Abstract: This paper is a continuation of an earlier overview on the subject and presents the results of a sensitivity analysis that assessed the ability of the new design guide to portray the impact of temperature and moisture ...

Abstract: The mechanistic–empirical (ME) design guide developed under the National Cooperative Highway Research Program represents a true change in the approach to engineering road structures. Changes in material properties with ...

Abstract: Horizontal reverse curves are used in all types of highways either in mainline alignments or in freeway interchange ramps. At present, minimum radius requirements for reverse curves are determined based on vehicle performance ...

Abstract: According to current highway design standards, horizontal and vertical alignments are treated separately in two-dimensional (2D) projections. In this paper, a model developed by the writers is used to study the effects of ...

Abstract: Thermal cracking of asphalt pavements is a serious problem in Canada and the northern parts of the United States. On many occasions, either at the design stage or during service, highway agencies demand a forecast of ...

Abstract: Every year, large amounts of pavement deicing chemicals are used for snow and ice control on Canadian highways and airports. Until recently, urea had been the only pavement deicing chemical in use at Canadian airports, but ...

Abstract: Compaction of the asphalt mix is that part of the construction process largely responsible for the structural properties and performance of the pavement. By increasing density and reducing air voids, compaction adds strength ...

Abstract: The effect of warm-mix additive (WMA) on styrene-butadiene-styrene (SBS)-based high-viscosity asphalt (HVA) was conducted in this study. First, the physical properties for control HVA and HVA with WMA (RH, EC-120, and ...
