Lifecycle Cost Analysis Maintaining Concrete Bridge Decks in Pennsylvania

by QES | Mar 21, 2017 | Pavement Distress and Life-Cycle, Research

This study examines tens of thousands of bridge decks in order to identify their standard deterioration rate. This in turn helps create standardized bridge lifetime expectations and allows researchers to identify more effective maintenance treatments for bridge decks....

Combined Effect Of Tire Contact Pressure And Longitudinal Grade On The Interface Shear Stress Of HMA Overlay Over Ballast Concrete

by QES | Sep 25, 2014 | Pavement Distress and Life-Cycle, Research

Slippage is a common pavement distress resulting from pavement layers separating due to the pressures vehicles put on pavement. No national standard addresses this issue, so this study examines its causes and effects more closely and presents solutions for it....

Prediction Of Surface Texture Of Joints And Cracks Based On Concrete Mixture Properties

by nacb-adm | Sep 21, 2014 | Pavement Distress and Life-Cycle, Research

Load Transfer Efficiency (LTE), or how effectively concrete pavement performs near the edges of each slab, is one of the most important factors in how long that pavement will last. This study presents an empirical model to explain how to optimize the concrete mixture...

Combined Effect Of 3-D Tire-Pavement Contact Load And Thermal Gradients On The Cracking Performance Of Heavy Duty Asphalt Pavements

by nacb-adm | Sep 21, 2013 | Pavement Distress and Life-Cycle, Research

Author(s): Dennis Morian, P.E.; Doug Frith, P.E.; Guangming Wang, Ph.D, P.E. Date published: 2013 Published by: Transportation Research Board Abstract: Top-down cracking (TDC) has been well recognized as a major distress for the heavy duty asphalt pavements yet the...
