Lime modification at N4 Collooney to Castlebaldwin Road Improvement project

We’re currently working with Oliver Conroy Plant & Agri Hire and Roadbridge on the design and reporting of lime modification of cohesive soils at the N4 Collooney to Castlebaldwin Road Improvement site.

Pulverisation and rolling of lime treated soil

Treatment with lime is allowing unacceptable Class U1 material be processed to acceptable Class 2 general fill, allowing efficient and sustainable reuse of local soil which may have been disposed of as a waste. This process also saves on importation of suitable fill from elsewhere, dramatically reducing road haulage movements and hence disturbance to the local environment.
