Technical, Economic, and Environmental Investigation of

The use of additive in asphalt mixture is one of the appropriate solutions to technically modify the properties of asphalt concrete. An additive is able to strengthen asphalt mix by modifying its technical features. On the one hand, it is possible that additives can increase financial costs thus making their use impractical.

The use of sulfur in hot mix asphalt (HMA) (known as SEA or sulfur-extended asphalt) was originally tried in the 1970s and continued into the 1980s (1). The hot liquid sulfur was used in HMA as a binder extender (replacing a portion of the asphalt binder) and a mixture modifier.

A laboratory mix design procedure would need to simulate the field curing process in order to correlate the properties of laboratory- prepared mixes with those of field mixes. Since the curing of foamed asphalt mixes in the field occurs over several months, it is impractical to reproduce actual field curing conditions in the laboratory.
