A LABORATORY INVESTIGATION OF THE COMPACTION OF DENSE GRADED ASPHALT CONCRETE

This paper reports some of the results that have been obtained from a 3-year laboratory investigation of the compaction of dense graded asphalt concrete, that is being carried on by McAsphalt Engineering Services for the airfield section of the Canadian department of national defense. The investigation is studying the influence of three important factors affecting pavement compaction that can be controlled in the field, compaction temperature, compaction effort, and pavement mixture design. In addition to hot asphalt mixes, it is shown that a straight line relationship between compacted density and logarithm of compactive effort in this form of number of Marshall blows (semi-log plot) exists for many road building materials such as soil, sand screening, soil asphalt, soil cement, and cold asphalt mixtures. Therefore, some of the findings of the paper can also be applied to the compaction of these materials. /TRRL/
