EVALUATION OF RECYCLED ASPHALT MIXTURE TECHNICALLY AND ECONOMICALLY

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...

Evaluation of the Effects of Recycled Asphalt Pavement (rap) on an Ndot Hma Mixture

Evaluation of the Mechanical Properties of the cement treated Cold-in-Place Recycled Asphalt Mixtures

Cold-in-place recycling (CIR) is an environmentally sustainable alternative for preservation of asphalt pavements. A major disadvantage of this practice is the lower strength of the cold-in-place mixtures. Addition of cement into this type of mixture is a method for increasing its bearing capacity. The effect of cement content on the mechanical properties of the cold-in-place recycled asphalt m...

Use of Recycled and Waste Fibers in Asphalt Concrete

A significant problem associated with asphalt concrete mixtures is the lack of durability resulting from an inadequate asphalt cement content. Additional asphalt cement added to increase durability results in flushing, bleeding and a significant loss In stability. Fibers have been used in stone matrix asphalt and open-graded friction course pavements successfully throughout Europe to allow high...

Characterization 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...
