The work includes the supply of all labour, tools, equipment, materials, and warning and traffic guidance signs as necessary for the safe and efficient completion of the entire work. ‘The requirements specified hereafter emphasised on the performance of road markings during their functional life. The requirements are expressed by several parameters representing different aspects of the performance of road markings. Road Marking Materials ‘The road marking materials shall be of thermoplastic type and shall comply with the requirements of BS EN 1871, and shall demonstrate compliance with the relevant performance of BS EN 1436. Road marking paints shall be used for temporary road markings only and it shall comply with the requirements of MS 164. Preparation of Site Thermoplastic materials and road marking paints shall be applied only on a surface which is clean and dry. It shall not be laid over loose detritus, mud or extraneous matter or over old material or paint marking incompatible with the paint being applied, A tack coat compatible with the marking material shall be applied on the clean and dry surface in accordance with manufacturer's instructions prior to the application of thermoplastic material, If a tack coat, primer or undercoat is necessary to ensure proper adhesion of the marking paint to the road surface without bleeding or other discoloration, the tack coat, primer or undercoat shall be fully compatible with the marking paint and the road surface. The rate of application of tack coat, primer or undercoat shall be in accordance with the manufacturer's instructions and to the satisfaction of the 8.0. Where the application of a tack coat, primer or undercoat is inappropriate, the Contractor shall seek the approval of the S.O. to omit such application, 863-1 63.4 63.5 6.3.6 IKR/SPI/2012-86 Preparation of Material on Site (a) Thermoplastic Material Thermoplastic material shall be supplied in block or powder form. If the material is supplied in block form, it shall be broken into pieces, each weighing not more than 4 kg, which shall be melted in a heater fitted with a mechanical stirrer to prevent local overheating and to ensure uniform distribution of the premix glass beads or reflective elements. ‘A thermometer of sufficient accuracy shall be used during laying to ensure that overheating of the material does not occur. Once molten, hydrocarbon resins shall be used within 6 hours whereas wood and gum resins shall be used within 4 hours. The material shall not be heated beyond the manufacturer's specified temperature during application. Excess material shall be discarded on completion of application. (b) Road Marking Paint ‘All paint shall be thoroughly stirred before application to keep the pigments in uniform suspension. The use of thinners or other additives shall not be permitted unless otherwise approved by the $.0. ayin| Centre lines, Jane lines and edge lines shall be marked by approved mechanical means or as directed by the S.0. Other markings shall be applied by brush, spray, screed, hand-propelled or self-propelled machine according to the marking configuration and the type of marking material approved for use. The rate of application of the marking material for each coat shall be that recommended by the manufacturer unless otherwise specified. When more than one coat is used, the succeeding coat shall not be applied until the previous coat has fully set. ‘The drop-on glass beads or reflective elements shall be applied by pressure or gravity feed concurrently with the laying of the road marking, The rate of application of these clements is recommended to be not less than 400 g/m? in order to achieve the specified minimum initial coefficient of retroreflected luminance as specified in sub- section 6.3.9. Road markings of a repetitive nature other than centre lines, lane lines, etc., shall, unless otherwise decided by the S.0., be set out with stencils which comply with the size and spacing requirements as shown on the Drawings. Protection of Markings All markings shall be protected from traffic until they have dried sufficiently so that no pick-up by vehicle tyre will occur. 863-2 63.7 63.8 JKRISPI/2012-86 ‘Thickness (a) Thermoplastic Material Thermoplastic material shall be laid to the following thicknesses and shall be measured from the surface of the pavement:~ i) For synthetic hydrocarbon resin binder - soreed lines: not less than 2 mm, nor more than 5 mm; - extruded lines: not less than 2mm, nor more than 5 mm; - sprayed lines other than yellow lines: not less than 1.5 mm; - sprayed yellow edge lines (for ‘no parking’, “no waiting’, ete.): not less than 0.8 mm, ii) For gum or wood resin binders - screed lines: not less than 3 mm nor more than 5 mm; - extruded lines: not less than 2 mm, nor more than $ mm; - sprayed lines other than yellow lines: not less than 2 mm; - sprayed yellow edge lines (for ‘no parking’, ‘no waiting’, etc.): not less than 2 mm nor more than 3 mm, The thickness shall be measured by using a suitable device such as micrometer gauge or callipers, on samples of markings laid on steel plates beneath the application machine during the laying operations. In addition, thickness measurements shall also be carried out on laid road markings at an interval of 250 meters on each line, and on each other markings, (b) Road Marking Paint Road marking paint shall be laid to give a wet film thickness of not less than 315 microns and not more than 400 microns. Tolerance on Width The tolerance on the specified width of the marking shall be within the range of + 10% and minus 0%. 6.3.9 Retroreflectivity Requirements Retroreflectivity is the ability of a road marking to reflect light from a vehicle’s headlight back to the driving position of a vehicle. Initially it will be determined by the amount of glass beads or reflective elements spread on the marking. The continuing performance of the marking is determined by the amount and quality of glass beads included in the body of the marking. 863-3 6.3.10 JIKR/SPI/2012-86 Glass beads or reflective elements used in premix thermoplastic shall comply with the requirements of BS EN 1424, while drop on glass beads or reflective elements used on the road markings shall comply with the requirements of BS EN 1423, and shall demonstrate compliance with the relevant performance of BS EN 1436. For retroreflection under car headlamp illumination in dry condition, the minimum initial coefficient of retroreflected luminance Rx shall be 300 med/m’/Ix. For retroreflection under car headlamp illumination in wet condition, the minimum, initial coefficient of retroreflected luminance Ry shall be 75 med/m*/lx. The Contractor shall demonstrate that the markings comply with the retroreflectivity requirements by testing them with a retroreflectometer or equivalent, in accordance to BS EN 1436 Annex B. The test shall be carried out not more than seven (7) days after laying, at an interval of 250 meters on each line, and on each other markings. Skid Resistance Requirement If so stipulated in the BQ or in the drawings for skid resistance requirement, the Contractor shall demonstrate that the markings comply with the skid resistance requirement by testing them using the standard British Pendulum apparatus, in accordance to BS EN 1436 Annex D. Skid resistance of road markings will decrease in value due to the effects of traffic and weathering. For both permanent and temporary road markings, the skid resistance shall be in the SRT units and shall be not less than 45SRT units. A modified version of the UK. formula shall be used to convert readings to an equivalent skid resistance value at 35°Celsius, which is a more realistic reference temperature to be adopted for the tropics. The skid resistance value shall be determined using the formula:- SRT(35°C) = (100 + t) X SRT 135 where, SRT (35°C) = equivalent skid resistance value at 35°Celsius t= temperature of water lying on the road at the time of testing SRT = mean of five readings as the skid resistance value The test is only applicable for road markings with 300mm width or more and shall be carried out not more than seven (7) days after laying. 863-4 IKR/SPH/2012-86 6.3.11 Defective Materials or Workmanship Materials which are defective or which have been applied in an unsatisfactory manner or to incorrect dimensions or in a wrong location, shall be removed by approved chemical or mechanical means. To the extent necessary, the road pavement shall be made good and the markings reapplied all at the Contractor's own expense and to the approval of the 8.0. ‘Where directed by the S.0., existing markings shall be removed in the same manner as above, 6.3.12 Clearing Up The Contractor shall clean up all spatters, splashes and smirches of the marking materials completely to the satisfaction of the 8.0. 6.3.13 Opening to Traffic The completed road markings shall not be opened to traffic until the material has fully set and this will usually be not less than 1 hour after the material has been laid. 6.3.14 Removal of Road Markings ‘The unwanted road markings shall be removed from the pavement in such a way to avoid any possible confusion of motorist especially in wet conditions. The Contractor shail removed the road markings completely and to the satisfaction of the S.O by blasting, grinding, scraping, burning off or jabbing action using a suitable blade tool without damage to the underlying road pavement. The Contractor shall seek the approval of the S.O. for removal by burning off since this technique is not recommended where the public are close to works, as the fumes are toxic. Removal by painted over with paint of a colour to closely match the surrounding road surface shall not be allowed. Any excessive damage to the pavement shall be repaired by the Contractor to the satisfaction of the S.O. Any road markings incorrectly removed shall be remarked by the Contractor to the satisfaction of the S.O The Contractor shall clean up and remove from the roadway all materials and debris from his operations and leave the roadway clear for use by the public. $6,.3-5
