High Friction Surface Treatment (Source: PennDOT)
Lane restrictions are scheduled on Route 202 between Ash Mill Road in Buckingham Township and Old York Road in New Hope on Monday, July 1, and Tuesday, July 2, from 9 a.m. to 3 p.m., for high friction surface treatment (HFST), the Pennsylvania Department of Transportation (PennDOT) announced Friday.
The work is a part of a $4.7 million project to apply high friction surface treatment to various state highways across the Philadelphia Region.
Why apply high friction surface? Road surfaces become polished in areas where drivers brake often, like going around curves, down steep roads, or at an intersection, according to PennDOT. This makes vehicles skid more because there is less friction between the tires and the road surface. Wet road surfaces can also reduce pavement friction and cause skidding or hydroplaning.
High Friction Surface treatment is added to the top of a road surface. It uses materials, such as bauxite, to create more friction on pavement. These materials, called aggregates, are high quality and are less likely to wear down than normal pavement. Having greater friction helps to keep vehicles in their lane on slippery pavement around curves and helps the driver stop, says PennDOT.
In other traffic news, Peddlers Village will close Route 263 from Aquetong Road to Street Road from 9 to 11 a.m. on Saturday, June 29, according to Solebury Township officials. There will be limited access for arrivals or departures from area residences, and a police officer will be posted at the intersection of Bellinghamshire Place and Route 263. The closure is to facilitate a 5K race.
Do they re-pave first and then top with the high friction surface treatment?
