Any exterior of an Australian household is supported by a well-laid driveway. Time and the hot sun, however, have their way whether you are in a classic Bitumen Driveway or modern asphalt driveways. The choice between choosing a simple resurface or a complete replacement is very important to your budget and property value.
Knowledge of the Surface Condition
Structural integrity of your pavement is important before committing to a contractor. The other method that is an excellent way of refreshing the look is resurfacing (overlays), but this can only work in cases where the foundation is solid.
5 Signs Your Bitumen Driveway Requires a Resurface or a Complete Replacement
1.The Fifth Man was Faded Colour and Oxidation
You see your driveway is no longer a deep charcoal, but a light grey, then that is because it is being oxidized by the UV rays. A Bitumen Driveway resurface is ideal in this case where there are no deep cracks. It replenishes the rich colour and it also provides a waterproof coating.
- Hairline Cracking (The “Spiderweb” Effect)
Asphalt driveways have small and shallow cracks. When such cracks are less than 5mm wide, filling them with resurfacing will help to seal water from leaking into the sub-base. Nevertheless, when the cracks look like alligator skin scales, the base has broken, and it needs to be replaced completely.
- Small Potholes and Pitting
Even a small number of potholes can be repaired and followed by the application of new bitumen. Resurfacing is a cost-effective solution in case the damage is localised. When the surface is crumbling over a third of the surface, then you have probably a complete excavation.
- Standing Water and Drainage Problems
Do you have water standing in the center of your driveway when it rains? This normally signifies that the sub-grade has moved or that it has not been levelled properly. Although minor dips can be repaired through resurfacing, serious drainage issues normally require a complete replacement to re-grade the land.
- Pavement Age
The average life of most asphalt driveways in Australia is 15 to 25 years. When your driveway is nearing the 20-year mark and you notice it is becoming structurally tired, a resurface is simply a Band-Aid. In this case, a complete replacement is the more intelligent long-term investment.
Summary
The decision of whether to perform a total replacement or a resurface is determined by the condition of the foundation. In case the problems are aesthetic in nature or include some minor cracking, a resurface will cost you thousands. Nevertheless, when the “bones” of your driveway are broken, there is no other solution except to start your new life and guarantee that your home will not be closed and not interesting to look at in the following years.
