Around here they use fine gravel instead of sand, but either can be used. What they typically do is put down a thin layer of tar or asphalt and cover it with sand or gravel, whichever happens to be the less expensive option in your area.

It's a cheap way of resurfacing the road and making it last longer, so that they don't have to do a more expensive resurfacing quite as often.

I'm guessing in your case they are using it to smooth out the road surface after doing some work.
