The agency shall have to get the mix design done from approved laboratory and submit to the Engineer in charge for approval. (Va = 3.5% & Vbe= 11.50% must be considered in mix design) If the asphalt (bituminous) content is more than above, the agency shall have to bear the cost of additional asphalt. The payment shall be done on the permissible field density achieved on the site instead of density derived in the mix design. (The density obtained by mix design above 2.36 MT/M3 shall be boarn by agency)

Road marking with hot applied thermoplastic paints with reflectorising glass beads on bitumen surface providing and laying a hot applied thermoplastic compound 2.5 mm thick including reflectorising glass beads @ 250gms per sqm area, thickness of 2.5mm is excluding of surface applied glass beds as per IRC:35-2015. The finished surface to be level, uniform and free from streaks and holes. zebra Patta /bump Patta Lane/centre line/ edge line/cut Patta. The white colour marking should provide luminance coefficient on cement road shall be min 130 mcd/m2/lux and Asphalt Road shall be min 100 mcd/m2/lux during the service life during the day time. The marking should meet the performance criteria for night time reflectivity, wet reflectivity and skid resistance as mentioned in the section-15 of IRC 35-2015. Warranty for the Retro reflectivity should be two years.

The agency shall have to get the mix design done from approved laboratory and submit to the Engineer in charge for approval ( Va = 3.5% & Vbe= 11.50% must be considered in mix design ). If the asphalt (bituminous) content is more than above, the agency shall have to bear the cost of additional asphalt. The payment shall be done on the permissible field density achieved on the site instead of density derived in the mix design. (The density obtained by mix design above 2.31 MT/M3 shall be boarn by agency)
