A new method of road repair surprised the residents of the U.S. city of Littleton, Colorado. The city workers covered roadway cracks with toilet paper, Colorado Daily reported.

Officials say toilet paper was applied with a paint roller over freshly laid tar used to fill asphalt cracks. The paper absorbs the oil from the tar as it dries, keeping it from sticking to pedestrian's shoes or car and bike tires. The biodegradable paper will break down and be gone in a few days.

It was reported that Littleton crews have used bathroom tissue to help seal up cracks along more than 120 streets. This method has been successfully used in other American cities.
