Abstract
The leachability of phenolic components from five kinds of asphalts was studied. The effects of leaching temperature, leaching time, NaCl and pH value on the leachability of phenolic components were analyzed.The potential hazard of phenolic components to water was evaluated through the leaching test because phenolic components are present in asphalt. The qualitative analysis of leachate was done by GC/MS. The results show that leaching temperature and leaching time almost do not affect the leachability of phenolic components, and phenol content does not exceed the limit of surface water standard at 100°C, in 30 min. But NaCl and pH value have much effect on the leachability compared with leaching temperature and time, and maximal phenol content exceeds the limit of surface water standard. The phenolic components having the potential hazard to water were almost alkyl substituted phenol belonging to volatile phenol.
