Impact of laboratory simulated aging on asphalt concrete flexibility
The aging of asphalt materials is considered an important factor contributing to the deterioration of asphalt concrete (AC) pavements. Asphalt binder aging is a combination of various complex mechanisms that affect its rheological properties causing AC to become stiffer and more brittle. As a …

Linear viscoelastic characteristics of Michigan asphalt mixtures and the effect of sample size on material properties
… linear viscoelastic characteristics of asphalt mixtures and binders commonly used in Michigan. This is important for implementation of the M-E PDG in Michigan and for accurate prediction of flexible pavement distresses. The second objective was to develop analytical models in efforts to …

High Reclaimed Asphalt Pavement in hot mix asphalt
… the existing pavement, known as Reclaimed Asphalt Pavement (RAP) is ripped up, milled, and stockpiled and can be used in the creation of new mixes in order to save money and resources. New Jersey state specifications limit the percentage of RAP that can be used to 15% for surface courses …

Evaluation of interlayer bonding in hot mix asphalt pavements
… the level of interlayer bonding achieved in pavements. Data was obtained and used from the Federal Aviation Administration's (FAA) National Airport Pavement Test Facility located in Atlantic City, New Jersey. In this test facility, a section of the pavement had encountered a loss of bond …

Developing pavement preservation and mitigation strategies using Pavement ME design guide for Rhode Island DOT
… and Permanent Deformation (Rutting) in both the asphalt layer and the total structure were predicted using Pavement ME to determine the sensitivity of flexible pavement performance with varying pavement parameters, such as thickness of the surface and existing hot mix asphalt (HMA) layers, …

Evaluation of the degree of blending of Reclaimed Asphalt Pavement (RAP) binder for warm mix asphalt
… has seen the emergence of a plethora of warm mix asphalt (WMA) technologies and application. With most states incorporating a recycled asphalt pavement (RAP) limit, it is necessary for WMA to not only serve as a greener technology but to work in conjunction with current RAP practices. Presently, …

Correlation between multiple stress creep recovery (MSCR) results and polymer modification of binder
… loads are increasing, pushing conventional asphalt to its limit, while in New Jersey matters are made worse by the heavy use of the Northeast Corridor. Polymer modification of asphalt, which can improve both low and high temperature performance, is already available; however, but in many …

Stress Transfer and Structural Failure of Bilayered Material Systems
… adhesive anchors, (2) material coatings, (3) asphalt pavements, and (4) layered sedimentary rocks. The stress and displacement fields determined by this analytical analysis are validated through the use of finite element models. Through the correspondence principle, the linear-elastic solution …

Predicting failure behavior of polymeric and asphalt composites using damage models
… This study also predicts the failure behavior of asphalt materials through the use of damage models using the principles of the DSC. Traction-separation crack response, damage initiation and damage evolution behavior are investigated by modeling pavement systems consisting of a hot mix asphalt …

Laboratory investigation of fatigue endurance limits in asphalt concrete
It is believed that Hot Mix Asphalt (HMA) mixtures used in long-lasting pavements contain a threshold of strain value below which no fatigue damage occurs. This concept is known as the fatigue endurance limit (FEL). Although previous studies have shown that an endurance limit does exist for HMA …

Environmental analysis of using recycled asphalt shingles in pavement applications.
Recycled asphalt shingles have been used in paving applications for more than two decades and have growing acceptance in the industry. The cost of asphalt binder has steadily increased, fueling pressure to find suitable recycled materials to supplement virgin materials. The Minnesota Department of …

Development of a pavement life cycle assessment tool utilizing regional data and introducing an asphalt binder model
… be used to measure the environmental impacts of pavements. A LCA framework for pavements is developed to evaluate the environmental burdens of five phases in the life cycle: material production, construction, maintenance, use, and end-of-life. The framework is incorporated into a user-friendly …

Alternatives to PCI and MicroPAVER based maintenance solutions for airport pavements
Airport pavements need to be maintained for adequate health condition by implementing cost effective maintenance solutions. Traditionally, maintenance and repair techniques have been developed based on the minimum acceptable Pavement Condition Index (PCI). However, there are pavements which show …

Development of a phenomenological constitutive model for fracture resistance degradation of asphalt concrete with damage growth due to repeated loading
Discontinuous areas under the asphalt concrete (AC) layer, such as joints and cracks in an underlying layer, induce higher stress concentration than the designed strength. Stress concentration in the vicinity of discontinuities accelerates distress on the AC layer. Repeated traffic and …

The effect of mica on the aging of asphalt binder
Asphalt Concrete (AC) consists of approximately 95% aggregate, by weight. Of this 95%, about 6% is smaller than 0.075 mm in size (passing the #200 sieve and called fines). The fines often contain mica. Mica is a formation of silicate minerals having perfect basal cleavage. It can be peeled apart in …

Evaluation of selected airport pavements in New Mexico
Rehabilitation of poor conditioned airport pavements can be very expensive compared to the rehabilitation of relatively good conditioned airport pavements. Determining the conditions of airport pavements is a first step to determine appropriate rehabilitation method and timing. In this study, the …
