The performance of Styrene-butadiene-styrene (SBS) modified asphalt is closely related to the content SBS modifier. In production process asphalt, a certain amount additive such as sulfur and rubber oil may be added reduce segregation promote swelling polymer, but effect these additives on determining in not yet clear. This paper presents calibration curves based rutting factor creep slope poin...

Abstract The objective of our experiment was to investigate the rheological properties a compound coating depending on pre-treatment temperature regimes. Compound samples were measured at six different temperatures with 2 °C resolution between 40 and 50 °C. One part melted by RV1 rotational rheometer actual melting other filled into 9 × mm cubes molds. These cooled 24 h in freezer (−18 °C) next...

To understand the long-term self-association of gum arabic (GA) in water, time-course development during aggregation GA molecules with or without an oil/water interface was studied. A simple experimental setup, using a rheometer employed. The transparent cone-plate geometry filled solution, and periphery covered oils left uncovered. observed increase shear modulus revealed that continuous struc...

acrylamide was grafted in low density polyethylene during melt processing in the presence of a free radical initiator using a torque rheometer in a closed system. effects of processing time, acrylamide and benzoyl peroxide concentrations were studied. ftir studies revealed that the degree of grafting increased by an increase in acrylamide concentration. maximum grafting was obtained at 7 minute...

This study treats one important aspect of starch-filled rubber compounds which is their rheological behavior. Starch-based SBR1712 masterbatches resulting from various formulations were prepared using a mini two roll mill and an internal mixer (Plastograph Brabender).The content in starch was varied from 0 to 50 phr. The effect of starch content on the rheological behavior was ev...

This study investigated the impact of using modified bitumen binders and additives to enhance physical characteristics asphalt mixtures at high, medium, low temperatures. Both basic rheological bituminous were tested by adding Styrene-Butadiene-Styrene, a type thermoplastic elastomer, as chemical additive various fractions (3.5%, 4%, 4.5%), two kinds Bitumen: Kraton styrene block copolymers Eur...
