Sulphur-extended asphalt: reaction kinetics of H2S

The interest in sulphur-asphalt mixtures was especially high in the 1970s and 1980s. At present, there is concern about the behaviour of sulphur-extended asphalts (SEA) because of the problems that could arise during the recycling of old SEA pavements.
