Clearfield, PA – The Pennsylvania Department of Transportation (PennDOT) announced the start of surface treatment operations, more commonly known as “oil and chip,” on several roads in Juniata County this week. This maintenance treatment seals the road surface to keep water out, restores the friction of the surface to enhance traction, and extends the pavement life between resurfacings.
PennDOT Juniata County Maintenance crews completed surface treatment operations on Route 35 between Turkey Ridge Road in Lack Township and Route 850 in Tuscarora Township earlier today and have begun work on the entirety of Route 75 in Lack Township. Flaggers in the roadway will provide traffic control during daylight hours during these operations. PennDOT anticipates work on Route 75 finishing tomorrow.
Crews will also be engaged in surface treatment operations on the following roads the remainder of the week.
- Route 3002 (Main Street/Old 22 Road) between Thompson Lane and Juniata-Perry County line approximately three miles east of Thompsontown Borough in Delaware Township; Wednesday, May 21.
- Route 2013 (Cocolamus Road) between Route 235 in Delaware Township and Route 35 in Fayette Township; Thursday May 22.
- Route 2008 (Dunn Valley Road) between Route 235 and Route 2015 (Swailes Road) in Fayette Township; Friday, May 23.
PennDOT typically employs surface treatments as a preservation strategy on roads with low traffic volumes and speed limits of 35 mph or slower. This activity extends the life of those roads by keeping water out, which mitigates the damage caused by the freeze-thaw cycle of Pennsylvania winters and delays the formation of potholes and the oxidization process.
In recent years, PennDOT District 2 has expanded its use of seal coating to roadways with higher traffic volumes and speed limits of 55 mph or faster as it strives to effectively manage and preserve its assets while being good stewards of taxpayer money.
PennDOT performs this activity in temperatures greater than 60 degrees, generally between April and September. Crews begin by sweeping the roadway clean of debris. Next, they apply emulsion oil and a layer of stone, which they then roll into place using a roller. Once cured, crews sweep any loose material from the roadway.
Generally, it takes about two days for the stones to bond to the hardened asphalt. PennDOT urges drivers to reduce their speed on roads that have received this treatment during the two-day curing period or to consider alternate routes.
