Georgia DOT: Sealing Cracks on the Surface of the Roadway Resumes in Polk County

February 12, 2019---11:34 A.M.


ROCKMART, Ga. – A Georgia DOT maintenance crew resumes today its work on sealing the cracks on the surface of State Route (SR) 6 in Polk County. Work will proceed daily Tuesday through Friday between the hours of 7:30 a.m. and 5:30 p.m., weather permitting.

Pavement expands and contracts with seasonal temperature changes. This movement can and does cause the surface of the roadway to crack, allowing water to seep into the roadbed. Water is the most destructive element to pavement and it has to be prevented from entering the roadway base and sub-base. Sealing the cracks with a flexible rubberized asphalt that bonds to the crack walls and moves with the pavement prevents water intrusion. As part of Georgia DOT pavement management/maintenance system, crack sealing helps to reduce pavement deterioration by restricting water penetration into the underlying base and sub-base layers. This restriction helps to maintain pavement structural capacity and limits future degradation. Sealing cracks and joints in pavements thus extends the service life of the roadway surface and pavement.
