Asphalt may be just the material which you need for constructing a new driveway or maintaining the old one if you have been limping along for years with a cracked, crumbling driveway.
This is not the same as asphalt driveway sealant which is a coating used to refresh the existing asphalt and this is something to note for asphalt repair in Sydney.
Along with its concrete counterpart and offering reasonable durability at the middle of the road price, asphalt is one of the most popular driveway materials.
As asphalt is a more specialized product than concrete, the materials which you shop for to do a repair will be less familiar as repairing asphalt driveways and fixing concrete both are handled well be the asphalt contractors in Sydney.
What is included in asphalt repairs in Sydney?
To what the road crews are laying on the roads, asphalt driveway materials are much similar to them. It is an aggregate of stone and sand along with a slurry of asphalt, a tar-like material made from petroleum and is also called hot mix or hot mix asphalt.
To liquefy asphalt it required 300 degrees F. Before the mix solidifies, the asphalt contractors have to work with it fast.
It is not a driveway sealant or a crack sealant when it comes to this hot mix. For repairing asphalt driveways, these are merely surface treatments for repairing or renewing.
Prior to the application and cure differently of hot mix, some of the asphalt patching materials are similar to the hot mix and are not heated prior. Installing new asphalt paving is not a do-it-yourself job while the homeowners can repair or reseal and asphalt driveway.
Asphalt vs. concrete driveway
Making the asphalt a desirable option for a new driveway there are several factors:
- Flexible: It is less prone to cracking as asphalt is more flexible than concrete.
- Less expensive: It is typically cheaper than concrete when it comes to asphalt paving.
- Hardier in winters: By the rock salt and the ice melt, it is less prone to damages.
- Faster-setting: As it hardens by cooling rather than curing, asphalt sets faster than the concrete.
- DIY fixes: You can do it yourself with driveway sealant when you eventually need to resurface your asphalt. By the do-it-yourselfer, concrete cannot be resurfaced.
Asphalt has some drawbacks when compared to concrete on the flip side:
- Lowering the resale value: Concrete typically has a higher perceived value by home buyers compared to asphalt.
- Uneven edges: The edges of an asphalt driveway tend to be less than perfect unless you install concrete edging to hold in the hot mix.
- Plants: Some plants can force up through the asphalt while not a common occurrence. One such plant is bamboo.
Options available for the asphalt paving base
It is only as good as its base when it comes to asphalt driveways. It can develop problems quickly for asphalt which is installed on an unstable base. For the base installation, there are three options.
Over existing driveway installing paving: Hot mix asphalt can be laid right on top of your driveway if your existing driveway is not in a good condition. Make sure that the fences, garage floors, and other structures will not be affected by the higher level of the new surface as one consideration is the height.
Removing the old driveway and paving on soil: You may not even have existing driveways or when the existing driveway is completely removed and 4 to 6 inches of hot mix paving is laid directly on the soil.
Removing the old driveway and paving on aggregate base: This is the most preferred method. Some of the hot mix asphalt is replaced by an aggregate stone base. 6 to 8 inches of aggregates go under 3 inches of asphalt typically.
Asphalt paving installation by the asphalt companies in Sydney
An average driveway may begin looking like a finished product is as little as 40 minutes once the base preparation is complete. More time will be required to compact the asphalt, however.
The asphalt needs to harden after this. You will be able to drive on the driveway within two or three days and it can take 30 days or more for asphalt to fully cure under most conditions.
You can use the driveway as normal but you should be careful to avoid the scuffing the surface with car tires and other common causes of the damage during that time which are done by the asphalt companies in Sydney.
The best time to lay asphalt
On warmer temperatures for the workable conditions, hot mix asphalt paving is dependent on this. The best seasons for installing an asphalt driveway are the springs and summer.
The less time asphalt paving crews have to work with the asphalt with the colder air temperature. To smooth the asphalt across your driveway, crews need time.
Your driveway may be bumpy, uneven, or irregular or the project may not even get finished if they do not have enough time. Winter is not a good time to install driveway asphalt while it depends on where you live.
Another factor is the thickness of the paving. The more leeway you have with the more asphalt which you are dealing with. At 40 f crews have only 16 minutes to work with 1 ½ inch thick asphalt for instance.
It takes around 46 minutes as the depth of asphalt grows to 3 inches. For the thinner applications of the asphalt, you will want to wait until the temperatures are at 70 G generally.
You will need to consult with your contractor between 50 to 60 F. The time would be a limit through a hot-mix is still workable during this time frame.
