3. Section-500 TABLE 507.1: NOMINAL RATES OF SPREAD OF BINDER AND CHIPPINGS. Nominal Chipping Size Binder (Penetration Bitumen emulsion Aggregate (mm) grade bitumen) kg/m 2 (kg/m 2 ) (cum/m 2 ) 13.2 1.0 1.5 0.010 9.5 0.9 1.4 0.008 6.3 0.75 1.1 0.004 4. The application temperature for the penetration grade binder used shall be as specified in Table 507.2. In case of modified binder application temperatures shall be as indicated in Sub-section 512. 5. Immediately after application of binder, spread clean dry stone aggregate at the rate given in Table 507.1 or as designed with the help of a mechanically operated chip spreader, in a single layer. In case of emulsion as a binder, the aggregate may be slightly damp. 6. Immediately after spreading of aggregates, roll the surface with the help of suitable road rollers. Commence rolling from the edges and progress towards the center except in super elevated portions where it shall proceed from the lower edge to the higher edge. Each pass should have an overlap of not less than one-third of the track made in the preceding pass. Spread additional stone chips to make up irregularities, if any. Rolling should continue until all aggregate particles are firmly embedded in the bituminous binder and present a uniform closed surface. 7. Where two-coat surface dressing is specified in the contract, the second coat should be applied after the first coat is exposed to traffic for 2 to 3 weeks. Procedures stated here-in-above will apply. The road may be opened to traffic 24 hours after the work of rolling is complete. In exceptional circumstances, traffic may be allowed immediately after rolling provided the traffic speed is limited to 20 km/h until the following day. 8. Where use of precoated chips is specified, the first step will be to precoat chips. The stone chips will be heated to 160 0 C and mixed with 0.75 to 1% of paving bitumen by weight heated to its application temperature. The precoated chips shall be cured for one week or till such time as they become non-sticky. B. Quality Control Requirements 1.

(ii) Grading: 99 Quality Assurance Handbook for Rural Roads The stone chippings should conform to the Grading given in Table 507.4 TABLE 507.4 GRADING REQUIREMENTS FOR CHIPS FOR SURFACE DRESSING IS Sieve Designation Cumulative percent by weight of total aggregate passing (mm) for the following nominal sizes(mm) 13.2 9.5 6.3 19.0 100 - - 13.2 85-100 100 - 9.5 0-40 85-100 100 6.3 0-7 0-35 85-100 4.75 - 0-10 - 3.35 - - 0-35 2.36 0-2 0-2 0-10 0.60 - - 0-2 0.075 0-1.5 0-1.5 0-1.5 Minimum 65% by Passing 13.2 mm Passing 9.5 mm Passing 6.3 mm weight of aggregate retained 3.35 mm retained 9.5 mm retained 6.3 mm (b) Bitumen The binder should be bituminous material, which may be as per the contract, or as decided by the Engineer. - Paving grade bitumen (IS 73) - Modified bitumen (IS 15462) - Rapid setting bitumen emulsion (IS 8887) (c) Where aggregate fails to pass the stripping test, an approved adhesion agent may be added to the binder, in accordance with the manufacturers instructions. 2. Horizontal Alignment The edges of the Surface Dressing 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 and (±) 10 mm for manually laid surface dressing. 4. Surface Regularity The maximum allowable difference between the pavement course and a 3 m straight edge shall not exceed 10 mm for longitudinal profile and 12 mm for cross profile respectively.
