M&L for preparation of old black top surfaces by brushing with wire brushes for removing caked mud etc., sweeping with brooms and finally fanning the cleaned surfaces with using air blowers to remove all loose dirt, rubber deposits complete and applying Polymer Modified Emulsion (PME) by spraying with machine having penetration value 10-20mm and initial setting time of 4-5 hours but not more than 8 hours. First coat with 0.6 Ltr (undiluted) PME diluted in 0.60 Ltr water to be appleid uniformally on each 1.0 Sqm area mixed with mineral filler as recommended by manufecturer's of PME and ensure uniform finish of PME on flexible surface with mechanical application through spraying machine and using specially designed mopper for mopping the surface complete all as per manufacturer's instructions and all as specified and as directed by Engr-in-Charge. Notes: The tenderer shall take into consideration for the following points while quoting his rate for this item (a) Friction parameters shall be between 0.30-0.60 after application of PME contractor will make necessary arrangment for procurement of portable Skid resistance Tester (PSTR) and carry out necessary testing as directed without any extra cost of Govt. (b) The work shall be carried out through authorized and qualfiied applicators of the manufacturer only.
