’s smoothness specifications. The specifications set the incentive, full and disincentive payment levels to ...
