CITY OF SANTA ANA <br />SPECIFICATIONS <br />PROJECT NO.: XX-XXXX <br />PROJECT TITLE <br /> <br />66 <br />All striping and related roadside signage shall be in place prior to opening the lane(s) <br />to public traffic. <br />E. THERMOPLASTIC <br />Thermoplastic traffic stripes, pavement markings, crosswalks and limit lines shall <br />conform to the provisions in Sections 84-1, “General,” and 84-2, “Thermoplastic <br />Traffic Stripes and Pavement Markings,” of the Caltrans Standard Specifications and <br />these special provisions. <br />Specifications for glass beads shall be “8010-004 (Type II).” Glass beads shall be <br />premixed within the thermoplastic material prior to application and also applied to the <br />surface of the molten thermoplastic striping material immediately following the <br />application of the thermoplastic. <br />Thermoplastic material shall conform to the requirements of Caltrans Specification <br />No. PTH-02ALKYD, for Thermoplastic Traffic Striping Material, White and Yellow. <br />The binder material shall be Alkyd. Copies of the Caltrans Specification No. PTH- <br />02ALKYD are available at the Caltrans Transportation Laboratory, Sacramento, <br />California. Thermoplastic material shall conform to the requirements of Caltrans <br />Specification No. PTH-02ALKYD. <br />Thermoplastic material for traffic stripes shall be applied by extrusion method in <br />single uniform layer at the minimum thickness of 40 mils and not to exceed 50 mils. <br />The Contractor shall not begin work until a written notice to proceed has been issued <br />by the Engineer. The Contractor shall notify the City of Santa Ana - Public Works <br />Agency Engineer a minimum of two working days prior to beginning the work to <br />coordinate the work. A schedule of the streets to be re-striped for each day shall be <br />provided to the Engineer one full workday prior to striping or re-striping any streets. <br />The Contractor shall adjust the thermoplastic application rate as necessary to achieve <br />the thermoplastic application rate stated above prior to striping. Thermoplastic <br />application rate tests (up to and including 5 thermoplastic application rate tests per <br />day, including the thermoplastic application rate test at the start of each workday) <br />may be conducted at random times and locations throughout each workday at the <br />discretion of the Engineer. <br />Thermoplastic Application Rate Testing <br />The paint application rate shall be determined by passing the striper over a metal <br />plate while the paint application system is operating. The flow of glass beads shall <br />be stopped while passing over the metal plate. The Engineer shall measure <br />thickness of the applied thermoplastic immediately after application of <br />thermoplastic on the metal plate. Striping shall not continue if the proper <br />thickness of thermoplastic is not being applied. Adjustments and corrective <br />measures shall be applied to insure that the correct thickness of thermoplastic will <br />be applied. Testing of the thermoplastic application rate, as described above, will <br />505 E Central Ave <br />#B11/6/2024
