If you are about to embark on one of the best investments you have ever made, the asphalt paving of your Ontario residential driveway, you may process information.
The C. Aurora team have put together an overview for you of what to expect, during the project, from demolition to delightful driveway.
If we are not working on a virgin site then we start by removing what is existing. Demolition is done using heavy machinery, including small bobcats and forklifts.
For removal of demolished materials, we use front loaders and large dump trucks. Debris is removed once the truck is full.
Old asphalt and concrete can be recycled which is wonderful for our planet. Asphalt paving is both green and environmentally friendly.
Grading and Sloping
The land is surveyed and the correct levels are ascertain to ensure good water drainage so you don’t have pooling or water penetrating your paving.
Laser levels, GPS and automatic motor graders made sure the sub-surface is perfectly graded.
Water can cause major damage such as potholes, cracks, and heaving so getting the drainage right is important.
Sub Base Preparation
As with most things in life, it’s what is underneath that is important. The sub base provides the critically important stable surface on which the flexible asphalt is laid. This flexibility on stable base gives a strength that is greater than the sum of its part.
The factors of base thickness, base stability, and compaction are critical to the long term success of the product. It is important that time is spent on this stage.
The sub base is now fully graded and compacted as hard as rock. The proof roll checks the validity of this conclusion. A dump truck, loaded with 72,000 pounds, is driven row by row over the entire surface.
If a flexing of more than an inch is measured then repair and additional compacting is needed. Undercutting is a method that repairs soft spots. The team digs 2 to 3 feet below the surface and remove any problematic clay or soft soil, replacing it with stronger aggregate material.
Geo-grid is another options whereby the dig is only 16 inches down. A grid is laid down to bridge base materials together. This is a solid support structure for new asphalt and is more cost-effective than traditional undercutting.
Plowing is another option. After digging down 2 to 3 feet, the soft clay/soil, is mixed with strong aggregate to improve the strength of the area.
A binder layer of large aggregate plus oil is laid. This amplifies the the strength of asphalt surfaces.
New Asphalt Surface
Surface asphalt is dense mixture of small aggregate, sand, and oil. This mixture is jet-black asphalt. It is laid, ready to be rolled to give you that silent, smooth ride.
Most asphalt surfaces need a transition from one surface to another. Areas where asphalt meets concrete, another asphalt or other is called a butt joint. These joints require special attention.
The entire surface is now rolled smoothed and compacted using a roller truck. This ensures there are no small bumps or stones poking through the smooth new surface. Perfect for skateboarding!
