%X In this research for selecting best optimum linear low density polyethylene content for bitumen modification. 80/100 Pen bitumen were used as the control sample and linear low density polyethylene (LLDPE) were blended with 80/100 pen bitumen to prepare a modified mix. The concentrations of LLDPE polymer in the blends were 4, 5 and 6 by weight of bitumen. Conventional test which includes penetration, softening point, ductility, temperature susceptibility tests were conducted using the control 80/100 and LLDPE modified binders. Also storage stability test were conducted to access the stability of the control and LLDPE modified binder. The results indicate that 6 LLDPE modified binder offers the best results compared to control, 4 and 5 LLDPE modified binders when they were investigated in terms of conventional properties. Storage stability test result shows that phase separation might occur in all the polymer modified binders during storage or transportation especially at higher temperatures. © 2016 Taylor & Francis Group, London. %K Binders; Bituminous materials; Environmental engineering; Offshore oil well production; Phase separation; Polyethylenes; Polymer blends, Control samples; Modified binders; Polymer-modified binders; Softening points; Storage stability; Temperature susceptibility, Stability %O cited By 16; Conference of 3rd International Conference on Civil, offshore and Environmental Engineering, ICCOEE 2016 ; Conference Date: 15 August 2016 Through 17 August 2016; Conference Code:180169 %J Engineering Challenges for Sustainable Future - Proceedings of the 3rd International Conference on Civil, offshore and Environmental Engineering, ICCOEE 2016 %L scholars7604 %D 2016 %R 10.1201/b21942-80 %T Physical and storage stability properties of linear low density polyethylene at optimum content %I CRC Press/Balkema %A N.
