CLSM as a highway construction material is becoming more widespread throughout the United States.Data received from questionnaires sent by the Pennsylvania Department of Transportation in 1991 and the Transportation Research Board (TRB) in 1992 indicated that approximately 30 states had some experience with the use of flowable fill, and at least 24 states have a specification for flowable fill.
Plastic is the generic name for a family of synthetic materials derived from petrochemicals. It is often product of two or more components. It is often product of two or more components. There are many families of plastics and polymers being used in construction industry, such as acrylics , composites , expanded polystyrene , polycarbonates ...
As a comparison, plastic road claims to dispose 8–10 kg (or 4-6%) of selected and washed plastic waste in the road surface per tons of asphalt, [4] while waste light concrete can dispose around 800 kg / tons of road base concrete with only low energy consumption shredding and mixing at room temperature. However, these two technologies can be ...

In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below). For example, a 25-foot (7.6 m) three-axle dump truck would have a gross weight limit of 54,500 pounds (24,700 kg), instead of 80,000 pounds (36,000 kg), which is the standard weight limit for 63-foot (19.2 m) five-axle tractor-trailer.

The Drucker–Prager yield criterion [1] is a pressure-dependent model for determining whether a material has failed or undergone plastic yielding. The criterion was introduced to deal with the plastic deformation of soils. It and its many variants have been applied to rock, concrete, polymers, foams, and other pressure-dependent materials.
