I sent this issue to the Street Department and was informed that Norman has a proactive program on pavement preservation to seal cracks in the surface to provide many additional years of service life before costly repaving becomes required. Tar is not used to fill the pavement cracks. The method the city employs uses a flexible rubber placed under high heat that remains pliable but will not become liquid in the hot Oklahoma summer heat. Many locations in our city have considerable cracking and this method of preservation has been used for over five years without issue. Without performing preservation methods such as this, significant failures will occur causing great hazard to the motoring public on city maintained roadways.

Thank you
