Heavy Duty
Airports, ports and railways require paving solutions that can withstand extremely heavy loads and high pavement stress. These pavements are subject to sustained loads, often in channels such as loading bays which can lead to rutting.
Challenges
Extreme conditions involved in heavy-duty applications challenge paving solutions to their limits.
The extreme demands on heavy duty pavements present their own challenges. In airports, in particular, safety is of paramount importance and the surface must be able to withstand:
- Elevated weight loads;
- High and varying speeds;
- Severe weather conditions; and
- Increasing traffic frequency.
What’s more, it has become more important than ever to keep operation down-time to a minimum due to increases in airport traffic. Paving windows are becoming shorter.
Solutions
Shell Bitumen operate the highest standards of HSSE to ensure all deliveries are as safe as possible
We have developed technical and operational solutions to meet these challenges. For example, Shell Bitumen S-Grade binders are used in airfield applications being designed to deliver, compared to conventional bitumens:
- Improved asphalt performance through increased stiffness, better rutting resistance and improved adhesion performance;
- Improved workability of hot mix asphalt which makes it quicker to lay;
- Better asphalt compaction to help runways to be laid quicker;
- Extended laying window and transportation time and distance when asphalt manufactured at conventional temperatures; and
- Reduced energy costs and emissions with asphalt manufactured at lower temperatures.
We offer end-to-end solutions, from the development of bespoke mixes to meet individual specifications to the delivery of bitumen on site.
Solutions For...
Racetrack development
High performance polymer modified bitumen specifically developed for use in asphalt mixtures on racing circuits.
Downtime Reduction
Our quick-cooling bitumen solutions are formulated to allow you to re-surface in hours, helping to keep your roads and runways open for longer and keeping disruptions to a minimum.
Bridge Design
Bridge construction requires a pavement with the ability to cope with the demands of heavy vehicles and varying weather conditions. Mastic asphalt in combination with polymer-modified bitumen is an excellent material to meet these demands.
Low Temperature Mixing
Lowering asphalt mixing temperatures can reduce plant and machinery costs while lowering emissions of CO2, dust and fumes.
Risk marketing
Shell, as one of the largest hydrocarbon trading companies in the world, has the expertise to introduce pricing mechanisms to help customers to effectively manage their costs. In times of volatile energy prices, we strive to provide fixed price choices aligned to your commercial needs.
