RISUse of Infrared Thermography to Detect Thermal Segregation in Asphalt Overlay and Reflective Cracking Potential
Publisher: American Society of Civil Engineers
Abstract: The objectives of this study were to assess whether temperature differentials measured using infrared thermography (IRT) occur in an overlay built on top of discontinuities such as joints and cracks and to study the ...
Effects of Asphalt-Mixture Characteristics and Vehicle Speed on Fuel-Consumption Excess Using Finite-Element Modeling
Publisher: American Society of Civil Engineers
Abstract: The effects of pavement type on fuel consumption have received considerable attention in recent years, yet the influence of asphalt mixes characteristics and vehicle speed on fuel consumption excess has not been evaluated. ...

Modeling of Strain Energy Absorbers for Rehabilitated Cracked Flexible Pavements
Publisher: American Society of Civil Engineers
Abstract: The objective of this paper is to evaluate the potential use of a specially designed geocomposite membrane to delay the reflection of cracks in flexible pavement systems. Two-dimensional finite element models, which simulate ...
Effectiveness of Steel Reinforcing Nettings in Combating Fatigue Cracking in New Flexible Pavement Systems
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the effectiveness of steel paving mesh as reinforcement for hot-mix asphalt (HMA) in new flexible pavement systems. Two sections of the Virginia Smart Road were instrumented and constructed incorporating ...
Laboratory Performance of Asphalt Mixtures Containing Recycled Asphalt Shingles and Re-Refined Engine Oil Bottoms
Publisher: American Society of Civil Engineers
Laboratory Performance of Asphalt Mixtures Containing Recycled Asphalt Shingles, Reclaimed Asphalt Pavement, and Recycling Agents
Publisher: American Society of Civil Engineers
Abstract: As the price of liquid asphalt continuously climbs, methods are being sought to decrease material costs without compromising material or pavement performance while having a positive influence on sustainability. One potential ...
Quantitative Effect of Elastomeric Modification on Binder Performance at Intermediate and High Temperatures
Publisher: American Society of Civil Engineers
Abstract: An experimental study was conducted to characterize the dynamic mechanical properties of elastomer-modified asphalt binders at intermediate and high temperatures. Two types of elastomeric modifiers, styrene-butadiene-styrene ...
Characterization of HMA Mixtures Containing High Reclaimed Asphalt Pavement Content with Crumb Rubber Additives
Publisher: American Society of Civil Engineers
Abstract: The objective of this study was to evaluate the use of crumb rubber (CR) from waste tires and engineered additives as a rejuvenator to high reclaimed asphalt pavement (RAP) content asphalt mixtures. Six asphalt mixtures ...
Laboratory Performance Characteristics of Sulfur-Modified Warm-Mix Asphalt
Publisher: American Society of Civil Engineers
Abstract: The objective of this study was to compare the laboratory mechanistic properties of sulfur-modified warm-mix asphalt (WMA) with conventional asphalt mixtures. Three mixtures, two hot-mix asphalt (HMA) and one WMA, were ...
