Abstract: A review of several relationships commonly used by pavement engineers for structural characterization of subgrade soils, subbase, and base is presented. A careful examination of the literature on the subject revealed that ...

Abstract: This paper presents the results of an experimental investigation on the interface bond strength between reinforcing fibers embedded in a calcium sulfoaluminate (CSA) cement matrix, utilizing the single-fiber pullout test. ...

Abstract: The study examined several formulations that may serve as a green substitute for traditional portland cement. The primary objective of the project was to produce a durable, low-energy cementitious material from flue gas ...

Abstract: Some states have recommended changing the definition of flat and elongated aggregates from 5:1 to 3:1 and an increase in the maximum allowable percentage of flat and elongated (F&E) particles to 20% or higher in the Superpave ...

Abstract: At the same time that state departments of transportation are allowing contractor-performed quality control, they are also concerned about using the contractor-reported data for acceptance and payment purposes. The question ...

Abstract: Field data from a section of heavily instrumented concrete pavement on the Gene Snyder Freeway (I-265), Louisville, Kentucky were closely examined. To predict the mechanical behavior of the rigid pavement, a three-dimensional ...

Abstract: This paper deals with accuracy issues related to using ground penetrating radar (GPR) for determining the surface layer thickness of asphalt and concrete pavements. Additionally, tests were conducted to identify GPR’s ...

Abstract: The study presented in this paper analyzed the development patterns of fatigue cracking shown in flexible pavement test sections of the long-term pavement performance (LTPP) program. A large number of LTPP test sections ...

Abstract: In order to identify the improvement needs on transportation facilities and the associated budget, the transportation agencies need to have a reasonable estimate of the facilities’ future condition. Using asphalt concrete ...

Abstract: This research was conducted to study subsurface drainage issues surrounding an asphalt overlay. The type of pavement that was examined in this study was a Superpave overlay on top of a Broken and Seated Jointed Reinforced ...
