HIGH TEMPERATURE PNEUMATIC COMPACTION

A FIELD TEST IS DESCRIBED WHICH COMPARES THE CORE DENSITIES AND AIR PERMEABILITIES OBTAINED ON ASPHALT CONCRETE /AC/ WHEN COMPACTED BY SEVERAL ROLLING SEQUENCES. THE DIFFERENT PROCEDURES USED INCLUDE STEEL WHEEL ROLLING ALONE AND IN COMBINATION WITH PNEUMATIC COMPACTION MADE UNDER A VARIETY OF TEST CONDITIONS. THE CONDITIONS INCLUDE BOTH LOW AND HIGH PRESSURE TIRES, MODERATE AND HIGH PAVEMENT COMPACTION TEMPERATURES, AND THE USE OF PNEUMATIC ROLLERS FOR INTERMEDIATE OR BREAKDOWN COMPACTION. PNEUMATIC COMPACTION WAS CONDUCTED AT PAVEMENT TEMPERATURES AS HIGH AS 275 F WITHOUT PREHEATING THE TIRES BY MEANS OF A RELEASE AGENT ADDED TO THE WATER LUBRICATING THE TIRES. PAVEMENT DENSITIES AS HIGH AS 95 PERCENT OF LABORATORY COMPACTED VALUES WERE OBTAINED AT 195-220 F. VALUES LESS THAN 90 PERCENT WERE OBTAINED BY PNEUMATIC COMPACTION AT 135 F, THE HIGHEST TEMPERATURE POSSIBLE TO ROLL WITHOUT THE AC STICKING TO WATER-LUBRICATED TIRES. /AUTHOR/
