FRIDAY PHOTO — PAVEMENT MARKINGSPreserve Infrastructure, by Catherine Higgins.
When snowflakes fly, UDOT plows are out in full force. Plowing makes roads safer, but the scraping action of the plow blades against the pavement is tough on pavement markings.
Years of UDOT research has shown that recessing paint slightly below the pavement helps markings last three to five times longer because markings are less vulnerable to snow plows. UDOT Region Two Pavement Maintenance Coordinator Dan Betts has pioneered a method of cutting into the pavement slightly to recess the area slightly below the pavement surface.
“We are constantly looking for new products and technologies that are both cost effective and provide long term durability,” writes Ken Berg, Maintenance Planning Engineer. “We are asking pavement marking suppliers to apply a product of their choice and guarantee that it will perform for a 5 year period. Our intent is to eliminate yearly public impact from striping operations by providing the best pavement markings we can with minimal disruption to traffic.”
