CONCLUSIONS

FIGURE 1 Data gathering and analysis strategies. pavement types were concrete, bituminous, bituminous over concrete, and concrete-bituminous over concrete. All test sections were 0.2 mi long and selected to represent a wide range of roughness and rut depths of pavements in Minnesota. The test sections were conveniently located around the St. Paul area. Table 1 shows the locations and types of the selected eight test sections. the IBM-based road profilers are commercially manufactured with slight hardware and software modifications. Table 2 provides a list of the participating road profilers and their types.
