I'm REALLY surprised nobody's mentioned the standard dickies work pants yet. I've had quite a few crashes where I've slid on the asphalt for a yard or two, and the pants rise up no worse for the wear.
My last one, I was wearing them over a pair of spandex shorts (longer ride). I bite it, slide on my side for a yard or two. When I get home, I have torn a hole in the spandex (tiny), a small patch of rash. Pants are still A-okay.
