Polystyrene used for Road Embankment Construction

Date_ 17 October 2018

Poor ground conditions on a section of the Colley Lane site in Somerset meant that innovative solutions were sought to overcome the ground condition.

Conventionally quarry products would be used for constructing embankments, however the project designers selected lightweight, high density Polystyrene Blocks to create 300m of the road embankment between the Somerset and Crossways Bridges. The adoption of a low ground bearing pressure solution was the preferred solution after a detailed consideration of several options.

This method of construction will prevent additional loading on the existing ground and also reduce the number of vehicular movements to site by 90% which means nearly 500 truck deliveries less to and from site.
