“…AC Rutting is permanent deformation that occurs due to traffic loads in the AC pavement layer of a roadway (Witczak, Von Quintus, & Schwartz, Downloaded by [University of Nebraska, Lincoln] at 12:14 14 June 2016 1997). Rutting in the AC layer is caused by three main factors: poor materials, bad quality control during construction, and inadequate design (Fang, Haddock, White, & Hand, 2004).…”

An industry-wide emphasis on sustainable asphalt practices has given rise to increasing use of warm-mix asphalt (WMA) technologies. WMA reduces both binder viscosity and mixing and compaction temperatures by 20-55°C during the asphalt mix production and laydown process. This research investigates several bio-derived WMA additives that act as chemical modifiers with surfactant properties. Two established additives derived from the forest products industry are studied as well as a WMA additive in development that is derived from corn. The objective of this research is to use the new AASHTOWare Pavement ME Design to compare the established forest product WMA additives with the new WMA corn-derived additive that is in development. Using binder and mix test results as input values in AASHTOWare Pavement ME Design, predicted pavement performance was evaluated for sensitivity to different climatic conditions seen in the Midwestern United States. Results indicate that the climatic conditions have a larger impact on the pavement performance as compared to the impact from binder type and additive choice. The corn-derived WMA additive was similar to the other established WMA additives and HMA control group showing similar pavement performance predicted by the AASHTOWare Pavement ME Design.

Abstract. This paper presents a numerical study of an aircraft wheel impacting on a flexible pavement. The proposed three dimensional model simulates the behaviour of flexible runway pavement during the landing phase. This model was implemented in a finite element code in order to investigate the impact of repeated cycles of loads on pavement permanent deformation.In the model a traditional multi-layer pavement structure was considered. In addition, the asphalt layer (HMA) was assumed to follow an elasto-viscoplastic behaviour.The results demonstrate the capability of the model in predicting the permanent deformation distribution in the asphalt layer.

“…With the development of computing technique and the publishing of a variety of commercial finite element software, modeling permanent deformation using experimentation-based viscoelastic mechanics has been preferred by many researchers [7][8][9]. However, their studies focused mainly on rutting in simple road, i.e., straightaways.…”

Abstract:This study aims to evaluate the permanent deformation of high-modulus asphalt pavement in special road using viscoelastic theory. Based on the creep test, the Prony series representation of Burgers model parameters for different asphalt mixtures were obtained and used in the deformation simulation of a high-modulus asphalt pavement situated in a horizontally curved ramp. The orthogonal design method was used to show the effect of different factors on the deformation. Results reveal that rutting in curved ramp was greater than in straightaway. Further, evident upheaval was found on the downhill pavement surface and outer pavement parts of the curve due to longitudinal friction force and sideway force. In addition, the upper and middle asphalt courses in such road seemed more crucial to pavement anti-rutting performance, since inclusion of shear force changed pavement deformation characteristic and the potential rutting area tended to move up. Finally, a preliminary equation to predict rutting in sloped and curved road with widely accepted pavement structure in China was proposed.
