HBM / CBGM

Reduce road construction depth by 50% and costs by 40% with Roadways HBM.

Roadways HBM is a hydraulically bound material made with 100% recycled aggregates. This cement-bound recycled aggregate material has been successfully applied across road, track and path projects.

See HBM in action:

• As an alternative to a constantly failing Type 1 lane for Lewes District Council: Peacehaven road resurfacing case study.
• As a winter maintenance solution for failing paths at Horam Park Golf Club: Horam Park Golf Club case study.
• As a sustainable, lower-risk, longer-lasting and cost-effective road sub-base for East Sussex County Council, allowing the road reconstruction depth to be reduced by half while achieving the same results: Croft Road, Crowborough case study.
• As part of a Green Apple Award-winning road scheme in Southampton, where roads were reconstructed three times deeper for the same budget: Southampton Road Recycling Programme and International Green Apple Environmental Award.
• To reduce the construction depth of the A27 Arundel S278 works by half: A27 Arundel S278 HBM case study.

Best used for:

• Private roads and shared residential driveways
• Farm tracks, agricultural access roads and rural estate paths
• Commercial yards and industrial storage areas
• Hardstandings and temporary construction site access
• Car parks and structural aggregate sub-bases
