Influence of clay nanoparticles on the physical and rheological characteristics of short term aged asphalt binder

This research paper presents laboratory investigation on the physical and rheological properties of asphalt binder modified with Organic Montmorillonite Nanoclay (OMMT). Two different concentrations (1% and 7% by weight of base asphalt) of OMMT was selected toblendwith80/100 penetration grade asphal...
