Soil compaction process for potholes
1. Vacuum out any standing water in the excavated area.
2. Fill the bottom of the excavated area with ¾ inch road base to top of exposed utilities,
ensuring to bed any exposed pipes or conduits.
3. If excavated area is too small or too deep to start with Jumping-Jack, a breaker bar and a
hand tamper will be used to fill in any voids beneath pipes and conduits.
4. Repeat steps 2 and 3 until Jumping-Jack can be used.
5. When compacted fill reaches ~4 inches below grade elevation, utilize hot mix asphalt to
fill in the remaining space making sure to leave a slight bulge of no more than 1/4in
above grade elevation to account for any settling from vehicle traffic.
6. Seal-coat all asphalt gaps to city specifications. (Section 806 pg.54) Twin Falls City code.
** Pneumatic tamper will replace Hand-Tamper where conditions permit.
