2 Initial Conditions of the Road Initial Conditions of the Road Initial Conditions of the Road

3 The nature of gravel road accessing area for development

4 Category material in situ is G5-G6 (Colto RSA) The state of the Road Section

5 Cutting of the bypass lane Cutting of the bypass lane

6 Mixing continued Mixing continued

7 Ripping of the Road Process 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.

8 Rocks and stones visible after ripping the surface

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

13 The Manual distribution of RoadCem The Manual distribution of RoadCem

14 Evenly distributed RoadCem Evenly distributed RoadCem

15 Manual distribution of cement

16 Integrating Cement Mixing the cement and RoadCem into the matrix utilizing a Motograder

18 Removal of larger stones, rocks and litter

19 The windrow method was used to mix the soil to obtain optimum homogenous mix The windrow method was used to mix the soil to obtain optimum homogenous mix

20 Wetting of the matrix until OMC is achieved for compaction

21 Compaction Process

22 Roller compaction until 95 % Mod Aashto compaction is achieved

23 the final cut and leveling to obtain the correct profile and camber
