  5. Mixing continued • Mixing continued

  6. Ripping of the Road Process • Ripping of the Road Process • This is to provide for the removal • of stones larger in size than 25% of the • matrix thickness of the road base. • This is to provide for the removal • of stones larger in size than 25% of the • matrix thickness of the road base.

  7. Rocks and stones visible after ripping the surface

  8. Consistency of Material • being worked with

  9. cement used

  10. Mix design • The Mix design for one cubic meter of in situ material is as follows: • Aforementioned will give the following quantities for the 1 km road section at an • average 6 meter width: • *The RoadCem bags is round up to the next whole bags

  11. The even distribution of cement, this is to meet the requirements for the mix design

  12. The Manual distribution of RoadCem

  13. Evenly distributed RoadCem • Evenly distributed RoadCem
