Project Overview
Uxbridge Road was originally constructed as a concrete carriageway and had later been overlaid with asphalt. With the asphalt overlay failing, Platinum 3Sixty used a targeted Elastomac concrete road repair approach focused on the cracked and damaged areas of the underlying concrete.
The case study demonstrates a practical highway maintenance option for long residential concrete roads with multiple drop kerbs, where conventional channel planing and a further asphalt overlay can introduce additional issues around milling, carriageway levels, drainage and run-off.
The Problem: Failed Asphalt Overlay on a Concrete Road
The asphalt overlay on Uxbridge Road was failing over the original concrete carriageway. A standard channel-plane and overlay design would have required additional intervention into the concrete, which the project case study identifies as expensive and time-consuming on a long residential road with many drop kerbs.
Channel planing into the drop-kerb areas would also require the carriageway to be re-profiled, with allowances made for levels, drainage and run-off. If those falls were compromised, the case study identifies a risk of ponding.
The Repair Approach: Remove the Remaining Asphalt and Treat the Concrete
The approach was to plane off the remaining asphalt overlay and then repair the cracked and damaged areas of concrete with Elastomac. This concentrates repair activity on the defective areas of the original concrete carriageway rather than relying on another full asphalt overlay.
Targeted Concrete Repair
Elastomac was used on cracked and damaged concrete areas after the remaining asphalt overlay was removed.
Drop-Kerb Constraints
The approach avoids unnecessary channel planing into numerous drop-kerb interfaces along the residential road.
Levels & Drainage
The case study highlights the importance of protecting carriageway levels, falls, drainage and run-off.
Local Authority Use Case
The project provides a repeatable maintenance example relevant to London borough highway teams managing similar concrete roads.
Existing Defects & Elastomac Concrete Repairs
The photographs below show the failing asphalt overlay, the level constraints around a drop kerb and the targeted repair treatment applied to cracked and damaged areas of the concrete carriageway.
Why This Concrete Road Repair Case Study Matters
Uxbridge Road demonstrates an alternative maintenance approach for residential concrete roads where a failing asphalt overlay sits above the original slab construction. The case study focuses on reducing heavy concrete milling, protecting levels and drainage, and creating a scalable repair option for similar local authority highway environments.
Relevant to long residential concrete roads
Where multiple drop kerbs and drainage falls make conventional channel planing more complicated, targeted treatment of defective concrete areas can provide a different maintenance route for consideration.
