• Abstract:
  The durability of markings on concrete pavement has always been a problem. Recently, recesses have been ground into the pavement to allow the markings to sit below the surface of the concrete in hopes that this would reduce the wear on the marking material. However, this method is time-consuming and expensive. In 1999 - 2000 on project NH 0342-034, Castle Rock Construction modified the screed bar on a paver to form grooves for both shoulder stripes and the skip stripe on a 4-lane divided highway - US 34 east of Kersey from about mp 122 to 124 both east and westbound. The contractor welded pieces of 1/4 inch-thick steel to the bottom of the paver screed to form the grooves as the concrete was placed. The grooves for the shoulder stripes are 4.5 inches wide; the groove for the skip stripe is 8 inches wide. This study evaluated the condition of the thermoplastic and pavement marking tape stripes through several winters to see if the grooves provided significant protection for the stripes. Placing lane markings in shallow grooves in the pavement results in considerably longer marking life, making the highway safer for drivers.
