COMPACTION OF THIN ASPHALT LAYERS

Several test sections of thin asphalt layers were laid in order to ascertain how compaction is influenced by mix composition (tandem roller- with or without vibration, vibratory roller, pneumatic tires roller-of varying wheel pressure), and number of roller passes (0,2,5, or 13). Given the same number of passes, the vibrating rollers gave better compaction results than those with pneumatic tires, with the difference being greater the harder the mix was to compact (i.e. with the crushed sand mix). as far as the varying wheel pressures of the tires rollers is concerned, weight will no longer facilitate compaction after reaching a certain maximum. Nuclear measurements on cores of the relation between density and depth show that under the influence of rolling (especially with tired rollers) the density becomes more homogeneous over the depth, particularly in the case of the natural sand mix. Creep tests on core samples showed no clear relation between the density and the stiffness of the mix, the roller type, or the number of passes.
