Using high-speed texture measurements to improve the uniformity of hot-mix asphalt
(Virginia Center for Transportation Innovation and Research, 2003-05-01)
This study introduces Virginia's efforts to apply high-speed texture measurement as a tool to improve the uniformity of hot-mix asphalt (HMA) pavements. Three approaches for detecting and quantifying HMA segregation through ...
Optimizing the Lateral Wandering of Automated Vehicles to Improve Roadway Safety and Pavement Life
(SAFE-D: Safety Through Disruption National University Transportation Center, 2019-12)
Because most automated vehicles (AVs) are programmed to follow a set path and maintain a lateral position in thecenter of the lane, over time significant pavement rutting will occur. This study directly measured AV ...
Latest Development in the Processing of Pavement Macrotexture Measurements of High Speed Laser Devices
Pavement macrotexture is an important property that affects tire-pavement interactions like friction, tire pavement noise, splash and spray, and rolling resistance. Macrotexture measurement is generally divided into two ...
Multivariate Volumetric Specifications and Dynamic Modulus as a Quality Measure for Asphalt Concrete Materials
(Virginia Center for Transportation Innovation and Research, 2010-06-01)
The Virginia Department of Transportation (VDOT) has worked toward end-result specifications (ERSs) in asphalt concrete since the mid-1960s. As stated by Hughes et al. (2007), true ERSs can lead to a reduction in VDOT's ...
Laboratory Tests for Hot-Mix Asphalt Characterization in Virginia
(Virginia Center for Transportation Innovation and Research, 2005-06-01)
This project reviewed existing laboratory methods for accurately describing the constitutive behavior of the mixes used in the Commonwealth of Virginia. Indirect tensile (IDT) strength, resilient modulus, static creep in ...
Determination of the In-Place Hot-Mix Asphalt Layer Modulus for Rehabilitation Projects Using a Mechanistic-Empirical Procedure
(Virginia Center for Transportation Innovation and Research, 2006-07-01)
This project evaluated the procedures proposed by the Mechanistic-Empirical Pavement Design Guide (MEPDG) to characterize existing hot-mix asphalt (HMA) layers for rehabilitation purposes. Thirty-three cores were extracted ...
Field Investigation of High Performance Pavements in Virginia
(Virginia Center for Transportation Innovation and Research, 2005-01-01)
This study evaluated 18 pavement sections located in high-traffic highways in Virginia to find a premium pavement design with a life span of 40 years or more using current and past field experience. The selected pavement ...
Evaluation of the Cargill Safelane Surface Overlay
(Virginia Center for Transportation Innovation and Research, 2009-02-01)
A recent development in polymer concrete overlays is the Cargill SafeLane surface overlay (SafeLane overlay). The 3/8-in-thick overlay is constructed with epoxy and broadcast aggregates, as are typical multiple-layer epoxy ...
US Army Experience with Precast Panels for Military Airfield Pavement Repairs
The evaluation of expedient Portland cement concrete (PCC) repair technologies has been the focus of the pavements research community for decades due to ever decreasing construction timelines. Precast concrete panel ...
