Clean <br /> with a soft brush and weigh each sample . Abrade samples for 1 , 000 cycles with 1 . 1 lb weights <br /> and CS - 10 wheels . Clean the samples with a soft brush and weigh again . The average weight loss <br /> for the four plates shall not exceed 0 . 178 oz per plate . <br /> 9714 .3 .3 Retroreflectivity : The white and yellow pavement markings shall <br /> attain an initial retroreflectance of not less than 300 mcd/lx - mz and 250 mcd/lx , mZ , respectively. <br /> The retroreflectance of the white and yellow pavement markings at the end of the six month <br /> service life shall not be less than 150 mcd/lx m� . <br /> 9714 .4 Application Properties : Application properties shall meet the requirements of <br /> Section 710 . <br /> 9714 . 5 Packaging and Labeling : The traffic paint shall be placed in 55 gallon open - end <br /> steel drums with a re -usable multi - seal sponge gasket . No more than 50 gallons of material shall <br /> be placed in any drum to allow for expansion during transport and storage . <br /> 971 -5 Thermoplastic Materials for Traffic Stripes . <br /> 971 -5 . 1 General : Upon cooling to normal pavement temperature , these materials shall <br /> produce an adherent, reflective pavement marking capable of resisting deformation by traffic . <br /> The manufacturer shall utilize alkyd based materials only and shall have the option of <br /> formulating the material according to his own specifications . However, the requirements <br /> delineated in this Specification and Section 711 shall apply regardless of the type of formulation <br /> -227 - <br /> FPID ( S ) : 423186 - 1 - 58 - 01 <br />
