EVALUATION OF EXPERIMENTAL OPEN GRADED FRICTION COURSES
The Maryland State Highway Administration with the cooperation of the Maryland Asphalt Association through its member contractors began construction of experimental test pavements in conjunction with normal paving contracts. This joint effort, which began in 1972, was an attempt to develop those bituminous mix designs producing the highest possible friction values using locally available aggregates. The results of continuing friction measurements on the various mix designs are evaluated. It appears that there is small difference between Marylands standard SN, St and an open graded plant mix seal when using the same aggregate. Plant mix seals do seem to offer some benefit in the area of reduced spray during rain and some reduction of tire-pavement noise. /FHWA/
