Roadwork crews withing the City of Littleton are sealing cracks in roadways around several neighborhoods with this fall’s mild temperatures. Crack sealing helps maintain and extend the life of a road. For the first time, contractors hired by the city are placing biodegradable toilet paper over freshly sealed areas to keep the tar in place and off of people’s shoes, bicycles, cars and tires. The tar used for crack sealing is really sticky and doesn’t dry quickly. Rather than close freshly sealed areas to keep the tar in place, placing toilet paper over the cracks meshes with the sealant, is cost effective, and rain and traffic will help it dissipate in a few days.
According to the Colorado Department of Transportation’s (CDOT) 2014 Best Practices Guidelines, “After a sealant application, a blotting material may be needed to reduce or minimize tracking of the sealant by vehicle tires. The need for this will depend on the type of sealant material, the ambient temperatures, and how quickly the road will be open to traffic.” Toilet paper is a commonly used and inexpensive blotting material.
CDOT also recommends “applying sealant in the spring and fall when cracks are open a moderate amount and before deicing applications have started.”
