TLDR
In this article, the authors investigated the benefits of stabilizing the SMA mixture in flexible pavement with shredded waste plastic and found that 10% plastic content gives an increase in the stability, split tensile strength and compressive strength of about 64, 18% and 75% respectively compared to the conventional SMA mix.Abstract:
The present study investigates the benefits of stabilizing the stone mastic asphalt (SMA) mixture in flexible pavement with shredded waste plastic. Conventional (without plastic) and the stabilized SMA mixtures were subjected to performance tests including Marshall Stability, tensile strength and compressive strength tests. Triaxial tests were also conducted with varying percentage bitumen by weight of mineral aggregate (6% to 8%) and by varying percentage plastic by weight of mix (6% to 12% with an increment of 1%). Plastic content of 10% by weight of bitumen is recommended for the improvement of the performance of Stone Mastic Asphalt mixtures. 10% plastic content gives an increase in the stability, split tensile strength and compressive strength of about 64%, 18% and 75% respectively compared to the conventional SMA mix. Triaxial test results show a 44% increase in cohesion and 3% decrease in angle of shearing resistance showing an increase in the shear strength. The drain down value decreases with an increase in plastic content and the value is only 0.09 % at 10% plastic content and proves to be an effective stabilizing additive in SMA mixtures.read more

Utilization of polymer waste for modification of bitumen in road construction
TL;DR: In this paper, two types of techniques can be used for disposal of polyolefins waste in road construction: dry process and wet process, both of which require strong mechanical stirrer and continuous rotation, batch type production and separate chamber.
