Which helps in returning the post to its original position without damaging the product or vehicle. The retro reflective tape applied on the post shall be as per ASTM D 4956 and shall be of pattern less reboundable. The message area for printing shall be 100 x 400 mm (minimum). The height of the post shall be 750 mm(minimum), the width of the post shall be 120 mm (minimum). the weight of the flexible urban delineator not less than 1500 grams. The flexible urban delineator shall be applied in gaps in median, traffic islands, dangerous bends, roundabouts etc as per direction and entire satisfaction of Engineer-In-Charge.

Providing and fixing Twin Molded Shank RPM out of ASA or HIPS or ABS or any other suitable material approved by the Engineer with reflective panels consisting of number of lenses containing single or dual prismatic cube capable of providing total internal reflection of light entering the lens face. The road stud width shall be 125mm minimum and height shall be not less than 10 mm and not exceeding 20mm. The marker shall support a load of 13635 Kg minimum tested in accordance with ASTM D4280. Two cylindrical polymer shanks of not less than 20mm diameter and not less than 30mm length shall be molded in the RPM body. The slope of the reflective road stud shall be 35 +/- 5 degree to base and area of each lens shall not be less than 13 sq. cm. The stud shall also meet all the testing conditions of ASTM D4280 and must be fixed to the road surface using the epoxy adhesive only as recommended by the manufacturer. Each reflector lens must have Coefficient of Luminous Intensity (C.I.L) as specified in Table 16.48 CPWD Specifications 2019, Vol II. The road stud shall comply to tests as per ASTM D 4280. The road stud shall be tested to support a load of 13635 Kg minimum and for Coefficient of Luminous Intensity (C.I.L) from government laboratory (CRRI/ARAI/ICAT/CPRI) as per direction and entire satisfaction of Engineer-In-Charge.

Providing fixing Flexible Median Markers as per IRC 79:2019 which shall be of tough, high impact resistant, injection-molded, thermoplastic body with property of flexibility to provide high durability and U shape structure having rebound/bounce back property.
