Different construction devices may be employed for filling the trenches. However, due to the potential ad-
ditional dynamic loads they introduce, it is essential to refrain from driving compaction equipment directly
over the infiltration ditch elements. Furthermore, caution is advised against using compaction equipment
with activated vibration motors over the designated area.
By way of example, Table 3 shows the earth covering needed for various compaction equipment when
using a split with a friction angle of
