3. Section-400 (ii) Grading Requirements The aggregate shall conform to the grading requirements indicated in Table 406.2 TABLE 406.2: GRADING REQUIREMENTS OF AGGREGATE FOR WET MIX MACADAM FOR BASE COURSES. IS Sieve Designation Maximum percent by weightPassing the sieve (iii) Optimum Moisture Content : Optimum Moisture Content shall be determined in accordance with IS:2720 (Part 7) 2. Horizontal Alignment The edges of WMM base will be correct within a tolerance limit of (±) 30 mm in plain and rolling terrain and (±) 50 mm in hilly terrain. 3. Surface Level The tolerance in surface levels of the WMM would be (±) 10 mm: (A grid of 10 m by 2.5 m may be formed to check the surface levels). 4. Surface Regularity The maximum permissible undulation measured with a 3 m straight edge, in the longitudinal profile shall be 10 mm and for cross profile the irregularity shall not exceed 8 mm. 5.
