“3.03 COMPACTION

A. Compaction shall be carried out only when the moisture content of the material is in the range -2% to +2% of the optimum moisture content, where the optimum moisture content is as defined by the maximum modified dry density determined by Vietnamese Standard 22TCN 333:06.

B. Each layer shall be compacted to the full width by the methods in the Contractor’s approved method statement confirmed by satisfactory trials. Rolling operations shall begin along the edges and progress gradually towards the center in a longitudinal direction. On super elevated sections rolling shall begin at the low side and progress towards the high side. The rolling operation shall continue until all roller marks are eliminated and the layer is uniformly compacted and the aggregates firmly keyed. Any irregularities or depressions that develop shall be corrected by loosening the material at these places and adding or removing material until the surface is smooth and uniform. Along headers and walls and at all places not accessible to the roller the Subbase, Base and Leveling Courses material may be compacted with tampers or compactors. At the end at each shift the surface of the Base, Subbase and Leveling Courses shall be shaped and sloped to prevent ponding of rain water.

C. The aggregate Subbase, Base surfaces, which are to receive a prime coat, shall be compacted to produce a stable, tightly locked surface with no open pores and suitable for priming.

All coarse aggregates shall be tightly locked in place.

The locking process shall be achieved by compaction only. Under no circumstances shall any form of fine aggregate be added to the surface to assist the locking process. Vibration shall not be used in the final stages of the compaction of the surface. Pneumatic rollers or static steel wheeled rollers shall be used for the final surface compaction unless excessive breakdown or degradation of the aggregate Subbase, Base and Leveling Courses occurs, in which only pneumatic rollers shall be used.

D. When the underlying material is soft or yielding compaction of the Subbase, Base shall be stopped and the underlying materials rectified in a manner approved by the Engineer.

E. Compaction of each layer shall continue until a satisfactory field density has been achieved. Insitu densities shall be determined in accordance with Vietnamese Standard 22TCN346-06.

F. Proof rolling shall be conducted after finishing by a roller of at least 25 tons weight. If the deflection is more than 3mm the layer shall be replaced at the Contractor’s expense.”
