CORRELATION OF ROUGHOMETER AND SKID TESTS WITH PAVEMENT TYPE, DESIGN AND MIX

A STUDY TO CORRELATE RIDING QUALITIES ON RECENTLY CONSTRUCTED BITUMIONUS PAVEMENTS WITH MIXED DESIGN POLICIES AND CONSTRUCTION PRACTICES WAS CONDUCTED ON THE FOLLOWING TWO TYPES OF BITUMINOUS MIXTURES ON PLAIN-MIX PAVEMENT PROJECTS: SAND-ASPHALT AND ASPHALTIC CONCRETE. THE SKID RESISTANCE MEASUREMENTS AND ROAD ROUGHNESS MEASUREMENTS RESULTED IN THE FOLLOWING CONCLUSIONS: (1) STABILITIES ON SAND-ASPHALTS, USING TWO-IN. DIAMETER SPECIMENS, RANGE FROM A MINIMUM OF 150 LB. TO THE MAXIMUM OF 1800 LB. BY THE HUBBARD FIELD METHOD, (2) STABILITIES ON ASPHALTIC CONCRETE RANGED FROM 500 LB. TO 4500 LB. STABILITY ON 6-IN. DIAMETER SPECIMENS BY THE MODIFIED HUBBARD FIELD METHOD, (3) ROAD ROUGHNESS MEASUREMENTS FOR SAND-ASPHALT PAVEMENTS RANGED FROM A MAXIMUM OF 176 TO A MINIMUM OF 54 IN. PER MI., (4) ROAD ROUGHNESS MEASUREMENTS FOR ASPHALTIC CONCRETE PAVEMENTS RANGED FROM A MAXIMUM OF 117 TO A MINIMUM OF 57 IN. PER MI., (5) SKID RESISTANCE TESTS ON WET SAND-ASPHALT PAVEMENTS AT 40 MPH RANGED FROM A SKID DISTANCE OF 69 FT. TO A SKID DISTANCE OF 126 FT., (6) SKID RESISTANCE TESTS ON WET ASPHALTIC CONCRETE PAVEMENTS AT 40 MPH RANGED FORM A SKID DISTANCE OF 81 FT. TO A SKID DISTANCE OF 111 FT., (7) CONSIDERING ONLY NEWLY LAID PAVEMENT, THE LOWEST ROUGHNESS INDEX WAS OBTAINED WITH LOW STABILITY SAND-ASPHALT MIXES, AND (8) WHERE THE PREPONDERENCE OF SAND PARTICLES OCCUR BETWEEN THE NO. 40 AND NO. 200 MESH SIEVES, THE FRICTIONAL RESISTANCE OF THE SURFACE IS COMPARATIVELY LOW.
