In this paper, the effect of adding recycled glass powder (RGP) as a third component in polymer modified bitumen is studied. RGP and styrene butadiene rubber (SBR) is added to the base bitumen in order to prepare modified binders and mixtures. The initial study is performed to determine physical properties of unmodified, SBR modified and RGP-SBR modified asphalt binders which prove RGP's compat...

This presentation provides a brief overview of the production and use of 1,3-butadiene in the United States. Starting as a coproduct of ethylene, the 1,3-butadiene monomer is extracted and purified, then transferred to consumers. Major uses of 1,3-butadiene include the manufacture of styrene-butadiene rubber, polybutadiene rubber, and adiponitrile.

1,3-Butadiene is a highly volatile gas that is used in the production of synthetic rubber; the major end use of the synthetic rubber is automobile tires. 1,3-Butadiene is also used for the production of high impact polystyrene and acrylonitrile-butadiene-styrene (ABS) resin plastics The predominant source of 1,3-butadiene in the atmosphere is industrial releases, which can occur during manufact...

The dichotomy between mechanical performance and repairability is a well-known fact in the self-healing field. One alternative to overcome this trade-off inclusion of reinforcing fillers. In research, hybrid reinforced styrene-butadiene rubber (SBR) composites are developed by combining mechano-chemically modified ground tire (mGTR) with carbon black (CB). SBR matrix systematically analyzed mea...

A comparative study has been done to investigate the effect of carbon black (CB) and fumed silica (Si) on physico-mechanical thermal properties Bagasse/styrene-butadiene rubber (B-SBR) composites. Based incorporation 25 phr from natural ground bagasse powder (GBP) as a supplement reinforcing filler in styrene butadiene (SBR) vulcanizates, two identical sets formulations have prepared using diff...

In this research, the efficiency of Recycled Glass Powder (RGP) is evaluated for improvement of polymer-modified bitumen and asphalt mixture performance. An extensive laboratory programm was undertaken for polymer-modified bitumen including Crumb Rubber (CR), Styrene Butadiene Styrene (SBS) and Styrene Butadiene Rubber (SBR). Rheological and mechanical proper...

In road paving industry, asphalt emulsion is used for cold mix application such as chip seal, slurry seal, microsurfacing, cold recycled mixture and etc. Asphalt emulsion has several advantages compared to normal asphalt such as eco-friendly, easy to handle at ambient temperature and energy saving material because it does not need any heating process in its application. The history of asphalt e...

Kualitas dispersi bahan pengisi dalam karet sangat mempengaruhi sifat fisis dari vulkanisat karet. Metode baku pengujian silika (ISO 11345-2006) merupakan metode kualitatif sehingga hasilnya bersifat subyektif. Tujuan penelitian ini adalah menguji yang penggabungan mikroskop optik dan perangkat lunak ImageJ untuk mendapatkan secara kuantitatif. Alat dipergunakan mengevaluasi yaitu Arcs. Karet a...
