Why should I choose you to pave my driveway or parking lot?

We have been doing professional work since 1968. We manufacture the product, our equipment is top of the line, our expert staff is experienced and we have well trained asphalt pavement crews. We also pave highways, roads, streets, commercial properties, and residential driveways.

When can we drive on our new driveway?

From 2 to 6 hours after the asphalt resurfacing, depending upon the temperature of the day. If you can avoid turning the wheels of your vehicles when they are not moving that will help prevent scuffing.

Why are there scuff marks on new asphalt surfaces?

Scuffing of newly paved surfaces is inevitable given the nature of asphalt and our hot weather. Scuffs are just the sand being displaced and will wash away. After a month those scuff marks are rarely noticeable. Please note that asphalt requires 6 months to fully cure. Until then it is tender and you should be careful. Avoid tight turns, and turning the steering wheel when the vehicle is not moving. Avoid sudden stops if you can.

What are some of the causes of asphalt failure?

It is usually one of the following: inadequate thickness of the pavement section to support the loads that travel across the asphalt, lack of maintenance, and weak or unstable subgrade components.

Asphalt deteriorates when weather and traffic wear “fines” aggregates away. When the “fines” are worn away, there is nothing to bind the larger aggregates together and the surface begins to ravel. This weakens the pavement section and eventually allows water to penetrate the subgrade, which leads to pavement failure.

What causes fatigue cracks in pavement?

Fatigue cracks are direct result of excessive bending of the pavement surface. Asphalt will fail if subjected to repetitive or excessive bending as from vehicular traffic.

Why doesn’t asphalt stay that nice rich black colour?

The UV rays from the sun breakdown the carbon bonds in the asphalt oil thus causing the colour change from black to gray. It is that oil that binds everything in the asphalt together so when it is depleted erosion starts, some sand particles at first and then larger pebbles to stones then with water infiltration it is all downhill from there. This is oil also what keeps the asphalt flexible. So when the asphalt is gray and oxidized it is less flexible and more prone to cracking.

What causes potholes?

Possible causes of potholes include asphalt that was too thin, base failure under heavy loads or poor drainage that weakens the subgrade and base. Poor quality (segregation in the asphalt, poor compaction, or asphalt that was burnt or did not have enough oil mixed into it) may be a contributing factor.

What causes alligator cracks?

Usually, excessive deflection of the pavement causes alligator cracking. This is due to an unstable base or repeated traffic loads heavier than what the road was built to withstand. If this cracking is not addressed it will expand and cause more damage.

Why are these cracks in the asphalt along the edges?

Edge cracks are usually caused because there is not enough support next to the road or the base has washed out. You should avoid driving on the edge. If cracking is severe then it may have to be cut out and replaced.

When should a parking lot be patched?

Patching is a repair operation and can be done as often as needed, until a lot reaches the resurfacing stage (over 35% of the lot is alligator cracked). Damaged areas will get much worse after this stage so it is best to get them done before then. Schedule the repair work early.

When must a pavement be removed and replaced?

If the existing pavement system is completely unusable due to age, neglect or change of use, then there is no other option but to remove and replace it. If the asphalt lot or driveway is 60% cracked then it is more cost effective to remove it all and start over rather than continue patching.

Won’t all pavements have to be removed and replaced at some point?

No. If a pavement is consistently maintained it will never have to be completely replaced. With sufficient planning, a complete rehabilitation project will restore a pavement to as new condition or better.

How long does this remove and replace process take?

The entire pavement system must be removed with excavating equipment and hauled to a dump site. New base material is trucked to the site, graded and compacted prior to paving. So the size of the job and the distance from the quarry and asphalt plant play a large part in the timing.

When should a parking lot be resurfaced?

Resurfacing is ideal when the surface has become heavily oxidized but the base is still stable; usually when the asphalt is approximately 12 to 15 years old, provided it was paved and maintained properly (correct thickness for the traffic, proper compaction, correct type of asphalt, proper drainage, etc.)

How long should a newly resurfaced lot last?

Depends on deflection of the original pavement (prior to resurfacing), how many trucks use the pavement and the thickness of the new asphalt layer. But generally, you can expect at least 10 to 15 years before more serious maintenance is required.

How long before traffic is permitted on a newly resurfaced lot?

Rubber tire traffic will not damage the new asphalt but care should be taken to avoid sharp turns (especially power steering marks created by non-moving vehicles).

Why does the asphalt appear to have different textures in different areas?

Asphalt is comprised of roughly 95% varying sized aggregates and 5% black asphalt cement. It is natural to expect a variation in the surface texture of the asphalt between loads and in different areas of a paved surface.

What can I do about poor drainage in my driveway?

This is mostly a question of personal taste, but there are two primary differences. Asphalt is a flexible surface that has the ability to flex with use and slight movements of the base. Concrete relies on its own strength to absorb loads and bridge weaknesses in the sub-base. Concrete costs significantly more than an asphalt surface of comparable strength.

Can I put an asphalt surface over my old concrete driveway?

Yes. This can be done if the concrete has not deteriorated too much. But there is a caveat, reflective cracking is likely to occur as a result. Reflective cracking typically occurs along all the construction joints in the concrete or where the concrete has already cracked. This is due to expansion or contraction of the old concrete surface that then causes the asphalt above to crack as the concrete moves.
