Compaction For Road Foundations
Compaction for foundation consist of road aggregate base a and base b has a way of how certain to be implemented so that the results obtained meet the specifications.
a) Immediately after mixing and formation of the end, each must be compacted complete with suitable compaction equipment and adequate approved by the
Board of Directors of Engineering, until the density of at least 95% of the maximum dry density "modified" as a determined by AASHTO T 180, method D.
b) Rubber wheels roll machine is used for final layer compaction, when the static roll machine steel wheels damage or excessive degradation of the pavement sirtu.
c) Compaction should be done only when water content of the material is in the range 3% less than optimum levels to 1% more than optimum
water content, where the optimum water content are as determined by the density maximum dry "modified" is determined by AASHTO T 180, method D.
d) The operation should start rolling along the edge and moved bit by bit axis toward the street, in a lengthwise direction. In which was part of
"super-elevation", rolling should begin at the low and move little by little towards the more high. Rolling operation must be continued until the entire roll
former machine becomes no looks and layers are compressed evenly.
e) Material along kerb, stone edge, wall, and places inaccessible roll machine timbris compacted with mechanical or compaction others are approved. More
