Lime Treatment at the A282/A2 Junction

The McArdle Group were contracted to carry out the lime modification of site won chalk. This involved reducing the moisture content of approximately 300,000 m3 of chalk with lime, a quantity larger than any in recent years.

The treated materials were then placed as suitable fill adjacent to the M25. The works were carried out in 12 weeks by the main contractor for the Highways Agency.
