Abstract: The objective of this study was to evaluate the effect of an innovative UV light-activated self-healing polyurethane prepolymer (SPP) on the rheological, mechanical, and self-healing properties of asphalt mixture. This new ...

Abstract: This paper presents the results of a comprehensive laboratory testing program that was conducted to develop a performance-based approach to design asphalt-treated base-course mixtures. Eight asphalt-treated base-course ...

Abstract: Field and laboratory testing programs were conducted to develop an efficient methodology for estimating resilient modulus

Abstract: As the price of liquid asphalt continuously climbs, methods are being sought to decrease material costs without compromising material or pavement performance while having a positive influence on sustainability. One potential ...

Abstract: AASHTO's practice for designing flexible pavements requires resilient modulus of the subgrade soils. The resilient characteristics are assumed to account for the permanent deformations of soils. However, this approach can ...

Abstract: Asphalt has been used as a construction material from the earliest days of civilization, but though it has long been used as a waterproofing material in shipbuilding and hydraulics, its use in roadway construction is much ...

Abstract: Asphalt mixtures exhibit both temperature and rate dependencies. Most current constitutive models used in design and prediction of the performance of asphalt pavements do not incorporate both characteristics into their ...
