Resurfacing asphalt paving can often be the superior choice and can be a more cost-effective solution that will still see great long-term results and prolong the life of your asphalt.
Many factors including weather conditions, excessive flooding, traffic density, and intense direct sunlight can impact the lifespan of an asphalt surface. The most common side effects are cracking, buckling and slab shifts.
While wear and tear are completely normal and expected over the lifetime of your asphalt, and there are a few options available without the need to tear up and completely replace the existing surface.
Resurfacing is the middle ground for asphalt repair and it involves milling the existing surface to remove the top layer of asphalt and create grooves for the new asphalt to adhere to. The prepared surface is then swept and cleaned of all loose materials and a fresh layer of asphalt is applied, levelled and rolled, leaving the old asphalt underneath to provide support and thickness while the new layer offers an undamaged top surface.
We have found resurfacing to be more effective than patching, is less labour intensive, and will provide a better, longer-lasting result requiring less preparation and machinery to complete the job.
Depending on the damage and age of your asphalt, the team at C & D Asphalting will be able to assess your project and can help you decide whether resurfacing is a viable option before you consider a complete asphalt replacement of your roads, asphalt driveway, residential subdivision or carparks.
How long does it take for resurfaced asphalt to dry?
Resurfaced asphalt takes anywhere between 2 -6 hours to dry and around 48 -72 hours to be able to withstand regular foot and vehicular traffic. However, environmental factors such as extreme weather variations in temperature, humidity and rain will also affect drying time.
How long before you can drive on resurfaced asphalt?
Resurfaced asphalt can be driven on regularly and confidently after at least 48 hours of drying time has occurred. This needs to be adjusted for weather variations.
What is asphalt resurfacing?
Asphalt resurfacing is the process of removing and replacing the top layers of your existing asphalt. The new surface, which is usually between 2 -5cm thick, typically extends the lifespan of your driveway or carpark by 8-15 years.
Can asphalt be laid over concrete?
Technically yes, asphalt can be placed directly over concrete. However it is not recommended. We recommend you first remove the existing concrete before laying it on asphalt because pouring asphalt on a concrete surface decreases the surface durability.
A sub base of concrete is different from a sub base of asphalt which poses a serious threat to the pavement’s flexibility, stability, and strength. Asphalt needs a reliable base to withstand heavy loads or years of shifting; or else, you will end up with a cracked and deteriorated surface.To prevent cracks under normal weight loads, it needs a firm, stable, and flat base.
Can asphalt be recycled?
Yes! Asphalt recycling for paving has been around for a number of years, and the trend continues to develop and gain notoriety, particularly as people and companies are becoming more aware and conscientious of the impact industry has on the environment .
As early as 2011, it was estimated that:
Pete Davis (2016) described the move to recycling asphalt as the beginning of a trend that would establish asphalt as a leading sustainable material used in roads. This was reinforced by the National Asphalt Paving Association enthusiasm and encouragement. In addition to using materials from older roads to produce new roads, as well as used asphalt from roofs, the binder is also being recycled in large quantities. A process called the warm-mix procedure allows asphalt to be heated up at lower temperatures which saves energy and reduces emissions in road building and repairing. The environmental advantages as well as the cost savings to taxpayers encourage the development of sustainable methods of creating roads (Davis, P., 2016)
