Nov 20, 2019· As the title says, the ''90s tends to be remembered with disdain for the Dark Age, the loads of crappy comics that came out of it, and the industry almost dying. That was true, but like anything else, there''s some good stuff that came out of it. Here is where we''ll honor those stories, because if you make a good comic in an era where bad was the norm, shouldn''t that also be recognized?

The California Bearing Ratio (CBR) test is a simple strength test that compares the bearing capacity of a material with that of a wellgraded crushed stone (thus, a high quality crushed stone material should have a CBR ).It is primarily intended for, but not limited to, evaluating the strength of cohesive materials having maximum particle sizes less than 19 mm ( in.) (AASHTO, 2000 [1]).
