CRCP Repairs, A30 Devon

LMS Highways install CRCP Repairs to busy A30 Devon

Working on behalf of Balfour Beatty, LMS Highways spent three weekend providing Continuously Reinforced Concrete Pavement Repairs to the A30 in Devon. This stretch of road is made up of high speed dual carriageway, high speed single carriageway and urban areas, due to this, our repair work was completed under full night time road closures, ensuring the safety of everyone on site and to reduce disruption for commuters.

The A30 is constructed using CRCP, continuously reinforced concrete pavement is constructed with steel reinforcing bars placed within the concrete, continuously along the entire length of the pavement. The result is a continuous, smooth-riding surface capable of withstanding the heaviest traffic loads and the most adverse weather conditions. Often proving a popular choice for highly trafficked areas due to being extremely heavy duty and offering a service life of around 20-40 years, or even longer with the proper maintenance.

Repairing CRCP requires precision and accuracy, after removing the damaged sections of concrete, new steel starter bars are installed at 150mm centres just slightly offset from where the existing ones are. The dowel bars are then resined into place and steel mesh/ reinforcing bars are attached at both ends running continuously along the length of the bay, ensuring the continuous reinforcement isn’t broken or disrupted.

Project outcomes:

• 141 M3 Concrete Installed
• 5.7 Tonnes of Steel
• 373 Linear Meters of Joint Sealing
