2. What is plastic welding
Plastic welding is the process of creating a molecular
bond between two compatible
thermoplastics. Welding offers superior strength, and
often drastically reduced cycle times, to mechanical joining
(snap fits, screws) and chemical bonding (adhesives).

19. PLASTIC ROAD
Plastic roads are roads made either entirely of plastic or of composites of plastic with other
materials. Plastic roads are different from standard roads in the respect that standard roads are made
from asphalt concrete, which consists of mineral aggregates and asphalt. This technology is getting
replicated very fast in Jharkhand, after the plastic road laid at Jamshedpur city on 30th November
2011. Many counties like Nigeria, Australia, Kenya etc. and the Indian cities like Ranchi, Bokaro,
Dhanbad.
Since plastic roads are a relatively new idea, construction processes may vary. In Jamshedpur, India,
roads are created from a mix of plastic and bitumen. . The plastics involved in building these roads
consists mainly of common post-consumer products such as product packaging. Some of the most
common plastics used in packaging are Polyethylene Terephthalate(pet Or Pete), Polyvinyl
Chloride(pvc), Polypropylene (Pp), and high and low density polyethylene (HDPE and LDPE).
These materials are first sorted from plastic waste. After sorting, the material is cleaned, dried, and
shredded. The shredded plastic is mixed and melted at around 170°C.
