This report assess the availability and pricing of sulfur with respect to sulfur extended asphalt paving mixtures. The assessment includes a review of past and current trends as well as sulfur estimates up to the year 2000 for the United States and specifically the State of Washington.

This summary report overviews two previously issued study reports. One report assesses the availability and pricing of sulfur with respect to sulfur extended asphalt (SEA) paving mixtures. The second study report concerned a laboratory oriented testing program which was principally used to examine the durability and aging characteristics of SEA paving mixtures.

This is a detailed and accessible examination of the properties, behaviour, and uses of sulfur cement and concrete in the construction industry. It discusses the basic properties and behaviour of sulfur cement and concrete materials, evaluates new sulfur market applications, and much more.

The subject report contains the most comprehensive published description to date of equipment, materials, quality control procedures, and construction procedures used during the construction of pavement sections with sulphur-extended-asphalt (SEA) binders. It also highlights design procedures and emissions control monitoring used for the project. The reports graphic account will provide useful information to the following class of highway professionals who plan to use SA binders in construction: administrators, materials engineers, construction supervisors, quality control specialists, pavement designers, maintenance engineers, and environmental control specialists.

The purpose of the project constructed in Florida was to design, build, and evaluate a bituminous base course using sulphur as an asphalt cement extender. This evaluation was developed in a manner consistent with procedures used in base satellite projects constructed throughout the state. The test sections are located in Alachua County and were incorporated as a part of the new construction of a four-lane divided roadway. The project itself consists of one control section and seven test sections, each approximately 600 feet (183 m) long. Four of the test sections have SEA binders.
