vsrEPA Project Summary
Evaluation of VOC Emissions
from Heated Roofing Asphalt
Peter Kariher, Michael Tufts, and Larry Hamel
A short-term in-house project to
charecterize emissions from a simulated
asphalt roofing kettle was performed at
EPA/AEERL. Hot asphalt surfacing and
resurfacing has been identified as a
possible significant source of volatile
organic compound (VOC) emissions that
may affect human health and contribute
to the ozone non-attainment problem.
This Project Summary was devel-
oped by EPA's Air and Energy Engi-
neering Research Laboratory, Research
Triangle Park, NC, to announce key find-
ings of the research project that is fully
documented in a separate report of the
same title (see Project Report ordering
information at back).
The purpose of the study was to col-
lect, identify and semi-quantitate as many
compounds as possible that are discharged
during the open heating of roofing asphalt
and relate them to the amount volatilized
into the air
Types 1, 2, and 3 mopping grade as-
phalts were chosen for this study. They
constitute more than 90% of roofing as-
phalt used Samples of each type of as-
phalt were placed in a simulated roofing
kettle, heated to predetermined tempera-
tures, and sampled for volatile and semi-
volatile organic emissions. Compounds
identified during this study were alkanes,
aromatics, a ketone, and an aldehyde.
