This report covers work completed up to the present time on the measurement of irregularities affecting the riding qualities of high type bituminous Pavements. The largest portion of this study was devoted to new construction involving Class I, Plant Mix Bituminous Concrete pavements although other roads were studied on the same basis for comparison purposes.
The purpose of the project was to evaluate the roughness characteristics of high type bituminous pavements by measuring the surface irregularities and interpreting them in terms of existing specifications. In evaluating these pavement irregularities two methods were used; one with which the surface was actually measured for deviation from the tolerance limits; and the other which necessitated the use of a road-roughness device that provided a measure of the riding qualities in terms of inches of roughness per mile.
