Asphalt Paving FAQ

Asphalt is an engineered mixture of aggregate (stones and sand) with liquid asphalt cement (a petroleum product). Various sizes of aggregates are heated and then mixed in exact proportions with asphalt cement that has been liquefied at about 300°F.

Asphalt offers installation speed, usability and durability. It is also easy to maintain and the cost is not as expensive as using a paver or concrete.

Asphalt Milling is the process of removing a specific area on an asphalt surface to repair damage and carry out an overlay.

Because the process targets only the affected areas, repairs are completed in a time-efficient and cost-effective manner.

If your sub-base is still intact, Asphalt milling can be done to repair the damages on your asphalt parking lot, driveway, and other surfaces. Our estimator will help you determine the best way to go.

If paved and maintained properly, it can last 20 years or more.

Have a Burnaby Blacktop estimator determine if a topical fix can work for you. For example, a parking lot with longitudinal cracking and some areas of fatigue (alligator cracking) can be fixed topically. None of the repairs are full depth. But areas of upheaval, rutting, large ponding are usually indicative of problems involving the base, or sub-base.

One of our friendly estimators will investigate the situation and provide consultation.

Asphalt presents an economic advantage in both installation and repair, and retains flexibility.

Asphalt pavements can be prepared and overlaid with hot mix asphalt, resulting in a pristine product at significant savings to a re/re. (Removal & Replacement).
Your Burnaby Blacktop estimator will determine if a 1.5″ (40mm) overlay is a suitable application.

New construction paving can often be completed in rain, but in some cases, rain will cause delays in scheduling. Asphalt overlays are not done in the rain because the new asphalt will not properly adhere to the old asphalt.

It is important that you look into the materials that will be used, and the reputation (and credentials) of the contractor. You will want a contractor who understands your needs. Some clients have economic constraints. Burnaby Blacktop will work with you; though we may not always “say what you want to hear.”

At the end of the day, we are here to stay and our professional reputation is very important to us.

You should wait 1 week especially if constructed on hot summer days. This will reduce the likelihood of lasting dents. Surface marks may appear from dry turning (cars should be in motion while turning). Scuffs may appear in summer, especially on driveways where a Hot Mix Asphalt with a high sand content is used, but these marks will fade over time.

Potholes form by the intrusion of water below the asphalt, during freeze-thaw cycles, with vehicle traffic compromising the area.

Given that your asphalt driveway was properly paved, water penetration into its base is the main reason why asphalt fails.
Other usual suspects are a poorly constructed sub-base (or base), vegetative growth, or subpar materials.
The normal wear and tear resulting in the slow degradation of your product will be exacerbated by sunlight, weathering, chemicals, etc.

Regular maintenance will definitely prolong the lifespan of your asphalt. Seal coating, asphalt patching and crack filling are suggested ways to prevent costly repairs, or resurfacing.

We want to work with you maintaining your investment, no matter how small the task.

Yes. You can use ice melting products.

Fatigue cracking or “alligator” cracks are usually caused by water seeping through the cracks resulting in a weak base. Poor drainage will worsen this as erosion begins underneath.

Repairs should be carried out as soon as signs of damage become visible.
In fact, the underlying problem has been present already, long before it showed up, so it is best to call Burnaby Blacktop, ASAP!

Your residential applications will typically result in a mat laid at 2.5″, compacted to 2″ (50mm). Driveways tend to have a higher sand content resulting in a smooth finish showing less of the larger aggregate.
Commercial applications will incorporate larger aggregate and will typically be laid at 3.5″, compacted to 3″ (76mm).

Preparations (soil removal, existing asphalt/concrete recycling, sub-base and base) will involve machinery, and trucking.
Burnaby Blacktop crews prioritize ease of movement for the clients neighbors, as well as for the client. Leaving our worksites clean at each stage of construction. Impeding normal family life very little, leaving behind dramatic, and lasting changes often in one day.

Since the functionality, and appearance, of our parking lot is the first impression our place of business makes (as well as the last!) we recommend resurfacing as soon as necessary. And before degradation becomes so advanced as it requires large scale excavation.

Here can appear to be some desegregation of course materials from fine at the surface. This is normal. Finishers will minimize this, but it does not reflect on the products integrity. The product’s appearance will change over time, and minor textural variations will fade.

Your edges should have pleasing lines, or contours. Smooth transitions, with no scalloping or depressions.
The surface tension of the product is indicative of the density achieved in compaction.
