The results of a grading test on a sample of lateritic gravel intended for the sub-base course of a road project are shown below. The Atterberg limit tests gave a liquid limit of 42 and a Plastic Limit of 20. Table 1 for Question 1 3.18 1.18 0.425 | 0.300 | 0.212 | 0.075 Size Percentage passing (%) i) 37.10 19.00 6.70 100.00 | 91.82 46.17 33.88 28.99 | 17.43 15.82| 14.22 11.72 Plot the grading curve Determine with clear reasons whether the material meets the minimum ii) requirements of the index properties for the sub-base course in accordance with the GHA Specification for T2. iii) What will be your recommendation for using the material?
