In one of our longest ever continuous concrete pours, Cymru Quarry Group built the foundations for Pembroke Refinery in Milford Haven, a massive £127 million investment by Valero to build a combined heat and power (CHP) cogeneration plant.
We delivered a total of 483m³ of concrete coordinating deliveries from two plants using 16 ready-mix trucks each doing four trips, but it all went without a hitch.
We have the capability of being able to do even more than that so do get in touch about your projects.
Asphalt is a mixture of aggregates, binders (bitumen) and fillers, and is commonly used for roads, pavements, bicycle lanes and sports areas. At Cymru Quarry Group, the aggregates we use come from our own quarries and are a mixture of crushed stone, gravel and sand.
Bitumen is used as a binder to hold all the materials together. Bitumen is a sticky, black, highly viscous liquid or semi-solid form of petroleum.
Asphalt is primarily used for road construction, but it also has various other applications, including car parks, pavements, driveways, runways, and recreational surfaces like tennis courts and playgrounds, It’s incredibly versatile.
Asphalt is used in 96% of all roads in the UK. Different types of asphalt are used to construct a road and can be broken down as follows:
- The surface course, the uppermost layer, spans approximately 25-50mm in thickness. This layer serves as a seamless, skid-resistant, and water-resistant surface, ensuring safe and smooth travel.
- Next in line is the binder course, boasting a thickness of around 50-90mm. This sturdy layer bears the weight of traffic, effectively distributing it across the road’s surface and into the base course. Additionally, it functions as a levelling agent, ensuring the pavement’s uniformity.
- Finally, we have the base course, resting on top of a sub-base, offering essential load-bearing support for the road. As you go down through the layers from the surface to the base, the aggregate size typically increases while the bitumen content decreases, contributing to the road’s strength and stability.
