Quantification and Characterization of Fracture Resistance in Asphalt Concrete Based on R-Curve Method
… the internal factors of aggregate size and binder grade, and the external factors of testing temperature and loading rate. The effects of aggregate size, binder grade, temperature, and loading rate on crack initiation and propagation are found by the parameters of cohesive energy and energy …

Impact of reclaimed asphalt pavements on pavement sustainability
… (RAP), being a source of aggregates and asphalt binder, is the most recycled material in the U.S. However, incorporating high amount of RAP in asphalt mixtures can pose significant mix design issue and could compromise the pavement performance. Technical complications aside, for RAP to be …

ANALYTICAL MODELING OF RUTTING POTENTIAL OF ASPHALT MIXES USING HAMBURG WHEEL TRACKING DEVICE
… mixture type, gradation, aggregate type, binder type and so on. There is no complete research in the literature which examined all these factors at the same time. This study evaluated the above mentioned factors in the deformation behavior of AC. Thin AC cylindrical samples were prepared …

Influence of Recycled Asphalt Shingles on Asphalt Binder Content, Mixture Stiffness, and Laboratory Rutting Performance
… effects of recycled asphalt shingles on asphalt binder content, mixture stiffness, and laboratory rutting performance. For this project, shingles were added to hot mix asphalt mixtures at 2.5, 5, and 10 percent by weight of the total mix. This study showed that incorporating shingles into mixes …

Developing pavement preservation and mitigation strategies using Pavement ME design guide for Rhode Island DOT
… hot mix asphalt (HMA) layers, traffic volume, binder grade of the surface HMA layer and the base layer modulus. The surface HMA layer thickness and traffic volume were significant at 95% confidence level for both types of rutting and terminal IRI. The existing HMA layer thickness was …

The Effects of Reclaimed Asphalt Pavement (RAP) on the Laboratory Performances of Hot Mix Asphalts
… mix design 19 mm mixture containing 0% RAP with binder grade of PG64-22 and PG64-28NV were used as the control mixtures for evaluating properties of mixtures containing 15% and 30% RAP for three different sources of RAP which include one fresh plant waste RAP material.The effects of RAP on the …

Evaluation of binder grades on rutting performance
… Highways, WVDOH, has implemented the Performance Grade binder specifications for all paving projects and Superpave for high volume road projects. The standard binder specified in the state is a PG 64-22; for high volume roads a PG 70-22 is specified. These binders appear to be working well for …

Quantification of the Role of The Effective Binder in the Performance of RAP – WMA Mixtures
… (such as WMA, RAP, rubber, polymers, bio-binders…etc.) were incorporated into asphalt mixtures. However, current mix-design specifications evaluate all mixtures containing these different additives/technologies based on volumetric. Further, RAP incorporation in asphalt mixtures is still …
