Road Marking Paint:

All paints shall be road marking paint conforming to BS6044 : 1987 ‘Specification for Pavement Marking Paints’ and made by an approved manufacturer and suitable forapplication, by the means proposed, to the specified road surfaces. The paint shall be suitable for applying by brush or mechanical means. The following
particulars of the paint shall be supplied:
1)composition (analysis by weight)
2)application (brush or spray)
3)type and maximum amount of reducer (thinner)
4)drying time (wheel dry)

Construction Methods Thermoplastic Materials:

Preparation of Road Surface:The material shall be applied only on a surface which is clean and dry. It shall not be laid over loose detritus, mud or similar extraneous matter, or over an old paint marking , or over an old thermoplastic marking which is faulty. New surfaces must be allowed to weather and compact for at least 72 hours before applying the marking. In the case of smooth polished surfaces, e.g. smooth concrete, old asphalt surfacing with smooth polished surface stones, and/or where the method of application requires or the Engineer directs, a tack coat shall be applied to the surface prior to the application. The tack coat shall be as recommended by the manufacturer of the thermoplastic material and to the approval of the Engineer. Faulty thermoplastic markings shall be removed if required by the Engineer.

B)Preparation of Thermoplastic Material:
The material shall be melted in accordance with the manufacturer’s instructions in aheater fitted with a stirrer to give a smooth consistency to the thermoplastic and such that local overheating shall be avoided. The temperature of the mass shall be within the

Range specified by the manufacturer and shall on no account be allowed to exceed the maximum temperature stated by the manufacturer. The molten material shall be used as expeditiously as possible and for thermoplastics which have natural resin binders or areotherwise sensitive to prolonged heating, the material shall not be maintained
