·exploration for potential use as an ingredient in asphalt mixtures especially the synergy between polymer modification and fly ash particles The blend of bitumen and finely divided spherical particles create a dense mix referred to as mastic Since the early 1900 s [Richardson 1905] it was noted that the use of
"Asphalt has a polymer type network that is unique " Usmani says Although not a polymer in the strict sense of the word it is a thermoplastic material it softens when heated and hardens upon cooling Within a certain temperature range an asphalt is also viscoelastic which means that it exhibits the mechanical characteristics of viscous flow
·Asphalt Ingredients There are actually two basic Ingredients in Asphalt The first is Aggregates This is a mix of Crushed Stone Gravel and Sand Aggregates make up about 80% of Hot Mix Asphalt pavement The other 20% is Bitumen Bitumen is the Black or Dark Viscous material that holds the Aggregates together and is composed of Polycyclic
