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...

Waste tyre-rubber disposal is a serious global problem, posing severe danger to the environment. This present study aims investigate performance of concrete utilizing recycled waste as partial replacement for natural fine aggregate. Three different sizes crumb rubber were combined produce well-graded sample. Based on various trials, mixed proportions M30 grade and percentages determined. The te...

Abstract Designing mixtures of asphalt with a porous structure to gain good trainability decreases both the propagation and generation traffic noise. Porous (PA) use crushed stone, small proportion processing sand, admixtures, binders. Therefore, this study aims examine impact adding crumbed rubber into mix PA. However, optimum amount binder used in reference mixture without crumb (CR) 10, 15, ...

Aim of this work was to investigate the tensile, flexural and dielectric properties of composites made by reinforcing Sansevieria cylindrica as a new natural fibre into a rubber based polyester matrix. The fibres extracted by retting and manual processes were used to fabricate the composites. These composites were tested for the properties which mentioned above and compared with those of establ...
