To achieve better performance, researchers have actively attempted to use different types of additives to improve the performance of asphalt mixtures, such as crumb rubber, polymers, or natural rubber [6–8].
Many researchers showed that fibers could improve the low-temperature performance and fatigue life of virgin asphalt mixtures [9, 10 Author: Yuefeng Zhu, Yanwei Li, Chundi Si, Xiaote Shi, Yaning Qiao, Haoran Li. Anchor: #i Section 6: Hot-Mix Asphalt Pavement Mixtures Anchor: #i General. Hot-mix asphalt (HMA) is a generic term that includes many different types of mixtures of aggregate and asphalt cement (binder) produced at elevated temperatures (generally between ºF) in an asphalt.

Asphalt Mixture Design and Performance Properties by Using a Gyratory Compactor (RES) Research Background. The Superpave mix design was developed in early s during the Strategic Highway Research Program (SHRP) () to replace the Hveem and Marshall mix design methods.
It is one of the primary outcomes from the SHRP study. Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, as well as the core of embankment dams.
Asphalt mixtures have been used in pavement construction since the beginning of the. Stone matrix asphalt (SMA) is a gap-graded bituminous mixture which can be used in surface layer of high volume pavements.
The mixture has higher concentrations of coarse aggregates, providing strength and rut resistance to the mixture, and higher asphalt content giving durability. There must be a proper stone-to-stone contact between the coarse aggregates of SMA, and hence Cited by: 7.
