Laboratory Evaluation of High Asphalt Binder Replacement with Recycled Asphalt Shingles (ras) for a Low N-design Asphalt Mixture
This study investigated the effect of high asphalt binder replacement for a low N-design asphalt mixture including RAP and RAS on performance indicators such as permanent deformation, fracture, fatigue potentials, and stiffness, was studied. An experimental program included complex modulus, fracture, overlay reflective cracking resistance, wheel track permanent deformations, and push-pull fatig...
متن کاملCharacterization and Micromechanical Investigation of Recycled Asphalt Shingle Binder Blends
The sustainability movement has established a firm foothold in the Civil Engineering profession. The use of recycled asphalt shingles (RAS) is the latest development in the world of asphalt pavement sustainability. The relative abundance of tear-off shingles and their high asphalt content is driving RAS usage in highway and airfield pavements. However, the ultimate objective of any pavement sys...
متن کاملResearch on Design Technology of TLA Modified Asphalt Mixture
Marshall Test design methods are used to design TLA modified asphalt mixture and base asphalt mixture respectively, and their pavement performance is tested. The results showed that there is a transforming coefficient of 1.15 between OAC of 40% TLA modified asphalt mixture and that of base asphalt mixture, and ultimate gradation of the TLA modified asphalt mixture is finer than previous gradati...
متن کاملDevelopment of Recycled-Modified Asphalt Using Basalt Aggregate
With the strengthened regulation on the mandatory use of recycled aggregate, development of construction materials using recycled aggregate has recently increased. This study aimed to secure the performance of asphalt concrete mixture by developing recycled-modified asphalt using recycled basalt aggregate from the Jeju area. The strength of the basalt aggregate from the Jeju area used in this s...
متن کاملPerformance of Recycled Asphalt Shingles in Hot Mix Asphalt: TPF-5(213)
US transportation agencies have been increasingly using recycled asphalt shingles (RAS) in hot mix asphalt (HMA) applications over the last 25 years. Initial use of RAS started with recycled postmanufacturers shingles, but now agencies are showing a growing interest in using post-consumer (tear-off) RAS in asphalt applications. Post-consumer asphalt shingles typically have 20 to 30 percent asph...
