DRY COMPACTION: MYTH OR REALITY?

LE COMPACTAGE A SEC : MYTHE OU REALITE

A dry compaction experiment was conducted during the construction of the Tahoua-Arlit road in Nigeria with a view to determining the useful utilization of the following materials with a natural moisture content: 0/1 fine sand with a sand equivalent of approximately 50 (sol b1) for building the embankment; and reg crusher run aggregate: well graded 0/100 mm gravel containing 5 to 20% fines (sol C1 and C2) for the roadbase. After a laboratory study of Proctor hammer compaction with different energies, full-scale compaction tests were carried out with vibrating rollers and with a pneumatic tyred roller following a vibrating roller. The results (mean density) showed that sand of low moisture content could be used provided that the upper part of the embankment (improved subgrade) was wetted or provided a thin layer of gravel was added. The dispersion of the results obtained with the reg crusher run aggregate did not allow to determine a dry compaction technique for this material. (TRRL)
