Abstract
Disclosed is a process for producing high grade asphal
tic materials from low grade bituminous materials and the
improved products resulting therefrom. More particularly,
there is disclosed a process for preparing novel high quality
paving grade asphalt cements and novel roofing grade
asphalts from poor and marginal quality bituminous mate
rials by passing an oxidising gas through the bituminous
starting material in the presence of a carbonate salt as
catalyst, for example, sodium carbonate or bicarbonate.
Other carbonates and sesquicarbonates may also be used.
