Granular Pavements: Should You Choose Foamed Bitumen Stabilisation?

9 February 2019 by Frank Lynch

If you have an old granular pavement on your commercial or industrial property, you should think about your rehabilitation options. Restoring the pavement will increase the strength and resilience of the structure, and the surface will perform better in relation to safety. One of the rehabilitation methods to consider is foamed bitumen stabilisation. This is treatment method involves applying foamed bitumen on the pavement to create a protective and reinforcing visco-elastic coating. Here are some of the reasons you should think about using the foamed bitumen stabilisation technique to improve your old pavements.

Compatibility With Materials

Foamed bitumen is an ideal rehabilitation medium for old pavements because it is compatible with most materials used in roadway construction. In simple terms, this repair substance has exceptional affinity to numerous granular construction materials. You can use it to restore natural gravels used in driveways and other commercial paths. It can also reinforce crushed rock aggregate surfaces. When choosing your foamed bitumen for your repair project, you can confirm the suitability of different mixes for your needs.  

Prolonged Performance

When rehabilitating a granular pavement, it is important to think about the durability of the structure after the repairs. The goal of restoring your old and worn out surface is to improve its performance and ensure that the pavement remains stable for a long while. Foamed bitumen stabilisation is the perfect technique if you want to extend the service life of your paving. Typically, when the bitumen cures, it will become a compact and elastic layer. This layer is strong and durable. Your pavement will also be less vulnerable to damage from moisture and temperature changes. In addition, the bitumen layer is quite flexible, so it is highly resistant to fatigue.

Economical Option for Repair

Finally, you should note that foamed bitumen stabilisation is an economical method for restoring or rehabilitating worn out pavements. Under ideal circumstances, an old and damaged pavement should be demolished and built from the foundation once again. Regrettably, this type of undertaking is expensive, time-consuming and inconvenient. If you decide to rebuild, you will need to pay for a lot of materials and labour, and your normal business operations will be compromised. On the other hand, if you choose simple patching compounds, you will need to plan for recurrent repairs. Patching compounds do not last long in a high traffic environment. Foamed bitumen is the ideal economical choice because it is not as intensive as rebuilding, and the restoration will last for a long time, minimising the need for constant repairs.
