ABSTRACT
The National Asphalt Pavement Association (NAPA) has received many, many calls over the last year or so regarding the feasibility of processing petroleum contaminated soils through Hot Mix Asphalt (HMA) facilities primarily for the purposes of removing hydrocarbons (THC) from the soil. These callers believe that, with the direct-fired system used for heating and drying aggregates in a HMA facility, the THC would be destroyed. Unfortunately, this not necessarily the case. Limited testing has indicated that some of those THC will be destroyed, however a substantial portion may be exhausted to the environment.
