Was out biking with my son in the trailer this evening, and happened to turn onto a street with freshly-laid asphalt pavement. Asphalt/tarmac/bitumen or whatever you like to call it. I immediately noticed my tires getting very sticky, so I moved over to an area that had not been paved yet. But since my tires were sticky, they picked every single little pebble and other debris. The tires actually sounded like they were flat as we rolled along, so I pulled over and checked. No problem, holding air just fine.
After we got past the fresh asphalt, the rest of the road was extremely rough from the old pavement being milled to accept new pavement. Very bumpy, very noisy (tires). I actually consider myself pretty lucky to have made it home without any flats.
When I got home I started going over the tires with a wire wheel in my drill to try to get the junk off that were stuck to them. Next time I will definitely avoid fresh asphalt if at all possible.
