LITERATURE REVIEW The Use of Waste Plastics in Asphalt Mixtures

WebSep 12, 2024 · In polymer chemistry, the width of the distribution of molecular weights is described by the dispersity (Ð, also called, in older texts, the polydispersity or the polydispersity index, PDI). The dispersity of a polymer sample if often between 1 and 2 (although it can be even higher than 2). The closer it is to 1, the narrower the distribution. WebModifying asphalt mixtures using the addition of polymers and fibers has been shown to prolong service life and reduce maintenance, as well as provide improved bonding to aggregate particles (Ghuzlan, Al-Khateeb, & Qasem, 2015).
