Columbia Asphalt installed on an unstable surface can quickly lead to problems. There are three main options for the basic installation:
The more asphalt you work, the more leeway you have. For example, at 40 F, the crews only have 16 minutes to work on 1 1/2 inch thick asphalt. As the asphalt depth increases by 3 inches, the workability time also increases: 46 minutes. In general, for thin asphalt applications (about 1.5 cm), you should wait until temperatures are 21 ° C or higher. Between 50 and 60 F, you'll need to consult with your contractor. The hot mix is still functional during this period, but the time is limited.
Take into account the weather vagaries of our climate when choosing the quality of asphalt. The significant temperature variations that we experience cause considerable damage to asphalt work.
In addition, it will be good to tell the contractor if you own a recreational vehicle or a van. He will have to adapt the asphalt mixture in order to be more resistant to the weight of heavy vehicles.
A driveway paved with asphalt has several advantages:
It will cost you between $ 3 and $ 11 per square foot; the price varies depending on the quality of the asphalt used and the paving contractor.
The life of an asphalt paver can be up to 20 years, when the best conditions are met. We are talking about a professional paving contractor, a good quality of asphalt and an optimal asphalt laying technique.
The longevity of residential asphalt paving largely depends on the quality of the laying. Indeed, the major causes of deformation or tearing of an asphalt layer are the lack of compaction and a thin foundation. However, the maintenance of the asphalt pavement is also a determining factor in its longevity. That is to say, you will have to seal your driveway once in 10 years, at a minimum, in order to maintain its good condition.
We advise you to notify your asphalting contractor if you decide to have your driveway asphalt in order to sell your property. It might not be necessary to pay top dollar for laying asphalt , in this case.
The choice of the asphalt laying contractor is essential. In order not to have unpleasant surprises, you will have to choose it carefully.
Make sure the paving contractor has liability insurance. A visit to the website of the Office for Consumer Protection (OPC) will allow you to verify whether an entrepreneur has been the subject of complaints.
The following details should be included in the contract:
- date of start and end of the work;
- proof of insurance;
- technical details ;
- RBQ accreditation number.
You should know that a paving contractor cannot require you to make a down payment before work has started. However, you should agree on the payment terms and make sure it is on the contract.
Before redoing the asphalt driveway to your new home by a contractor, or acquiring some basic knowledge is imperative to make sure the job is well done. Know first that the lack of compaction and the insufficient thickness of the foundation are the two main causes of the deformation or tearing of a layer of asphalt. If it is a new driveway, it must first be excavated to make room for a layer of crushed stone of adequate thickness. A geotextile membrane will be placed under the granular backfill if the soil turns out to be very loamy (clayey). If you own a new home, it is best to wait 6 to 12 months before paving your driveway, to allow the soil to settle naturally. In the case of a repair of the entrance, a simple replacement of the asphalt layer can be considered if the contractor considers that the existing foundation is adequate. In both cases, foundation redone or foundation preserved, the duration of its warranty must be the same.
The weather conditions in our beautiful province can have a devastating effect on an asphalt driveway, hence the importance of including a slope with a minimum slope of 2%. This will allow water to drain to the street and minimize the risk of heaving or cracking. This important detail must be taken into account when excavating and maintained during backfilling.
If you have a van or recreational vehicle, notify the contractor before the start of the work: he will be able to provide materials accordingly. Some asphalt mixtures produce an asphalt that is more resistant to heavy-duty vehicles.
The asphalt layer should have an initial thickness of 6.35 to 7.6 cm (2.5 to 3 in) in order to reach a thickness of at least 5 cm (2 in) after being compacted. For optimum stability, the foundation should extend over the surface to be paved by about thirty centimeters (a dozen inches) on each side. Also note that the installation of side supports around the foundation is a good way to avoid possible cracks and that asphalting done in cold weather will be of inferior quality. It is therefore better to wait for the sunny days to return before starting work.
To avoid unpleasant surprises, choose your contractor diligently and make sure that the name and address of his business are written on the contract. The start and end dates of the work, as well as proof of the contractor's liability insurance and the technical details of the project to be carried out, should also be included. No contractor should require a down payment before work begins. To avoid the inconvenience that could cause unforeseen costs, visit the AsphaltColumbia SC website .
