A laboratory study on stone matrix asphalt using ground tire rubber

Experimental investigation on mineral and organic fibers effect on resilient modulus and dynamic creep of stone matrix asphalt and continuous graded mixtures in three temperature levels

“…Same fiber (COPF) was used and compared with Ethylene Vinyl Acetate (EVA) as selected asphalt modifiers in other study [13]. Tire rubber was used in a laboratory study to investigate moisture susceptibility and rutting resistance of stone matrix asphalt [4]. Polyester, Polyachrilonitrile, Lignin and Azbestus fibers used in asphalt mixtures to evaluate marshal stability and air voids in mixtures after these fibers were added to asphalt mixture in a research.…”

“…Such movements are resulted from very hot weather or inadequate compaction of material in construction process [3]. Several studies have shown using SMA on road surface can achieve better rut resistance and durability [4].…”

Performance improvement of a crumb rubber modified bitumen using recycled glass powder

“…For instance, CR can be used as a bitumen modifier instead of expensive polymers such as styrene butadiene styrene (SBS) and styrene butadiene rubber (SBR) to reduce construction costs and energy consumption. This technique can also help reduce environmental pollution by recycling waste tires (Chiu and Lu, 2007;Lee et al, 2008). Interestingly, in addition to the above-mentioned benefits, the combination of CR with bitumen improves the performance and engineering properties of asphalt pavements (Chiu and Lu, 2007;Santagata et al, 2007;Canestrari et al, 2009;Cao, 2009;Kaloush et al, 2009;Partl et al, 2010).…”

Asphalt Pavement Material Improvement: A Review

“…This will therefore decrease in voids preventing the moisture absorption and oxidation (by air/water) of the asphalt. Chui-Te Chiu and Li-Cheng Lu, (2007) have used asphalt rubber, produced by blending ground tire rubber (GTR) i) 30% of a coarse GTR with a maximum size of #20 sieve and ii) 20% of a fine with a maximum size of #30 sieve with an asphalt, as a binder for SMA and found AR-SMA mixtures were not significantly different from conventional SMA in terms of moisture susceptibility and showed better rutting resistance than that of conventional dense graded mixture [79]. A set of laboratorial tests were done using CR, obtained by ambient grinding, with conventional asphalt commercially named CAP-50/70.…”
