PAINT STRIPE AND GLASS BEAD STUDY - REPORT I-FIELD TEST SECTION

ONE HUNDRED INDIVIDUAL TEST SECTIONS INVOLVING OVER 230 MILES OF PAVEMENT WITH MORE THAN 24,000 INDIVIDUAL CENTER- LINE STRIPES WERE INCLUDED IN THIS STUDY. ALSO, 69 MILES OF CONTINUOUS EDGELINES WERE PLACED AND STUDIED. PAINT THICKNESS RANGED FROM 5.4 TO 20.2 MILS. BEAD APPLICATION RATES VARIED FROM 1.4 TO 9.3 POUNDS PER GALLON. ON THE BASIS OF AREA COVERED THE BEADS VARIED FROM .010 TO .068 POUNDS PER SQUARE FOOT OF STRIPE. NINETY-NINE PERCENT OF THE STRIPES WERE PERFORMING SATISFACTORILY AT THE END OF ONE YEAR. SOME OF THE STRIPES ON ASPHALT WERE IN TEST NEARLY TWO YEARS AND STILL PERFORMING SATISFACTORILY. IT HAS BEEN DEMONSTRATED THAT THINNER PAINT STRIPES AND LOWER BEAD APPLICATION RATES THAN COMMONLY RECOMMENDED CAN BE UTILIZED. THE STUDIES SHOW THAT PAINT THICKNESS CAN BE SAFELY REDUCED TO TEN MILS AND BEAD RATE TO FOUR POUNDS PER GALLON AND HAVE BETTER REFLECTING, FASTER DRYING, MORE DURABLE STRIPE THAN AT 18 MILS AND SIX POUNDS OF BEADS PER GALLON. STUDIES SHOW THAT IN KANSAS PAINT CHIPPING IS THE MOJOR PROBLEM OF PAINT LOSS. WEAR OR ABRASION IS A MINOR PROBLEM. THERE IS ALSO MINOR LOSS DUE TO SNOWPLOW OPERATIONS, PATCHING, CRACK FILLER AND JOINT COMPOUND. THE SERVICE LIFE OF THE PAINT STRIPES IS OFTEN MORE DEPENDENT UPON THE SURFACE CONDITIONS OF THE ROAD THAN UPON THE THICKNESS OF THE PAINT FILM. /AUTHOR/
