CEMEX worked with AECOM design consultants to replace an asphalt surface layer which had failed after just 3 years of usage.
CEMEX’s roller compacted concrete was the perfect solution to overlay the whole yard and provide a tough durable surface suitable for heavy goods vehicles.
CEMEX were tasked with overlaying the existing yard with 200-220mm of RCC to provide the strength and durability required for a yard of this type. The resurfacing process was completed alongside a significant yard expansion. This added substantial fencing, drainage and associated groundworks into the already complex programme.
Another challenge was the 275kV overhead cables that had to remain live throughout the construction period.
CEMEX’s technical team worked with AECOM design consultants to design an overlay that would be capable of handling the proposed loads without failing.
CEMEX developed the programme to allow two thirds of the yard to remain open at all times, whilst still being able to undertake the works in a safe manner.
The operational team also programmed the various groundworks, fencing and drainage works to ensure that the programme was both accurate and achievable.
Finally, a new method of working was developed to allow for tipping away from the overhead cables to ensure overall safety of everyone involved in the contract.
CEMEX were able to programme the surfacing works to be completed in three equal stages, ensuring that at any stage a minimum of two-thirds of the depot were available to be trafficked. CEMPave was the preferred option due to its ability to be opened to heavy traffic within 48 hours.
The additional strength of CEMPave in comparison to asphalt has also removed the need for additional concrete plinths to take jockey wheels when parking HGV’s in specified areas.
Drainage works were saw cut out after CEMPave had been laid, and ACO drains replaced to ensure no issues with water/runoff in the surfacing layer or in the new groundworks.
CEMEX implemented a safe system of working to enable the delivery vehicles to tip away from the cables. With restricted height goalposts setup, tipping could take place away from the cables if required.
