Bitumen Spray Sealing is the most common road surface used in Australia. It is a flexible pavement product that can also be used as a surface treatment in numerous situations including:• Rural driveways
• Rural roads and properties
• Urban & residential streets
• Car parks
• BMX tracks
A bitumen seal is formed by the spraying of a bitumen binder and covering with a layer of aggregate. A seal may contain more than one application of binder and / or aggregate.
A pavement is resealed as part of a periodic maintenance program when the condition of the existing surface requires the application of new bitumen binder and aggregate to restore one or more of the functions of the original seal. This provides a new surface on which vehicles run and re-water proofs the pavement.
Is a combination of a spray coat of hot bitumen binder to waterproof the area, followed by an even spread of aggregates. The final finish of a spray seal is from fine to coarse – depending on aggregate size selected.
There are many different ways to carry out a btumen seal with a multitude of bitumen types, spray rates, aggregate sizes and so on. A seal must be designed for your specific site considerign the type of base, traffic, life expectancy just to name a few key points.
A bitumen spray seal can be done as either single coat seal ( single/ single) or a Two coat seal ( double / double). A spray seal finish is only as good as the prepared base, as it will follow all depressions in the unsealed pavement. A tight, sound surface, formed to the desired shape is required prior to applying the seal as it will perfectly mirror any imperfection in the base preparation.
In some situations where the pavement is not to standard and there is a risk of damage to the prepared pavement surface a dry matt of aggregate followed by a heavy application for bitumen and a top coat of aggregate is applied to achieve the same result as a two coat, without damage to the underlying surface. Dry matt should be used in low stress areas only.
A bitumen spray seal treatment is specifically designed following the Austroads Seal Design Method, which, amongst other parameters, is based on seal aggregate size, design traffic loads and volumes, and the underlying surface texture. The lower the traffic volume and the greater the aggregate size, the greater the bitumen application rate required to hold the aggregate.
Advantages of using Bitumen Spray Sealing
If at a later date you need a pipe replacing or you wish to add on your existing area, we can match the area with the same product, without unsightly seams or marks (unlike concrete which shows the repair).

Cracks in pavements allows moisture to penetrate the surface which causes permanent material failure. Failure to seal cracks results in further cracking, potholes and eventually a major pavement breakdown, leading to unnecessary expensive repairs.
Austek Asphalt Services has the equipment and expertise to cut, lift and replace sections of road, carpark, driveways etc with ease by our professional qualified staff. We are happy to take on all jobs because to use no job is too big or too small.
This is a more cost effective process to resurfacing as the original asphalt is kept intact and doesn't need to be cut and lifted out. This overlay process however can only be achieved if the original surface is reasonably intact to get the best life possible out of an asphalt overlay.Read more...
To relay an asphalt surface, the old layer first needs to be removed. This is probably the most labour intensive task of the entire operation. Specialist machinery can help however, and it’s common to have one team dismantling the old surface, while a second team begins laying the new road behind. This technique allows entire roads to be resurfaced very quickly.
We work with clients to develop and provide specific road maintenance strategies and services, tailored to individual road networks and their operating environments. Our experienced staff are on call to quickly asses and give a detailed report to what may be required to help maintain or what repairs may be required to our Australian road network.Read more...
