• Abstract:
  In this report the Texas Transportation Institute (TTI) compares the relative performance of sand-asphalt-sulfur pavements and a deep asphalt concrete pavement. Elastic and fatigue properties of the sand-asphalt-sulfur pavement materials were studied in considerable detail over a period of years. The material moduli and fatigue properties were used to calculate stress, strain and deflections under an 18-kip dual tire, single axle load using computer programs. Thicknesses of the test items were selected in accordance with expected load and service life. Post construction testing of the experimental project will be conducted by TTI in cooperation with the Texas Department of Highways and Public Transportation over a period of three years.
