The Use and Performance of Asphalt Binder Modified with Polyphosphoric Acid (PPA)
Background The modification of asphalt binder to improve performance properties has grown significantly since the implementation of the Strategic Highway Research Program (SHRP) binder specifications. There has been increased use of polymers, crumb rubber modifier and Polyphosphoric Acid (PPA). There has been concern by many highway agencies about the performance characteristics of PPA modifica...
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 کاملApplication of SCB Test and Surface Free Energy Method in Evaluating Crack Resistance of SBS Modified Asphalt Mixes
Cohesion properties of the binder matrix within asphalt mixes and adhesion characteristics of the asphalt binder and aggregate particles are the two major mechanisms resisting against cracking in asphalt mixes. This study is focused on estimating crack resistance of asphalt mixes at intermediate temperatures through evaluation of cohesion and adhesion properties of binder-aggregate systems usin...
متن کاملFabrication, characterization, and microscopic imaging of Fe2O3-modified electrospun nanofibers
This study explored the fabrication, characterization, and microscopic imaging of highly porous electrospun nanofibers based on pure and Fe2O3 nanoparticle modified polyacrylonitrile (PAN) fibers. The desired electrospinning mixture comprising polymer and nanoparticles in dimethyleformamide, was prepared. During electrospinning, the precursor solution was injected using a ...
متن کاملNanoclay-modified asphalt materials: Preparation and characterization
The objective of this study is to review existing literature in the area of nano-modification of asphalt and proceed to apply nano-materials to asphalt to improve the performance. This study integrates literature review, preparation, and characterization of nano-modified asphalt materials. In the experimental testing montmorillonite, nanoclay at 2% and 4% by weight of asphalt was blended in asp...
