3. Section-500 B. Quality Control Requirements 1. Materials (i) Binder for Tack Coat Rapid setting bituminous emulsion Grade RS-1 complying with IS:1887 as specified in Contract. For sites at sub-zero temperature: Cutback Bitumen (Medium Curing Grade) as per IS:217. (ii) Rate of application of Binder 2. Quality Control Tests TABLE 503.1: RATE OF APPLICATION OF BINDER FOR TACK COAT The quality control tests and their frequencies would be same as for Prime Coat in Tables 502.2 and 502.3. C. Do’s and Don’ts Type of Surface Quantity of emulsion per sqm area (kg) Normal Bituminous surfaces 0.20 to 0.25 Dry and hungry bituminous surfaces 0.25 to 0.30 Granular (primed) 0.25 to 0.30 Cement Concrete Pavement 0.30 to 0.35 1. Plan the work so that no more than the necessary tack coat for the day’s operation is placed on surface. 2. Handle bituminous cutback carefully to avoid fire mishap. 504. Bituminous Macadam A. Methodology Do’s Don’ts 88 1. Do not apply tack coat when atmospheric temperature is less than 10OC or when weather is foggy, rainy or windy. 2. Do not apply tack coat on a wet surface. 3. Do not allow any equipment or vehicles on Tack Coat. 1. Prepare the base on which bituminous macadam course is to be laid and shape to the specified lines, grade and cross-section. 2. Apply tack coat over the base preparatory to laying of the bituminous macadam. 3. Bituminous Macadam should be prepared in a Hot Mix Plant of adequate capacity Ensure manufacturing and rolling temperatures for Bituminous Macadam as given in Table 504.1.

Transfer the mixed material quickly to site of work and lay by means of an approved self-propelled mechanical paver. 5. Commence initial rolling with 80-100 kN rollers (three-wheel or tandem type), beginning from the edge and progressing towards the centre longitudinally. On super elevated portions, rolling should progress from lower to upper edge parallel to centre line of pavement. Thereafter, do intermediate rolling with vibratory or pneumatic tyred road rollers. This should be followed by final rolling while the material is still workable. 6. Any high spots or depressions noticed after the roller has passed over the whole area once should be corrected by removing or adding premixed material. Rolling should recommence thereafter. Each pass should have an overlap of at least one-third of the track made in the preceding pass. Rolling should be continued till all rolIer marks have been eliminated. 7. For single lane roads no longitudinal joint is required, while for double-lane roads longitudinal joints may be required depending on the paver width. 8. For making longitudinal or transverse joint, cut the edges of the bituminous layer laid earlier to their full depth so as to expose fresh surface and apply a thin coat of binder. Lay adjacent new layer and compact flush with the existing layer. 9. Cover the bituminous macadam with the wearing course within a period of 48 hours. If there is any delay in providing wearing course the bituminous macadam surface should be covered with a seal coat before opening to traffic. B. Quality Control Requirements 1. Material The Bituminous Macadam shall be composed of aggregate meeting the physical requirements indicated in Table 504.2 and a paving bitumen of penetration grade complying with IS:73 or as specified in the Contract. The grading and binder requirements shall be in conformity with the requirements indicated in Table 504.3.
