Can you repair CRCP? In short, yes we can.
Let’s start with what is CRCP? Continuously Reinforced Concrete Pavement is constructed with steel reinforcing bars placed longitudinally within the concrete along the entire length of the pavement without any transverse joints. This often leads to an assumption that CRCP sections cannot be repaired or refurbished.
Back to the question, can you repair CRCP? Yes, when repairing or replacing CRCP we remove a square 4m patch and drill new steel starter bars in 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 and run continuously along the length of the bay, this ensures we aren’t disrupting or breaking the continuous reinforcement. This results in a smooth-riding surface with no transverse joints which is capable of withstanding the heaviest traffic loads and the most adverse weather conditions.
LMS Highways has been delivering CRCP repairs for many years – most recently working on the A449 in Wales, click here to read about the project.
