Krusher, I'm just wondering why you would need a MSDS for crushed asphalt and concrete? My suggestion is if you get a gob full of asphalt then just pull out the MSDS for bitumen, either C170 or C320 it doesn't really matter. If you encounter a problem with dust from the crushed concrete then whip out the MSDS for Portlan Cement.
swaggy, That would be my thought too. I just wanted to make sure that I was covered if making an additional hazzard by crushing these products. Thanks.
