TL;DR: In this article, the performance of hot-mix asphalt (HMA) with high amounts of RAP and to identify any special considerations that must be met to utilize these higher RAP contents.

TL;DR: In this paper, the detection of multiple-layer reflections within the ground penetrating radar (GPR) return is solved by iteratively detecting the strong reflections present within the GPR signal using either a threshold or a matched filter detector.

TL;DR: In this article, the authors measured horizontal transverse and longitudinal strains induced in the hot-mix asphalt (HMA) during compaction with a steel drum compactor both with and without vibrations, and used the data collected and used to determine the vertical compressive stress pulse induced by a moving truck at different locations beneath the pavement surface.

TL;DR: In this article, a 3D finite element (FE) model was developed to investigate the dynamic responses of thin, flexible pavement under impulsive loading similar to a falling weight deflectometer test.

TL;DR: In this article, the authors evaluated the feasibility of using friction indicators as tools for improving winter maintenance operations and mobility and found that the use of friction measurements for this purpose is feasible (especially when deceleration devices are used), but devices with an extra wheel may not represent a practical solution to friction measurement.
