Abstract Rubber-soil mixtures are known to have mechanical properties that enable their use in backfills, road construction or geotechnical seismic isolation systems. The complexity of these comes from adding soft (i.e. rubber) particles increases the number particle consider when studying macroscopic behaviour. distinction between sand-like and rubber-like behaviour is normally presented relat...

in this study an empirical model which can be used to predict the rutting parameter (g*/sinδ) for neat and powder rubber modified bitumen describes. the model was developed using 36 unique powder rubber modified bitumen combinations, rubber concentrations were varied at 5% intervals between 5 and 20%. the effects of powder rubber particle size on model accuracy were also studied ultimately a mo...

The paper presents the results of comparison quality indices brake shoes for railroad rolling stock made synthetic cast iron smelted in induction furnaces and composite material which is a vulcanized mixture rubber different fillers. Disclosed are disadvantages pads. Defects working surface railway wheels caused by application pads rubber-asbestos or shown. Parameters C, Si, Mn, P, S content ca...

Each year, the number of scrap tires disposed in huge piles across world continuously increases. Consequently, new recycling solutions for these materials have to be proposed. Among them, one possibility consists shredding and mixing obtained tire chips with sand, which can used as alternative soils various geotechnical applications, such backfilling retaining structures, slope highway embankme...

This project’s goal was to mimic the Saharan silver ant’s micro-hair arrays by creating a solar heat reflecting membrane with parallel-aligned Al-ZnO microrods using Mayer rod coating method. The synthesis of carried out hydrothermal then produced mixing liquid silicone rubber and spreading mixture into shape rod. dragging microrod, confined between polypropylene film, induces partial alignment...

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....

Including food production in non-food systems, such as rubber plantations and biofuel or bioenergy crops, may contribute to household food security. We evaluated the potential for planting rice, mungbean, rice cultivar mixtures, and rice intercropped with mungbean in young rubber plantations in experiments in the Arakan Valley of Mindanao in the Philippines. Rice mixtures consisted of two- or t...
