The annual street maintenance program provides routine preventive maintenance and full-scale repair for the City's public streets (not including Fort Worth Highway, Bankhead Highway, and IH-20, which are maintained by TxDOT).
Each winter, staff performs a street condition survey to review the quality of each street and any repairs that might be needed. This survey, combined with information such as ride quality, traffic counts, average speed, visibility, available budget, and other factors, are used to determine which street repairs will be performed in any given year.
Pothole patching is performed throughout the year, and involves cleaning the distressed area (and cutting around the distress if necessary), filling with cold mix asphalt material, and rolling until the original grade is matched. Pothole patching is a cheap and temporary way to improve ride quality, but it does not improve the condition of the road.
Crack sealing is a preventive measure performed during the spring. A hot emulsion is spread on cracks to seal them and prevent further water infiltration which would cause additional damage to the subgrade.
Full-depth patching involves cutting and removing distressed sections down through the subgrade, performing subgrade repairs (often with a concrete or lyme treatment), and placing a 2" layer of hot-mix asphalt concrete (HMAC) back to the original grade of the road. This treatment has historically been used as a slightly more long-term solution for areas with recurring potholes, rutting, and alligator cracking.
Chip sealing is a paving method that involves the installation of small rocks and a hot asphalt emulsion, often in one or two coats. This is a cost-effective method for providing a durable driving surface, particularly in rural areas or on roads with modest traffic counts. The resulting surface is flexible, allowing it to breathe as temperatures and soil conditions fluctuate. However, the ride quality is often worse than asphalt or concrete roads, although it does improve as traffic wears the surface to a more even consistency. Most of the original neighborhood roads in Hudson Oaks are chip sealed.
Overlay repairs can be performed when the subgrade is in good shape, but the drive surface is not. Overlay repairs involve milling off the asphalt surface and replacing it with a new 2" layer of HMAC.
Full-depth reconstruction involves milling off the original drive surface, performing subgrade repairs (often 8"-12" deep with a concrete or lyme treatment), and paving a new 2" layer of HMAC. Depending on conditions and available budget, a 6"-8" concrete section may be poured instead of HMAC.
