Book Description
8 different road roughness measurement devices were evaluated in the field by a statistical approach to that used in the analysis of the AASHO road test data. 45 pavement sections, including flexible, rigid, and overlay types of construction, were evaluated by the measuring devices and by three rating panels. The measurement devices, included the Bureau of Public Roads types of roughometers, four different types of profilometers, a texture meter, an accelerometer system, and an instrument for measuring variation in tire pressures. Regression equations which relate pavement rating and objective measurements are presented for each instrument.

Book Description
The feasibility is investigated of various acoustic (sonic), nuclear, and electrical techniques for nondestructive measurement of Portland cement and bituminous concrete pavement thickness both during and after construction. Recommendations are made for equipment development and field testing of three specific methods that could potentially result in such measurements with the desired degree of speed and accuracy.
