Fritz Jooste,

This report documents the results of the tests on the southbound lanes, also referred to as the "South Tangent. Another report currently in being written presents the results of tests on the northbound lanes (North Tangent). 2.0 HVS TEST OBJECTIVES AND SCOPE OF WORK The main objective of the series of tests on the South Tangent was to evaluate the fatigue behavior of the fast setting hydraulic cement concrete/Portland cement concrete blend under the influence of accelerated wheel loads. It was assumed that the behavior of this mix is similar to that of a pure FSHCC mix. Thirteen HVS tests were undertaken on the South Tangent during the period 07/15/1998 to 05/21/1999. This report summarizes the results and observations of all HVS tests conducted on the South Tangent. Included in this report are all test sections on the plain jointed (no-dowels, no-tie bars, standard lane width) sections with concrete thicknesses of 100 mm, 150 mm, and 200 mm. All of the data summarized in this report is included in the Pavement Research Center electronic database. 3.0 HVS TEST PROGRAM The HVS tests on the South Tangent are listed in Table 3.
