This report provides a summary of a laboratory study on sulfur extended asphalt paving mixtures. The following major features were included in the study:
- Design of laboratory experiment which included the use of mixtures which contained various amounts of sulfur, two viscosity levels of asphalt cement, and two types of aggregate (basalt and granite).
- Evaluation of mixture design methods (Hveem and Marshall).
- Determination of optimum binder contents.
- Evaluation of mixture durability and aging characteristics.
- Development of revised mixture design criteria.
