Using Polyphosphoric Acid and Sulfur to Improve Storage

In this study, the base asphalt binder was modified by using 3 and 7 % high-density polyethylene (HDPE). Subsequently, 1.5 % polyphosphoric acid (PPA) and 0.5 % sulfur were combined with polymer-modified asphalt binder to improve the stability between asphalt binder and polyethylene as well as reduce phase separation.

Performance evaluation of Al2O3 nanoparticle-modified

The rheological and physical properties of asphalt binders modified with aluminium oxide (Al 2 O 3) nanoparticles were investigated.Al 2 O 3 nanoparticles were added to the base asphalt binder at concentrations of 3, 5, and 7 wt.%. Superpave binder tests were conducted to evaluate the characteristics of the nano-Al 2 O 3-modified binders.Rotational viscosity tests and a dynamic shear rheometer

PDF Viscosity evaluation of asphalt binders containing

This study presents an experimental evaluation of viscosity changes in asphalt binders containing petroleum resin. Petroleum resin (PE) as one of the tackifier polymers has been considered to conduct this viscosity measurement in asphalt binders. PG 64-22 and PG 76-22 asphalt binders were modified using three PE contents of 0%, 5% and 10%.

Polymer-Modified Asphalt 101

For asphalt cements: The dispersion of the relatively aromatic, polar, associating molecules in a less aromatic, less polar solvent phase. – For Polymer Modified Asphalt Cements: The extent of dispersion between the asphalt cement and the modifier. This determines to a large extent the physical properties of the binder.

Characterization of Alaskan modified asphalt binders and

Modified asphalt binders and mixtures have been used more in recent years in Alaska. However, there has not been systematic characterization and performance data development for these materials. This study intends to systematically characterize the Alaskan asphalt binders and mixtures and identify the performance benefits of these materials through laboratory tests and field sections monitoring.
