A project using sulphur as a substitute for 30% of the asphalt binder in the standard design for Type D and hot-sand asphaltic concrete pavement was incorporated into a project on US 69 in Texas. The sulphur-asphalt (S/A) mix compares very favorably with the straight asphalt mix. The same methods and equipment were used in the construction of both with the exception of the turbine mill used to produce the S/A binder. Tests indicated an increased stability in the S/A mixes over the straight asphalt mixes. Tests also showed that the operation generated hydrogen sulphide, sulphur dioxide and sulphur levels well below the toxic levels. Details of the test section and laydown operation are briefly described.
