The honest answer is a range, and the range is wide because the thing that decides it is not the asphalt. It is what was built under the asphalt and whether water has been allowed to reach it.
What actually decides how long Edmonton asphalt lasts
Two surfaces laid the same week by the same crew can be years apart at the end of their lives. The difference is almost always underneath: how deep the base is, how well it was compacted, and whether the ground under that was sound.
Water is the mechanism that turns a weakness into a failure. A surface that sheds water keeps its base dry and intact. One that holds water in a low spot lets it work into the base, and once that softens, the asphalt above has nothing to sit on.
Traffic matters but less than people expect on a driveway. Cars are light. What ages a residential surface is sunlight and temperature cycling, which is why coating helps, sealing cracks helps more, and how it drains matters most of all.

Reading its age
How to judge where your Edmonton surface is in its life
Look at the cracking pattern
Separate lines are normal ageing. Cracks that have joined into connected shapes mean the base is moving, and that is a different stage entirely.
Check whether it drains
Walk it after rain. Water standing anywhere is the single strongest predictor that the surface will fail early in that spot.
Feel the texture
A surface losing its stone to the touch has oxidised through. That is near the end of the surface course, though not necessarily of the build underneath.
Find out what is under it
A thin build on soft ground was always going to be short-lived. Knowing that changes whether you maintain it or plan to replace it.
Buying more years
How to add years to Edmonton asphalt
Crack sealing is the single most effective thing available, and it is the least expensive item on any maintenance list. Every crack left open is a route for water into the base, which is the failure that ends a surface.
Fixing a drainage fault returns more than coating ever will. A low spot that holds water will fail no matter how often the surface is sealed, because the damage is happening from below rather than above.
Coating is worth doing on a sensible interval and is widely oversold. It slows oxidation and evens the colour; it does not add strength. A planned cycle covers all three, water that will not leave is the item to fix first, and the end-of-life signs are worth knowing before you spend.

What affects Edmonton asphalt life
The items that move the number in either direction.
Because the base decides it and bases vary enormously. Two surfaces laid the same week on different ground will not reach the same age, whatever the asphalt above them is like.
It slows surface oxidation, which helps. It does not add strength and it does not stop water reaching the base, so it is useful rather than decisive.
Water that cannot leave. A low spot that ponds will fail in that spot regardless of how well the rest was built or how often the surface has been coated.
Cars are light enough that it rarely matters. Delivery trucks and skips do, because the load concentrates, and they are worth keeping off a residential surface where possible.
Often yes. A faded surface with a sound base and separate cracks has years left in it, and replacing it would spend a large sum to buy very little.
Not with certainty, but the symptoms are reliable. A surface that has settled, or whose edges are breaking away along their length, is telling you the trouble is underneath rather than on top of it.
