One very important consideration for a residential driveway is the pavement width. For a single automobile, the width is 8 feet or 10 feet (for greater flexibility). When pedestrians and automobiles will use the driveway, it is best to have a minimum of 12 feet.
Two-car driveways need a pavement width of 20 feet for free and unobstructed door openings on both sides.
When the driveway meets the street, it is preferable to have 8 feet or minimum of 6 feet.
You should know that reputable contractors offer a warranty for the workmanship, usually 2 years, in case a problem with the construction arises.
What is the recommended pavement thickness for an asphalt driveway?
A smooth pavement doesn’t always mean it is great. The quality of your asphalt driveway is measured by the thickness and compaction. The minimum recommended compacted thickness is 2 inches (50mm) of hot mix asphalt. Generally, each asphalt layer is about ¾ of the loose hot asphalt mix.
For durability, a driveway should have 2-inch base course and 1.5 inches of surface course.
Paving contractors must always indicate the compacted thickness in an estimate or quote for clarity.
Options to repair asphalt pavements
Asphalt pavements are popular in Montreal because they are easier to repair than concrete.
Some of the options to repair an asphalt pavement include:
Hot sealant is applied to fill cracks in the pavement to stop further damage. The sealant adheres to the asphalt to keep water from penetrating the cracks and further weakening it.
Some homeowners delay filling the cracks and they get bigger over time. A small crack will quickly become a pothole and weaken the entire surface.
Seal coating the asphalt pavement will prevent oil, water, fuel, and traffic from causing more damage. This is an easy process and it should be done every 3 or 5 years to protect the asphalt, preferably in the warm months.
Seal coating is applied to new pavements to make them last longer. If you need a way to improve your pavement’s appearance, seal coating is a simple way to do it. It can also make long term maintenance of your asphalt pavement cheaper.
Milling involves the removal of the asphalt’s top later without compromising its sub-base. This is a great option if the sub-base is good and only the upper layer of the asphalt needs to be repaired.
This method costs only a fraction of a complete reconstruction because only the upper portion is replaced and can be completed in just a short time.
Patching involves filling in the potholes of your pavement. It is usually done by removing the damaged asphalt, cleaning potholes and removing debris, repairing the foundation, using hot or cold mix asphalt to fill in the holes, and them tamping down the excess filling.
