A96 Filter drain recycling: case study in climate resilience

14:35 - 15:00

Maintaining the road network in a safe and serviceable condition that is resilient to the impact of climate change, is vital to support a modern successful economy.

Increased surface water flooding is already recognised as a primary risk to the integrity of the network. The condition of roadside drainage is a key element in managing that risk. With value for money challenges as well, we need to imagineer smarter ways of taking care of our roads.

Recycling the filter media within roadside filter drains is one of these smart solutions.

Carnell’s STONEmaster solution recycles material in a single shift on site reducing the need to transport material off site, or quarry and bring new aggregate to site.

The benefits are wide ranging. Vastly reduced lorry movements, reduces the plant-people interface on site, reduces the volume of construction traffic, and reduces the number of lorry drivers required. Couple these benefits with the CO2 savings and cost savings, and the STONEmaster solution, that was used on the A96 earlier this year, is definitely a winner in making of network more resilient to the effects of climate change.
