Abstract

A proposal is made that the scope of activity and objectives of the committee be enlarged and that its name be changed to "road surface properties related to vehicle performance". The objectives of the committee on the basis of its enlarged scope are to: (1) assemble researchers in the measurement of skid resistance, road roughness, tire wear, tractive resistance, noise, glare and light reflection, and electrotastic properties in relation to various types of road surfaces, (2) encourage organizations and help determine the need for research on subjects relating to these subjects, (3) coordinate and bring to the attention of highway engineers and highway users research results which will lead to the establishment of acceptable road surface standards to provide greater safety, economy and comfort in the operation of motor vehicles, and (4) increased membership to be compatible with the enlarged scope of activity. A brief review is presented of the research on skid resistance, road roughness and related properties of road surfaces. Test proposals for measuring various properties and for establishing standards of measurement and standards of design, construction and maintenance are also discussed. The following road roughness indicators are described and compared: The bpr roughness indicator and the california university road roughness oscillograph recorder.
