EVALUATION OF BITUMINOUS SURFACES USING FINER AGGREGATES

Bituminous mixtures utilizing aggregates falling outside current gradation specifications were used as wearing courses on several low volume county roads in three counties in Minnesota. Evaluation consisted of visual observations, including photographic records, and frictional resistance testing. After five years in service, it appears that the use of finer gradation aggregates will result in satisfactory bituminous wearing courses on low-volume roads. /FHWA/
