Drainasphalt lends a helping hand to The Royal Oldham Hospital

Aggregate Industries have supplied their Drainasphalt for a brand new carpark at The Royal Oldham Hospital in Manchester.

Drainasphalt is a permeable asphalt that allows water to pass freely through the underlying structure and is used as an asphalt porous surface and binder course component in a Sustainable Urban Drainage System (SUDS) pavement.

This material also reduces surface water spray and headlight glare in wet weather, and its inverted texture allows for high capacity acoustic absorption.

Aggregate Industries’ technical team worked alongside Bethell Construction to install the 100mm layer of 63-10mm aggregate over an impervious membrane, with a 50mm layer of Type-3 sub-base on top.

Water will now drain into an attenuation tank with an underground soakaway, while a drainage channel running along the middle of the car park was also incorporated into the design.

The surface of the car park was laid in layers of asphalt approximately 90mm of 20mm Drainasphalt Binder Course and 40mm of 10mm Drainasphalt Surface Course.

A 20mm Dense Binder Course and 6mm Dense Surface Course were also used for the footpaths, and 30/14 Hot Rolled Asphalt was used for the new access road.
