Asphalt paving in Kanata

Commercial paving in Kanata splits into two kinds of property, and they behave differently. The retail corridor along Terry Fox Drive and Hazeldean Road carries large parking fields that fill and empty every day. The office and light industrial lots behind them carry steady, heavier traffic from delivery vehicles and, in the industrial pockets, from trucks that turn on the same corner every week.

The retail side

A large retail field has one advantage and one problem. The advantage is space: there is room for a paver to make a long, straight run and for a roller to work behind it without crowding the traffic that is still using the lot. The problem is the entrances and the fire route, which cannot be interrupted without a plan.

Work on these lots is normally sequenced by row, starting away from the busiest entrance and working in, with access maintained from at least one side at all times. Because the fields are wide, the fresh surface usually has time to cool before the section is reopened, which removes the overnight closure that tighter lots need.

Office and industrial lots

Office campus lots in Kanata are often nearly empty in the evening, which makes after hours the most efficient window. Light industrial properties are the opposite: the yard is busy all day, and the docking area is the part that takes the load. On those sites the paving plan is built around the dock, the turning radius for a trailer, and the fact that a loaded truck turning slowly does more damage to a weak surface than anything else on the property.

Where these lots fail

Wheel paths. A retail field sees the same traffic pattern all day, and the drive lane in front of the storefronts takes braking, turning and idling loads. When water gets into the surface there, freeze-thaw opens it from underneath and the alligator cracking appears in exactly the wheel path it started in. That pattern is a base problem, and it is the point where sealcoat stops being the answer.

The other repeat failure is at the catch basins on the low side of the lot. A basin that has settled below the asphalt creates a ring of standing water, the apron cracks, and the asphalt around the frame starts breaking up within a winter or two.

Access and equipment

Kanata lots generally allow full sized equipment, and that changes the economics of the work. A paver can lay a wide mat in fewer passes, and a tandem roller can follow it closely enough to compact the mix while it is still in the right temperature range. Where a lot has a narrow rear service lane or a tight garbage enclosure, that section is handled separately with smaller equipment.

Paving season

The window is the warmer months, the same as the rest of the city. For retail fields, the practical approach is to schedule the work outside peak shopping periods and to keep the entrance nearest the anchor tenant open for the whole program. For office lots, the calendar is easier: a weekend or a series of evenings will often cover the whole scope without affecting anyone.

Striping is redone at the end of the work, and it is worth reviewing the layout at the same time. Retail fields are often striped for a tenant mix that has changed, and a revised stall pattern can recover spaces that were effectively lost.
