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 ...
Flexible Pavements and Climate Change: A Comprehensive Review and Implications
Flexible pavements and climate are interactive. Pavements are climate sensitive infrastructure, where climate can impact their deterioration rate, subsequent maintenance, and life-cycle costs. Meanwhile, climate mitigation ...
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 ...
Application of Balanced Mix Design Methodology to Optimize Surface Mixes with High-RAP Content
The most common use of reclaimed asphalt pavement (RAP) is in the lower layers of a pavement structure, where it has been proven as a valid substitute for virgin materials. The use of RAP in surface mixes is more limited, ...
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 ...
