A profilometer known as the "CHLOE Profilometer" developed by the Road Test Staff of the AASHO Road Test at Ottawa,Illinois, was used in a study to determine whether the AASHO serviceability rating method is adaptable and desirable for Californiapavements, and if profiles obtained with the California Profilograph could be incorporated into the serviceability index formula.
The study consisted of obtaining longitudinal profile data, using both the CHLOE Profilometer and the California Profilograph.Ten sections of pavement were involved, including both asphaltic and portland cement concrete varying in condition from excellentto poor. Also included was some data from an asphalt concrete test road built as a cooperative test project by San Diego Countyand the Asphalt Institute. Statistical methods were used to evaluate the data. Electronic modifications were made to both systems tofacilitate the accumulation of data.
