In Southern Ontario our season for asphalt application runs from March through December.

Also known as blacktop, asphalt pavement, or hot mix pavement. Asphalt is an engineered mixture of aggregates.

There are two basic ingredients in hot mix asphalt. The first is the aggregates (crushed stone, gravel and sand) and the second is asphalt cement, the black liquid that holds the pavement together. Mix the two ingredients at temperatures of 150-175C and you get Hot Mix Asphalt.

Warm Mix Asphalt is an asphalt mix which uses an additive that allows the asphalt to be mixed and placed at temperatures ranging from 25 to 50 degrees below standard hot-mix temperatures.

Recently it has been gaining more attention because of benefits it has over traditional hot-mix. Using Warm Mix Asphalt means lowers emissions, a reduction in fuel consumption, and the potential to use more reclaimed asphalt pavement in the mix.


  • Asphalt or Concrete
  • Life Span
  • Installation

There have been numerous studies which have shown that asphalt pavements have a lower life cycle cost and the initial cost of asphalt pavement construction is usually less than concrete.

An increasingly important factor related to cost is construction time as more area can be covered with asphalt pavement than with concrete in the same period of time.

Asphalt repairs are also less expensive.

Your asphalt driveway or parking lot should last approximately 20 years if properly installed over a well compacted stone base.

Pavement life can vary greatly depending on base conditions, type and volume of traffic, and maintenance.

A milling machine is used to remove the existing surface asphalt and the area is cleaned of loose debris.

A prime coat of low viscosity asphalt is applied to the stone base in preparation for the asphalt pavement. This hardens the base and provides adhesion between it and the asphalt pavement.

Dump trucks are used to transport hot mix asphalt from the plant to the paving site and a heavy duty machine paver is used to pave a smooth pre-compacted mat. Then asphalt compactors/rollers then use their weight & vibration to increase the density the material.


  • Pavement Failure
  • Cracks
  • Seal Coating

Asphalt is a porous material, susceptible to oxidation from the sun and damage from liquids (water, gasoline, diesel fuel, oil, antifreeze, dissolved salt, etc) that penetrate beneath its surface.

Asphalt deteriorates when “fines” aggregates are worn away by weather and traffic. 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 cracks & failure.

Causes include inadequate thickness of the pavement section to support the loads travelling across the asphalt, lack of maintenance, and weak or unstable subgrade components.

Check for cracks and have them filled annually. Any crack, which is ¼-inch or wider in the pavement, will allow moisture to penetrate to the sub-base. The goal of a good pavement management plan should be to keep the moisture from entering the asphalt pavement.

Discourage the accumulation of dirt and seeds which allows small vegetation to get established. The tiny roots will widen cracks and help break down and undermine the surface.

Proper crack repair procedures can double the life of most asphalt pavements.

We recommend applying sealant every 2-3 years, depending on wear. This will help prevent deterioration of your pavement due to the sun’s rays, gasoline, traffic, and the weather elements. Seal coated asphalt is easier to clean and can withstand pressure washing. It’s also easier to remove snow because the surface is smooth. Sweeping is also more effective when the pavement is sealed.

Minimal recommended temperature at application and during the curing period is 13C. Higher temperature is better still. Traffic should be kept off for at least 18 hours, which is why large seal-coating jobs are done on weekends, overnight or in sections. It’s also important to do seal coating when no rain is expected for at least 2 days. Sprinklers should also be kept off.

Seal coating makes your pavement look new, protects it from oxidation and petroleum spills, extends its life, and protects your investment.
