The applications of rubber-modified asphalt and its mixtures have received widespread attention due to the environmental economic benefits such materials. However, studies on structural performance rubber-powder-modified pavement are only concentrated a certain scale, leading research mostly focusing mechanical responses at macro scale. Therefore, present study adopts concept multi-scale analyz...

To solve the problems of storage stability and volatile organic compound emission waste-rubber-powder-modified bitumen, strategy preparing composite modifiers using waterborne polyurethane coating for waste rubber powder was proposed in an early-stage work. However, effect polyurethane/waste modifier on performance asphalt mixture is unclear, which limits further popularization this technology....

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%...

The strength comparison of fibre reinforced peat and clayey-silt for the compacted sub-grade by using reinforcement technique from scrap tire is presented. tires are extracted shredded into a standard size, i.e., rubber-chip, rubber-crumb, rubber-powder fibre-polyester consistency homogeneity design mix. In this study, two types fibres used, which polyester rubber crumb. at various designated p...

Introduction: Air-powder polishing devices are increasingly used for stain and plaque removal. However, besides cleaning the tooth surface, they may increase the surface roughness of the dental tissues. This in turn may result in plaque accumulation and superficial degradation. Thus the aim of this study was to assess the influence of three different abrasive agents: Pumice, Sodium bicarbonate ...

This study presents an alternative for the combined revalorization of two wastes with high volumes generation, such as end-of-life tyres and glass. The experimental grid considered analysis joint use crumb rubber glass powder in mortars. Crumb is analysed a sand replacement at 10% 15% percentages, while is'. cement, considering effect maximum size particles (38 μm 45 μm). results obtained show ...

This is a word of caution to anyone using ionization chambers protected by thin rubber sheaths in water. Four Farmer-type ionization chambers contaminated with talcum powder were received for calibration by the Accredited Dosimetry Calibration Laboratory at the University of Texas M. D. Anderson Cancer Center. The chambers show a marked energy dependence (5% to 20%) to soft orthovoltage x rays....
