Cracking potential of short- and long-term aged binder with various levels of ABR
It is widely accepted that using reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) could improve the sustainability of asphalt concrete (AC), in terms of cost savings and environmental factors. This should be only valid when short- and long-term pavement performance are not …

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 …

Performance analysis of asphalt mixtures modified with ground tire rubber and recycled materials
… research has been done on rubber-modified asphalt due to its distinct performance benefits, resulting in advancements in the existing rubber modifier technologies. This study focuses on two such new rubber-modifier technologies- an Engineered Crumb Rubber (ECR), and a terminal-blend Rubber …

An analysis of impact factors on the Illinois flexibility index test
The use of recycled materials in asphalt pavements has become widespread in recent years. Materials such as recycled asphalt pavement (RAP) and recycled asphalt shingles (RAS) have been incorporated into the material design of typical pavements. The use of these materials is both economically and …

Balancing asphalt mixes containing recycled materials for optimum field performance
Asphalt concrete (AC) is the most common material used for the construction of pavements in the U.S. and many other countries in the world. With the increasing use of recycled materials like reclaimed asphalt pavement (RAP) and recycled asphalt shingle (RAS), the cracking resistance of asphalt …

Impact of recycled asphalt shingles on asphalt concrete characteristics
The use of recycled materials in asphalt mixtures such as reclaimed asphalt pavements (RAP) and more recently recycled asphalt shingles (RAS) have become widely accepted in the United States as a replacement for virgin asphalt binder or virgin aggregates. However, the economics and the challenges …

Evaluation of viscous effects in crack tip fields in recycled asphalt pavement materials using digital image correlation
… work, we investigated the fracture behavior of asphalt, a heterogeneous mixture of hard aggregates (usually rock) with a polymeric binder (also called asphalt), used in paving applications. Specifically we studied the dependence of asphalt fracture response on loading rate, temperature, and …
