Asphalt is produced at Carrington using hard rock aggregates sourced from Boral's Seaham Quarry north of Raymond Terrace, and fine sand from the organisation's Stockton Quarry at Fullerton Cove, in combination with bitumen and other components.
The plant is also capable of using Recycled Asphalt Product (RAP) in production at a rate of around 30 percent of input material volume. The sies production capacity is around 180 tonnes of asphalt per hour (up to 150 000 tonnes per year).
Projects have included surfacing of the V8 Supercars circuit in the Newcastle CBD when it was created in 2017 ahead of the first racing. In more recent years, Carrington Asphalt's role has expanded to take in works as far away as the Central Coast, Upper Hunter Valley and Mid North Coast on critical routes such as the Pacific and New England Highways.
Boral Asphalt Carrington provides employment for six on-site staff, with up to 15 heavy vehicle drivers also working from the site in transport of both raw materials for manufacturing and final products.
An environmental management system (EMS) is in place at Boral Asphalt Carrington which provides details of controls implemented to address relevant environmental aspects and potential effects of the site.
The EMS incorporates the arrangements for water management, noise control, air quality control, hazardous materials management and waste management.
Recycled Asphalt Product (RAP)
With the constant need to improve sustainability and conserve our natural resources, Boral Asphalt's product range increasingly makes use of recycled asphalt product (RAP).
RAP is produced when the still usable parts of a former road surface (profilings) are crushed and screened, creating a reuasable material which can be substituted into new asphalt production.
Making use of RAP means a reduced need for the supply of raw materials needed for manufacturing, such as hard rock aggregates and fine/excavated sands.
The quality of the RAP and the capabilities of each individual plant determine how much can be used in production.
Presently Boral Asphalt Carrington can use up to 30 percent of RAP in making its asphalt - this is a figure which the business is working hard to increase.
NSW Protection of the Environment Legislation Amendment Act 2011
Boral Asphalt Carrington has reporting obligations under the NSW Protection of the Environment Legislation Amendment Act 2011.
This Act applies to sites which operate under an Environmental Protection Licence (EPL) and requires the provision of public access to pollution reporting data. You can access this data here.
Boral Asphalt Carrington is operated to a development consent (DA2012/665) granted by the City of Newcastle Council for the upgrade of the site undertaken during 2012-14.
The consent sets out the operating, environmental and reporting conditions the plant must comply with throughout its operational life.
Two modifications to this consent have been subsequently sought and approved.
