Major Patching

Due to base deterioration, large portions of the roadway are cutout or milled out and replaced with new asphalt base. Generally, these are areas deteriorated by frost conditions and are known as “blowouts”. At a later time this area is resurfaced with a wearing course.

Overlay of Wearing Course

Used where base is in good condition, but surface-wearing course is deteriorated.  After milling surfaces, leveling courses may be applied and drainage problems corrected whereupon a wearing course of blacktop is applied.

Crack Sealing

Cracks are sealed with asphalt sealant, generally preparatory to some type of a wearing surface treatment.

Cold Surfacing (Micro-surfacing)

A surface treatment applied 1/2″ or less in thickness, utilizing water based oil and aggregate slurry applied over the entire roadway. This treatment is generally used where roads have a good solid super structure but the surface is in need of minor restoration to maintain safe driving conditions. Milling of deteriorated areas and leveling for drainage may be done prior to this treatment.

Oil and Chip

This treatment is used on many of the Township’s roadways, especially the older and more deteriorated road surfaces. The process allows for and application of oil and chip over the entire surface in order to provide a sealed surface and thus reduce the amount of water penetration into the roadway base. It allows for sealing of minor surface cracks, especially during the summer months when high temperatures cause it to become soft and pliable.

Traffic Marking and Traffic Signs

The Road Department is responsible for the installation and application of all municipal street signs and traffic markings on township right-of-ways. The Department installs the signs and markings in accordance with the Pennsylvania Department of Transportation, Rules and Regulations.

Vegetation Control

The Road Department annually prunes and trims overgrown vegetation along its right-of-ways in order to maintain sight distances at corners, clear corridors on straight-away, and to allow sunlight to penetrate to the roadway to affect a dry road surface. A side benefit of this vegetation control program is a need for less ice melt as shaded road surfaces are eliminated.
