Abstract: The use of recycled materials in pavement engineering has a great potential to benefit our society in terms of reducing demands on natural pavement materials, reducing environmental problems, and conserving energy. However, ...

Abstract: The deterioration of Portland cement concrete pavement is most often due to intrusion of water into the pavement system as well as due to inferior performance of the transverse joints. The infiltration of surface runoff ...

Abstract: During recent years, the rapid growth of shale gas exploration nationwide has resulted in a large number of overweight truck trips on roadways in areas with shale gas development. The Louisiana Department of Transportation ...

Abstract: In September of 2005, Hurricane Katrina devastated New Orleans and caused sustained flooding. Limited pre- and postflooding tests indicated that the pavement structures tested were adversely impacted by the flood water. ...

Abstract: This paper presents a theoretical investigation on excess sludge production in membrane bioreactors for municipal wastewater treatment. Based on mass balances of sludge and substrate, a formula to predict the excess sludge ...

Abstract: Interaction between steel cables and concrete is complicated in prestressed concrete bridges, especially in curved prestressed concrete bridges. The most significant behavior of curved beam bridges under the loads is that, ...

Abstract: To facilitate the use of recycled materials in pavement construction, a mechanistic-based approach is required to better characterize pavement base materials. This paper demonstrates the application of the shakedown theory ...
