Main roads and highways usually extend from one state or province to another and also serve as the main routes for the commercial transportation of goods over long distances.
With the heavy traffic demands, a pavement solution which is durable and quick to lay is essential.
They are often high-speed networks - effective paving solutions are essential in helping to keep commercial vehicles and car drivers safe on the road.
Safety is paramount in the design and laying of main roads, with features such as skid resistance, water spray management, and luminescence key in helping reduce the potential for high-speed accidents.
Main roads come with their own set of demands and challenges, including:
- Increased speeds and traffic intensity, as well as elevated vehicle weights;
- Severe climate conditions leading to potential for cracking and high-speed skidding;
- Air and noise pollution;
- Maintenance and repair work during peak times; and
- Cost-efficiency in budget-restricted times.
Our solutions are designed to withstand the demands of high volume inter-city road networks and highways. With heavy traffic demands, a pavement solution which is durable and quick to lay – thus reducing maintenance downtime – is essential to keeping the traffic flow moving and keeping the roads open.
The volume and intensity of traffic on main roads creates the ideal opportunities to fully utilise Shell Bitumen’s technical innovations such as premium binders for porous asphalt to help increase road safety and efficiency.
With improved workability to reduce the paving window and increased durability, the lifecycle cost of main roads is considerably reduced. With higher adhesion rates, there can be a reduced risk of water ingress and associated maintenance costs.
Speed is a key factor – not only the speed of the traffic on the road but responsiveness to our customers’ needs; a reliable supply of bitumen from a sustainable source, delivered on time, using a first class delivery network.
This all helps our main roads remain open, minimising disruption to road users.
High performance bitumens designed to maximize resistance to permanent deformation and reduce fatigue of asphalt mixtures that are used in the most demanding locations.
Recycling road pavements involves removing and re-using the surface course in a new asphalt mixture to repair or resurface an existing road, reducing the amount of new aggregate required.
