Effect of temperature and humidity on oxidation of air-blown asphalts
Changes in infrared absorption in carbonyl band caused by carbon arc exposure of roofing asphalts; both temperature and humidity affected rate of asphalt oxidation, former being more critical parameter; sensitivity of asphalts varied with asphalt source and durability; relative order of oxidation stability of asphalts exposed outdoors was, in general, same as that for carbon arc exposure; formation and subsequent decomposition of asphalt-oxygen-water complex is proposed as possible mechanism.
