r SCOPE OF WORK <br /> E. Thermoplastic (Extruded) <br /> Thermoplastic traffic stripes and pavement markings, and thermoplastic <br /> crosswalks and limit lines shall conform to the provisions in Sections 84-1, <br /> "General," and 84-2, 'Thermoplastic Traffic Stripes and Pavement <br /> Markings," of the CSS and these special provisions. (Specification in <br /> Appendix) <br /> Specifications for glass beads shall be "8010-004 (Type II)." Glass beads <br /> shall be premixed within the thermoplastic material prior to application and <br /> also applied to the thermoplastic striping material immediately following the <br /> application of the striping. <br /> Thermoplastic material shall conform to the requirements of Caltrans <br /> Specification No. PTH-02ALKYD, for Thermoplastic Traffic Striping <br /> Material, White and Yellow. The binder material shall be Alkyd. Copies of <br /> the Caltrans Specification No. PTH- 02ALKYD are available at the <br /> Caltrans Transportation Laboratory, Sacramento, California. <br /> Thermoplastic shall not exceed 40-50 mils. <br /> The Contractor shall not begin work until a written notice to proceed has <br /> been issued by the Project Manager or Designee. The Contractor shall <br /> notify the Project Manager or Designee a minimum of two working days prior <br /> to beginning the work to coordinate the work. A schedule of the streets to <br /> be re-striped for each day shall be provided to the Project Manager or <br /> Designee one full workday prior to striping or re-striping any streets. <br /> The Contractor shall adjust the thermoplastic application rate as necessary <br /> to achieve the thermoplastic application rate stated above prior to striping. <br /> Thermoplastic application rate tests (up to and including 5 thermoplastic <br /> application rate tests per day, including the thermoplastic application rate <br /> test at the start of each workday) may be conducted at random times and <br /> locations throughout each workday at the discretion of the Project Manager <br /> or Designee. <br /> F. Thermoplastic Application Rate Testing <br /> The paint application rate shall be determined by passing the striper over a <br /> metal plate while the paint application system is operating. The flow of glass <br /> beads shall be stopped while passing over the metal plate. The Project <br /> Manager or Designee shall measure thickness of the applied thermoplastic <br /> immediately after application of thermoplastic on the metal plate. Striping <br /> shall not continue if the proper thickness of thermoplastic is not being <br /> applied. Adjustments and corrective measures shall be applied to ensure <br /> City of Santa Ana Page 12 of 71 <br />
