Question re: asphalt vs. concrete

[nickbeaulieu]

Hey all,

I was wondering if anyone could tell me what the deciding factor is in using asphalt vs concrete for sidewalks and curbs.

There are a few road projects going on on the route to work for me. One is near my home. They're building bus stop pads, and they're using asphalt for them. There's one spot that has a pad on each side of the road, and one side has a concrete curb and the other has an asphalt curb.

The other spot they're doing work is the road connecting the south fraser perimeter road and king george near the pattullo bridge. The sidewalks are all concrete, but they've also got bike lanes, and these are asphalt.

So aside from cost, and ease of installation is there a reason to use asphalt over concrete?
