Modifying asphalt binder with styrene butadiene rubber (SBR) improves low temperature performance (resistance to cracking), elastic recovery, and ductility of binder. However, some difficulties were found at high temperatures susceptibility (Rutting), storage stability (compatibility). Therefore, the aim this study is resolve these defects (rutting compatibility) by formulating SBR/ waste nanoc...

Ethylene Propylene Diene rubber (EPDM), is present in many applications. However, its crosslinked structure makes difficult recycling. The use of devulcanized EPDM, (dEPDM) as a component elastomeric composites, real possibility to reuse EPDM scraps. In this study, three matrices (natural (NR), styrene butadiene (SBR) and rubber) have been tested including recycled component. previously was usi...

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...

In this paper, micro-mechanical properties of styrene–butadiene rubber (SBR) latexmodified cement pastes identified by means of the nanoindentation (NI) technique are related to macro-mechanical properties of SBR latex-modified mortars obtained from standard test methods, considering an SBR latex/cement ratio varying from 0% to 20%. For this purpose, the average value of the hardness and the so...

Dynamic nuclear polarization (DNP) at low temperature (1.2 K) and high magnetic field (3.3 T) was applied to a contrast variation study in small-angle neutron scattering (SANS) focusing on industrial rubber materials. By varying the scattering contrast by DNP, time-of-flight SANS profiles were obtained at the pulsed neutron source of the Japan Proton Accelerator Research Complex (J-PARC). The c...

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...

Extending the mechanical lifetime of NBR (i.e., poly(acrylonitrile-co-butadiene)), a large-volume synthetic rubber, requires better understanding its structure–property relationships. We demonstrate that industrial-grade and uncross-linked can be mechanically rejuvenated physically aged due to an inhomogeneous distribution monomers along polymer chains. As opposed nonpolar SBR counterpart poly(...

Nylon 6, 6 is regarded as tough and ductile materials since it exhibit high tensile elongation to break and high drop weight impact strengths. However, under conditions of stress concentration such as in the presence of sharp notches or cracks, polyamides exhibit brittle failure. This property, evaluated as notched Izod or Charpy impact tests, indicates that unmodified polyamides exhibit relati...

Asphalt materials have a very wide range of applications in roads, but with the increase traffic pressure and intensification cracking rutting traditional asphalt pavements, there is an urgent need to further improve performance materials. In this paper, composite containing 10%, 20%, 30% trinidad lake (TLA) 0%, 2%, 3%, 4% styrene-butadiene rubber (SBR) were prepared. Their basic properties mix...
