• Abstract:
  Four different measuring devices for use in evaluating highway surface roughness were investigated in this study. Two, the CHLOE Profilometer (1), and the Bureau of Public Roads Roughometer with mechanical integrator (newer Bureau of Public Roads Roughometers are equipped with an electronic integrator) (2), are well known and have been compared previously (3). The others, the Portland Cement Association Roadmeter (4) and the Mays Road Meter* are recent developments which warrant some description, especially the latter, since no description of it has previously appeared in the literature. The aims of our study of these instruments were: 1. To examine the field-worthiness of the several systems. 2. To determine the validity of their respective measurements. 3. To determine the effects on their results of such variables as operating speed, driver characteristics, operating temperatures, and other factors.
