Abstract Crumb rubber (CR) is generated from the recycling of used or discarded car tires and has long been utilized in paving industry. can be asphalt mixes two ways: dry process wet process. However, compared to standard combinations, crumb modified (CRMA) requires much higher mixing compaction temperatures. As a potential substitute, using warm mix (WMA) technology significantly lower hot-mi...

coeffcient of  friction  (cof)  for  rubber parts  is one of  the key parameters in their interaction with solid rough surfaces (micrometer to millimeter scales),  such  as  tire-road  interactions. cof  of  rubber  depends  on  viscoelastic properties of rubber, roughness characteristics of the counter-part surface, and process variables such as contact nominal pressure and sliding speed. due ...

A comparative study on biodegradation of di-cumyl peroxide (DCP) crosslinked and uncrosslinked natural rubber by Pseudomonas sp. was carried out. Decrease in organic carbon content along with the changes in tensile strength of the treated rubber, both DCP crosslinked and uncrosslinked natural rubber, indicated rubber hydrocarbon utilization by the Pseudomonas sp. A decrease in 60.88% MPa and 41...

Crumb rubber is basically tiny particles produced from scrap vehicle tires. This crumbled into uniform with the help of shredders. In present work, an attempt has been made to utilize as a partial substitute fine aggregates in fabricating cement concretes. Concrete mixture cement, coarse aggregates, and water. Rubber size ranging between 0.297 0.250 mm are used proportion 5, 10 15% by weight pa...

The objective of this study is to compare the long-term aging performance dry-processed rubber-modified asphalt mixture with styrene–butadiene–styrene polymer-modified on heavy traffic volume roads in wet-freeze environment Michigan. rutting was evaluated using Hamburg wheel track device. disc-shaped compact tension test used assess fracture energy. dynamic modulus experiment estimate load and ...

This paper presents the results of consolidated and undrained (CU) triaxial cyclic tests related to influence tire waste addition on strength characteristics two different soils from Southern Poland: unswelling kaolin swelling red clay. The test procedure included normally remolded specimens prepared pure clay (RC) (K) their mixtures with fractions shredded rubber powder (P) granulate (G) in 5%...

Warm Mix Asphalt (WMA) is a good pavement option due to its environmental benefits. Short-term aging one of the critical factors that WMA should carefully study. This research aims study effect short-term on warm mix asphalt has different percentages rubber. In this study, three rubber (1, 1.5, and 2%) by weight aggregate are considered be added WMA. By use Indirect Tensile Strength test for HM...

There have been no reports of the simultaneous application natural fillers, such as magnetite and zeolites, to increase strength composites containing silica (SiO2) fillers reinforcing in rubber. This study has investigated effect magnetically modified zeolite on nanosilica-reinforced rubber that include a mechanical characteristic like human tissue. We use technical specifications (TSR) SIR 20...

since reusing waste tire as a cheap filler is considerably high, in this study, recycled rubber to replace nr/br is used up to 15 phr and the positive and negative aspects of the rubber powder and reclaimed rubber in the physical, dynamical and processing properties are evaluated. the results showed that in the presence of recycled rubber, the cure rate, crack growth resistance, tear strength a...
