3. Section-500 TABLE 508.1.1 : QUANTITIES OF MATERIAL REQUIRED FOR 10 m 2 AREA Aggregate Quantity (a) Nominal size 13.2 mm (passing 22.4 mm sieve and 0.18 m 3 retained on 11.2 mm sieve) (b) Nominal size 11.2 mm (passing 13.2 mm sieve and 0.09 m 3 retained on 5.6 mm sieve) Binder Total 0.27 m 3 (a) For 0.18 m 3 of 13.2 mm nominal size stone at 52 kg 9.5 kg bitumen per m 3 (b) For 0.09 m 3 of 11.2 mm nominal size stone at 56 kg 5.1 kg bitumen per m 3 Total 14.6 kg Prepare the mix in a hot mix plant of suitable size with separate dryer arrangement for aggregate. 4. Mixing should be thorough to ensure that a homogenous mixture is obtained. The temperature of bitumen at the time of mixing should be in the range of 150 0 C to 163 0 C and that of aggregates 155 0 C to 163 0 C, provided that the difference between the temperature of aggregate and the binder should not exceed 14 0 C. If modified bitumen is used, temperature should be as recommended in Subsection 512. The temperature at the time of discharge of the mixture should be between l30°C and 160°C. 5. Locate hot mix plant near the work site. The mixed material should be transported quickly to the site of work and laid uniformly by suitable means. 6. The premixed material shall be spread on the road surface with rakes. 7. Commence rolling with 80-100 kN rollers (three-wheel or tandem type), beginning from the edge and progressing towards the centre longitudinally. (On superelevated portions, rolling should progress from lower to upper edge parallel to centre line of pavement). Continue rolling operations till a smooth uniform surface is achieved and all roller marks are eliminated. Each pass should have an overlap of at least one-third of the track made in the preceding pass. 8. Correct any high spots or depressions noticed after the roller has passed over the whole area once by removing or adding premixed material and recompacting. 9. Provide a seal coat to the surface immediately after laying the carpet as per details in Sub-section 510. 10. Ordinarily, the road may be opened to traffic after laying the seal coat with restrictions given in Subsection 510. 102
B. Quality Control Requirements 1. Materials (a) Aggregates 103 Quality Assurance Handbook for Rural Roads Aggregates shall conform to the physical requirements indicated in Table 508.1.2 (b) Binder TABLE 508.1.2 PHYSICAL REQUIREMENTS OF STONE AGGREGATE Property Test Specification Particle shape Flakiness index (IS:2386 Part 1) Max. 25 % Strength Aggregate Impact Value (IS:2386 Part 4) Max. 30 % Durability Soundness (IS:2386 Part 5) Sodium sulphate Max. 12 % Magnesium sulphate Max. 18 % Water absorption Water Absorption (IS:2386 Part 3) Max. 1 % Stripping Coating and stripping of bitumen aggregate Minimum retained mixture. (IS:6241) coating 95 % The binder shall be a penetration grade bitumen of a suitable grade S-65/90 depending on climatic condition of the area or of the type as specified in the Contract. Where modified binder is specified Subsection 512 should be followed. 2. Horizontal Alignment The edges of the carriageway with Premix Carpet should be correct within a tolerance limit of (±) 20 mm in plain and rolling terrain and (±) 30 mm in hilly terrain. 3. Surface Level The tolerance in surface level of the surface dressing would be (±) 6 mm for machine laid work and (±) 10 mm for work executed manually. 4. Surface Regularity The maximum allowable difference between the pavement course and a 3 m straight edge shall not exceed 8 mm for both the longitudinal profile and the cross profile. 5. Quality Control Tests 5.1 Tests Prior to Construction The quality control tests to be carried out prior to construction are indicated in Table 508.1.3.
