701 -2 Materials . 701 -2 . 1 Thermoplastic . Use thermoplastic material meeting the requirements of 971 - 1 and 971 -9 and listed on the Qualified Products List (QPL) as an approved system . The Engineer will take random samples of the materials in accordance with the Department ' s Sampling, Testing and Reporting Guide schedule . 701 -2 .2 Retroreflective Elements : Use reflective elements recommended by the manufacturer that meet the requirements of 9714 . 7 and are part of the system listed on the QPL . 701 -3 Equipment. Use equipment capable of providing continuous, uniform heating of the striping material i to temperatures exceeding 390°F , mixing and agitating the material in the reservoir to provide a homogenous mixture without segregation . Use equipment that will maintain the striping material in a plastic state, in all mixing and conveying parts , including the line dispensing device until applied . Use equipment which is capable of producing a consistent pattern of transverse bumps p positioned at regular and predetermined intervals . Use equipment which meets the following requirements : (a) capable of traveling at a uniform rate of speed, both uphill and downhill, to produce a uniform application of striping material and capable of following straight lines and making normal curves in a true arc . (b) capable of applying reflective elements to the surface of the completed stripe by automatic dispensers attached to the striping machine such that the reflective elements are dispensed closely behind the installed line . Use reflective element dispensers equipped with an automatic cut-off control that is synchronized with the cut-off of the thermoplastic material and applies the reflective elements uniformly on the entire traffic stripe surface with 50 to 60 % embedment . It I (c) equipped with a special kettle for uniformly heating and melting the striping material . The kettle must be equipped with an automatic temperature control device and material thermometer for positive temperature control and to prevent overheating or scorching of the thermoplastic material . (d) meets the requirements of the National Fire Protection Association, state and local authorities . 7014 Application . 7014 . 1 General : Before applying traffic stripes and markings , remove any material that would adversely affect the bond of the traffic stripes by a method approved by the Engineer. Before applying traffic stripes to any Portland cement surface , apply a primer, sealer or surface preparation adhesive of the type recommended by the manufacturer. Offset longitudinal lines at least 2 inches from construction joints of Portland cement concrete pavement . Apply traffic stripes or markings only to dry surfaces , and when the ambient air and surface temperature is at least 50°F and rising for asphalt surfaces and 60 °F and rising for concrete_ surface . Apply striping to the same tolerances in dimensions and in alignment specified in marking over existing markings , ensure that not more 710 - 5 . When applying traffic stripes and than 2 inches on either end and not more than 1 inch on either side of the existing line is visible . Conduct field tests in accordance with FM 5 - 541 . Remove and replace markings not meeting the requirements of this Section . - 191 - FPID ( S ) : 423186 - 1 - 5 8 - 01
