STONEmaster

Sustainable In-Situ Filter Drain Refurbishment

STONEmaster is a unique in-situ method for removing the sediment within roadside filter drains. The process returns the filter drain media to its optimum condition, improving road safety and pavement integrity by reducing flooding events and occasions of standing water on the carriageway.

Introduction

STONEmaster is a unique in-situ method for removing the sediment within roadside filter drains. The process returns the filter drain media to its optimum condition, improving road safety and pavement integrity by reducing flooding events and occasions of standing water on the carriageway.

The STONEmaster units are custom built, self-contained vehicles that enables us to meet all site safety requirements. They can be operated during the day or night in virtually all weather conditions and in most carriageway locations without the need for road closures.

The process is sustainable in that it recycles existing material and minimises the volume of additional material that has to be quarried and transported to site, thus significantly reducing the number of vehicle movements to and from site. Multiple units can work in the same TM closure for even greater savings and efficiencies.

Since being developed in 2002, Carnell’s 6 STONEmaster machines have operated in all the Highways England Areas and Scottish Operating Units, Welsh TRAs and most DBFO contracts. A number of Local Authorities have also utilised the innovative process.

Benefits

The advantages of STONEmaster align with the three Highways England imperatives:

Safety

People-plant interfaces on site reduced by a factor of 4.75 due to fewer lorry movements.

Reduced vehicle movements Improves air quality, contributing to improved health.

Stabilised verges minimises the risks of stone scatter and vehicle embedment.

Smarter surveying reduces need for trial excavations.

Customer Service

Less congestion through reducing lorry journeys by 79%

Fewer movements in and out of TM means road users feel safer.

Reduced flood risk helps customers feel safe on the network.

The faster process reduces network occupancy and provides customers with stress free journeys.

Delivery

StoneMaster generates £1million cost savings per 10,500m3 recycled.

Efficient process reduces volume of new filter stone and haulage costs.

CO2 emissions reduced by 7.1 tonnes for every km recycled.

Multiple units operating in tandem increases productivity.

Maintaining drainage prolongs pavement life demonstrating effective asset management.

Typical uses

  • Roadside filter drains in the verge and central reservation.
  • Reactive – Implemented where carriageway flooding has been observed.
  • Planned – In advance of visible issues where surveys show poor filter drain condition.

In the last 5 years THE Highways England NETWORK has SEEN:

265,477m3

of roadside filter drain recycled.

53,095

removed lorry movements from site.

1.4 million

transport miles removed from our roads. That’s the same distance as travelling round earth’s equator over 56 times.

79% reduction

in lorry journeys to and from construction sites.

300,000

litres of diesel fuel saved.

£25.1m

savings generated by the reduced volume of new filter stone reducing haulage costs.

7.1 tonnes

CO2 emissions saved for every km of filter drain we recycle with STONEmaster.

2,655 tonnes

of CO2 saved. Wwhich is the equivalent of saving the annual electricity consumption of 2,963 people in the UK.
