Availability of sulfur has considerably grown in many countries. In the Gulf region, particularly in Saudi Arabia due to the increase in number of oil gas industries, the production of sulfur as a co-product has also increased. The investigation of new applications for sulfur in construction has become a challenge for civil engineers. Sulfur Extended Asphalt (SEA) used for paving roads is ...

Sulfur extended asphalt Sulfur as an Additive for Asphalt. Sulfur-extended asphalt (SEA) binders are formulated by replacing some of the asphalt cement (AC) in conventional binders with sulfur. Binders that have sulfur asphalt weight ratios as high as 50 50 have been used, but most binders contain about 30 wt % sulfur. Greater latitude in design is possible for SEA paving materials, which are ...

Sulfur-extended asphalt has been used in dense-graded mixtures with sulfur/asphalt binder mass ratios from 20/80 to 40/60, and at times even up to 50/50 (3). The emulsified portion of sulfur performs as an asphalt extender while any excess sulfur performs as a mix filler or stabilizer. The allowable sulfur concentration in the binder depends on the properties of the asphalt (6). On a long-term ...

The most attractive market for Sulfur Extended Asphalt is in road, parking lot, airport runway and taxiway construction and maintenance. Sulfur was used as an asphalt extender and modifier in the 1970s and 1980s. However, this technology was discontinued in the late 1980s and 1990s due to higher sulfur market price, limited availability of sulfur, and the side effects of elemental sulfur ...

The probability of more sulfur being recovered as a result of more restrictive environmental legislation resulted in developing a number of different processes for producing sulfur-extended asphalts (SEA). There are two reasons for considering the use of sulfur in asphalt mixes: (1) to improve the mix quality and (2) to reduce the cost. The latter depends mainly on the relative costs of sulfur ...
