Conclusions

  1. 1.

    The character of the process of compacting a PAC mix on sand and on clay materials has substantial differences. On sand vibro-compaction is more effective with a high value of acceleration, 100 m/sec2; on clay materials the highest quality of compaction occurs with insignificant acceleration of vibro-compaction, 40 m/sec2.

  2. 2.

    It was established that PAC mixes are compacted more effectively on sand having a modulus of deformation not lower than 40 MPa. If the modulus of deformation of the base is lower, it is recommended to strengthen and additionally compact it.

  3. 3.

    On clay materials having a low modulus of deformation, the quality of compaction of the PAC mix is low, and therefore it is recommended to strengthen them.
