3. Section-500 TABLE 504.2: PHYSICAL REQUIREMENTS FOR AGGREGATES FOR BITUMINOUS MACADAM Property Test Specification Particle Shape Flakiness Index IS:2386 Part 1 Max. 25 per cent Strength Aggregate Impact Value IS:2386 Part 4 Max. 30 per cent Durability Soundness IS:2386 Part 5 Loss in Weight SodiumSulphate Max. 12 per cent Magnesium Sulphate Max. 18 per cent Water Absorption Water Absorption IS:2386 Part 3 Max. 2 per cent Stripping Coating and Stripping of bitumen- aggregate Min. retained coating: mixtures IS:6241 95 per cent. In colder regions of India or where the percent passing 0.075 mm sieve is on the higher side of the range, appropriate bitumen contents may be upto 0.5 percent higher, subject to the approval of the Engineer. 2. Horizontal Alignment The edges of the bituminous macadam base should 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 level of the bituminous macadam would be (±) 6 mm. 4. Surface Regularity The maximum allowable difference between the road surface and a 3 m straight edge would be 12 mm for longitudinal profile and 8 mm for cross profile. 5. Quality Control Tests 5.1 Tests Prior to Construction TABLE 504.3: COMPOSITION OF BITUMINOUS MACADAM IS Sieve (mm) Cumulative Per cent Passing by weight of Total Aggregate 26.5 100 19 90-100 13.2 56-88 4.75 16-36 2.36 4-19 0.03 2-10 0.075 0-5 Bitumen content, % by weight of total mixture 3.3-3.5 Bitumen penetration Grade 35 to 90 The quality control tests to be carried out prior to construction are indicated in Table 504.4. 90
5.2 Tests During Construction 91 Quality Assurance Handbook for Rural Roads TABLE 504.4: QUALITY CONTROL TESTS PRIOR TO CONSTRUCTION Type of Test Frequency 1.

Aggregate Impact Value Test (IS:2386 Part 4) One test on representative sample per km length from each source identified by the Contractor 4. Flakiness Index Test (IS:2386 Part 1) Two tests per source 5. Bituminous Stripping of Aggregate Test (IS:6241) One test per source 6. Water Absorption (IS:2386 Part 3) -do- 7. Soundness Test, if water absorption of aggregate -doexceeds 2% (IS:2386 Part 5) The quality control tests to be carried out during construction are indicated in Table 504.5. Table 504.5: QUALITY CONTROL TESTS DURING CONSTRUCTION Type of Test Frequency 1. Grading of Aggregate (IS:2386 Part 1) Atleast one test per day. 2. Binder Content Atleast two tests per day. 3. Density of Compacted Layer Atleast one test per day. 4. Temperature of Binder before mixing Regularly 5. *Temperature of mix during laying and compaction Regularly 6. Thickness of compacted layer Regular, at close intervals 7. Aggregate impact value (IS:2386-Part 4) At random one test per km *Temperature measurement will be done by using metallic contact thermometer with digital display
