Asphalt laying

Asphalt laying requires a lot of knowledge in the field, as there is an infinite number of varieties that affect the progress of the installation.

Plain paving laying is more than a job, it’s a real art. Why? Because to create a beautiful paving, you have to know how to choose the right materials and right color tones.

To do this, nothing better than to do business with a specialist who is used to working on such projects! By being attentive to your needs (as well as your budget), this one will be able to advise you adequately as for the various possible decorations.


Before asphalt is laid, it is necessary to:

  • Determine soil type for proper excavation planning;
  • Make an excavation of a depth of 30 to 40 cm (depending on the type of soil detected).

In the greater Montreal area, the soil is generally made of clay, sand, humus and limestone.

Clay soils
The clay soils found in and around Montreal consist of silt (the size of which lies between clay and sand) and clay. In other words, they are fine-grained soils (less than 0.075 mm). Therefore, this type of soil can be very soft… as it can be very hard, depending on its water content. This makes them either sensitive to frost or sensitive to drought, which causes their volume vary.

Sandy soils
These are the easiest soils to work because they are mostly made of sand. In addition to being very brittle and permeable, they are much less sensitive to temperature change.

Soft soils
With a good mass of organic materials, these soils, composed of an underlayer of limestone and a rocky bottom, are very fertile. Unfortunately, deep excavations in this type of soil can be very expensive.


When laying asphalt, the foundation is very important as it is the granular surface on which the even pavement will be laid. Generally, it made of rock of mg20 or 0-3/4 ʺ, unless the surface is soft. In such a case, the latter may contain a layer of mg65 or 0-2ʺ1/2If the paving to be installed is not asphalt, then a top coat of sand or stone screen must be made, in addition to installing a geotextile membrane.


These slopes prevent the accumulation of water that wreaks havoc on your paving.


Asphalt consists of bitumen, aggregate and fine sand. There are several types on the market, such as:

  • EB-20: bituminous asphalt where the rocks are sieved by 20 mm, it is used as a base layer;
  • EB-14: bituminous asphalt where the rocks are sieved to 14 mm, it is used as a base layer or intermediate layer;
  • EB-10s: bituminous mix where the rocks are sieved to 10 mm, it is used as a surface layer;
  • EB-10c: bituminous asphalt that is enriched and where the rocks are sieved by 10 mm, it is used as a surface or correction layer ;
  • EB-5: bituminous asphalt where the rocks are sieved to 5 mm, it is used for smooth corrections.

These types of asphalt are actually only a tiny fraction of the types available, the manufacturing formulas are extremely varied.


Since there are several types of asphalt, the paving varies depending on the type chosen. The paving can be carried out by a simple layer of asphalt whose thickness can go up to a maximum of 75 mm (3) and a minimum of 50 mm (2). You can also make a multi-layer paving or lay a base coat with a thick and resistant grain before continuing with a top coat.
