Abstract

Four types of bisphenols and their respective low molecular weight epoxy resins (I, II, III and
IV) were prepared and characterized. Each of the obtained epoxy resins was applied as an additive
(together with high temperature hardener) to two types of local asphalt (L and H types) having
different compositions.
The resulting data of the validity of the obtained mixtures concerning the improved properties of
asphalt [penetration, softening point, calculated penetration temperature susceptibility (PTI) and
penetration index (PI)] are based upon the effect of the quantity and type of epoxy resin, type of
the hardener used and also by comparison with the results obtained in presence of the commercial
epoxy resin (V) which has a specified low temperature hardener. The optimum conditions obtained
for the formulations which lead to the best properties are taken into consideration in the
application of such formulations for the improvement of the asphalt to be used in different
purposes.
Data obtained revealed that improved asphalt either (H) or (L) type with epoxy III and hardener
(1) gave highest values of softening point and penetration grade as compared with unmodified
parent asphalt.
