In this research the types of sample were asphalt mixture with 5% glass, 5% plastic, 2.5% glass and 2.5% plastic; 4% plastic and 1% glass; and 1% plastic and 4% glass. Marshall stability and flow results showed an excellent prospects using 5% plastic in asphalt concrete. The adapted results are given in Table 3.
Bitumen (or asphalt binder) is a by-product of the petroleum industry obtained by distillation of crude oil. It possesses valuable characteristics including long durability, high adhesion and water proofing abilities, which opened its ways for utilization as a road construction material [].In road construction, the bitumen is mixed with …
According to Hossain's UTA web page, each recycled pin utilizes about 500 plastic soda bottles. At one of the demonstration sites, Hossain's research group put 600 plastic pins into the ground, making use of 300,000 plastic bottles that otherwise would have ended up in landfills. Hossain thinks that the Chinese government's recent decision to ...

Recycling plastic wastes in asphalt pavement is a possible approach to reducing environmental pressure and the demand for depleted natural resources. Many studies have proposed recycling...
Low melting point plastic, such as LDPE and PP, is typically used as a bitumen modifier and incorporated in asphalt via the wet method by blending plastic with hot bitumen resulting in the formation of a polymer network into the bitumen matrix (Nizamuddin et al., 2020).Hence for asphalt modified via the wet method, most plastic …
A second, ongoing study with the National University of Singapore # is developing and evaluating the use of plastic-bituminous composite asphalt mixes. This new recipe incorporates local waste …
In order to compute the composition of crumb rubber modified bitumen (CRMB), the adopted materials were subjected to the relevant experiments. PCA was a very effective material when compared to the standard bitumen road pavement. The recycling of waste crumb rubber and plastic was tested by adding them into the hot mix …

1. Plastic Composite Roads. The general process to make and lay these roads might be the collection, sorting, cleaning, shredding, and melting of post consumer plastic, and then mixing/blending it with bitumen and aggregates. This asphalt mixture can then be laid as regular asphalt concrete might be. 2.
