SPECIFICATION FOR THE REINSTATEMENT OF OPENINGS IN ROADS
S11 Ancillary Activities
S11.1 Traffic Signs, Road Markings, Studs and Verge Markers
1) Prior to the opening of any works to traffic, all traffic signs, road markings, studs and verge markers removed during the works shall be reinstated to a permanent or temporary standard. Temporary traffic signs, road markings, studs and verge markers shall be permitted for up to 10 working days following completion of the permanent reinstatement.
2) All traffic signs, road markings, studs and verge markers removed during works shall be reinstated at their original location, wherever possible. Where any traffic signs, road markings, studs or verge markers cannot be reinstated at their original locations, they shall be permanently reinstated to a new layout in accordance with the Traffic Signs Manual: Chapter 5 and the Traffic Signs Regulations & General Directions.
3) Where the layout of existing traffic signs, road markings, studs or verge markers is not in accordance with the Traffic Signs Manual: Chapter 5 and the Traffic Signs Regulations & General Directions, and the Authority notifies the Undertaker prior to the commencement of works, the layout of all traffic signs, road markings, studs or verge markers to be reinstated following the works shall be determined by agreement. In this event, if the Authority provides any new traffic signs, studs or verge markers, to replace obsolete or previously damaged items removed during the works, then the Undertaker shall install such items as part of the permanent reinstatement of the works.
S11.1.1 Traffic Signs, Studs and Verge Markers
1) Wherever possible, all traffic signs, studs and verge markers removed during the works shall be re-erected on completion. Where the original items cannot be re-erected, they shall be replaced using items of equivalent type, colour and dimensions.
S11.1.2 Road Markings
1) Prior to their permanent reinstatement, temporary road markings may be made using quick drying, durable paint, adhesive strip or like materials of similar colour and dimensions to the original markings.
2) Road markings removed during the works shall be permanently reinstated using materials of equivalent colour and dimensions, subject to the following requirements:
a) For small reinstatements affecting up to 2.5 m overall length of road markings, alternative materials may be substituted for the existing, subject to the following:
i) Road marking tape may be used in place of thermoplastic markings or pavement marking paint.
ii) Pre-formed thermoplastic markings may be used in place of hot applied thermoplastic materials.
iii) No alternatives may be used in place of specialist materials such as rib markings.
b) Except where otherwise specified by the Authority, the retro-reflectivity and skid resistance of all yellow and white lines shall comply with BS EN 1436, as follows:
i) Dry retro-reflectivity to Table 2 Yellow - Class R0 White - Class R2
ii) Wet skid resistance to Table 7 Yellow - Class S1 White - Class S3
3) Unless otherwise agreed by the Authority, all white thermoplastic road markings shall be treated with surface-applied glass beads.
4) Thermoplastic road marking materials with synthetic resin binder shall be laid to the following thickness:
a) Screed lines - 3.5 mm 1.5 mm
b) Sprayed yellow edge lines (No Waiting, etc.) - 0.8 mm minimum
c) Sprayed lines, other than yellow - 1.5 mm minimum
d) Extruded lines - 3.0 mm 0.5 mm
S11.2 Street Furniture and Special Features
Street furniture and other special features, such as tactile paving removed to facilitate road works, shall be replaced in the same position and layout before opening the road to traffic and pedestrians. Items removed to facilitate road works must be carefully stored and maintained during the works. Advice on replacement may be provided by the Authority.
S11.3 Traffic Sensors, etc.
Where excavation is planned at or near to traffic sensors, advice regarding precautions to avoid damage shall be sought from the relevant Authority before work commences.
S11.4 Sewers, Drains and Tunnels
1) An Undertaker executing road works that involve breaking up or opening a sewer, drain or tunnel shall complete the reinstatement works to the reasonable requirements and satisfaction of the responsible Authority.
2) In the case of a public sewer, the "responsible Authority" shall mean Scottish Water (i.e. the water service company for Scotland).
3) In the case of any other sewer, drain or tunnel, the "responsible Authority" shall mean the owner (or the Authority, body or person) responsible for the management or control of the sewer, drain or tunnel.
S11.5 Test Holes
Test holes of 150 mm diameter or less are not excavations for the purposes of this Specification and shall be reinstated to a permanent standard within 10 working days of completion of all associated work on the site.
1) General
a) Prior to reinstatement, all test holes should be made safe and maintained in a safe condition.
b) Test holes up to 25 mm diameter shall be reinstated to an immediate permanent standard.
c) Test holes larger than 25 mm diameter may be reinstated to an interim standard, if required
d) In modular surfaces, preference should be given to the lifting of individual modules prior to the drilling of test holes, whenever reasonably practical.
e) In unmade ground, test holes shall be tamped closed or filled with appropriate materials.
2) 50 mm Diameter or Less
a) In paved surfaces, test holes shall be reinstated using a fine aggregate, bound with cement or bitumen for the upper layers, as appropriate, and compacted in layers of l00 mm thickness, or less, to finish flush with the surface. Alternatively, a flexible sealing plug may be installed flush with the surface.
b) In bituminous surfaces, all sealing plugs shall be coloured black (or dark grey).
c) In modular or concrete surfaces, sealing plugs up to 25 mm nominal diameter may be coloured black (or dark grey) or white (or light grey).
d) In modular or concrete surfaces, sealing plugs greater than 25 mm nominal diameter shall be coloured white (or light grey) and may be installed with black (or dark grey) or white (or light grey) coloured sealant.
3) 50 to 150 mm Diameter
a) In paved surfaces, test holes shall be reinstated using a fine aggregate, compacted in layers of 100 thicknesses, or less, and surfaced with appropriate cementitious, cold or hot-lay bituminous materials.
b) The surfacing materials and compaction shall comply with the relevant requirements of Appendix A3, A4, A5, A6, A7, A9 or A10, as appropriate, to finish flush with the surface.
4) Greater than 150 mm Diameter
a) In paved surfaces, test holes shall be reinstated using Class A Graded Granular Material, placed in layers of 100 mm thickness, or less, compacted using mechanical plant and surfaced with appropriate cementitious, cold or hot-lay bituminous materials. The surfacing materials and compaction shall comply with the relevant requirements of Appendix A3, A4, A5, A6, A7, A9 or A10, as appropriate, to finish flush with the surface.
b) In flexible surfaces, the edge sealing requirements of Section S6.5 3) shall apply.
