MIFFLINTOWN — Maintenance treatment on roads in Juniata County continue next week, according to a news release from the Pennsylvania Department of Transportation.

The treatments, known as “oil and chip” are known to restore friction of the surface to enhance traction and extend the pavement life between resurfacings.

Flaggers in the roadway will provide traffic control during daylight hours on the following roadways.

• The entirety of Route 1003 (Tennis Park Road); Monday;

• The entirety of Route 1004 (Shade Road); Monday;

• The entirety of Route 1005 (Leonard Hill Road); Monday;

• Route 235 between Route 35 and the Juniata-Snyder County line approximately four miles north of McAlisterville in Fayette Township; Tuesday and Wednesday;

• Route 2017 between Route 2018 (Swartz Valley Road) and the Juniata-Snyder County line approximately 3.25 miles north of Loschs in Monroe Township; Wednesday through Friday;

• The entirety of Route 2016 (Church Street) in Monroe Township; Wednesday through Friday.

PennDOT announced some of this work for the week of May 26, but weather delayed work progress.

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.
