Dynamic Mechanical Moduli of Residual Softwood-Filled Polystyrene

Mahmoud A.‐Halim Abdel‐Goad · المجلة العُمانية للبحوث الهندسية · 2009 · 10.24200/tjer.vol6iss1pp59-65

Residual softwood sawdust (RSS) was added to polystyrene (PS) that has molecular weight 280000 g/mol. The PS composite was prepared by melt mixing technique. The dynamic mechanical tests are carried out using ARES-rheometer (Rheometric Scientific, USA) in the dynamic mode and parallel plate geometry with diameter 25 mm …

Waste Plastic-Modified Bitumen: Rheological Study

Mahmoud A.‐Halim Abdel‐Goad · المجلة العُمانية للبحوث الهندسية · 2009 · 10.24200/tjer.vol6iss1pp76-81

Bitumen blends were prepared for road applications by the introduction of 9% of waste Polyethylene by weight (9 wt%). The relaxation stress, relaxation and retardation spectrum and viscosity of bitumen blends were studied at different temperatures and compared to those of the original pure bitumen. These properties wer …
