DETERMINATION OF EQUIVALENT AXLE LOADS FOR MINNESOTA FLEXIBLE PAVEMENTS

The traffic phase of Minnesota's AASHO Road Test satellite study consisted of an attempt to determine the total traffic load experience which each of the 58 test sections in the project was subjected to since its construction. Extensive traffic studies were performed in 1964 and again in the 1969-1971 period to obtain the required data. The traffic loading, in terms of summation of equivalent 18,000-lb. single axle loads, was required so that a correlation with other structural and performance data could be made. This correlation was part of the development of a new flexible pavement design procedure. Large variations occurred between individual test sections in vehicle weights and type classification. Test section data were compared with rural Minnesota statewide trends. Sigma N18 projection difference of less than 30 percent for a particular design project do not significantly affect the ultimate pavement design. /FHWA/
