Neighborhood Street Resurfacing Program

Williamson County uses two different types of resurfacing products subdivision streets. The straight sections of roadway will receive what is called a "seal coat"and the cul-de-sacs will receive what is called a "fog seal".

A "seal coat" is a preventive maintenance surface treatment designed to preserve and extend the life of a street. It protects an aging pavement surface and seals up small cracks to keep water out of the pavement. The process starts by spraying a thin layer of liquid asphalt over the pavement. It is followed by the spreading of a thin layer of small rock. The surface is then rolled with a rubber tire roller and the street is reopened to traffic. Excess gravel is swept up by a vacuum street sweeper soon thereafter. It takes about a couple of months for the new surface to completely cure and lock the surface firmly into place with the road open to regular traffic.

The "fog seal" process received its name because it is applied on the surface of the existing pavement in the form of a fine mist. The asphalt that will be utilized is called a Tire Rubber Modified Surface Sealant (TRMSS) and is an asphalt that has been modified to be more rigid than typical asphalt and can be driven on directly. For this reason, there will not be any rock applied as part of the resurfacing. Consequently, the friction from vehicle tires will cause the fog seal to wear more quickly than the seal coat that was applied on the straight sections of streets, and cul-de-sacs will need to be resurfaced more frequently. 

If you have any questions or concerns, please call the Williamson County Road and Bridge hotline at 512-943-3393.

 
Preparation for Resurfacing

There are some important steps in a successful resurfacing application that occur months before the product is actually applied. County Road and Bridge crews will start preparing your streets in the Fall and Winter for resurfacing operations that will occur the following Spring and Summer.

Notifying Residents

Road and Bridge will notify residents in advance of the work by door hangers, flashing message signs or static message signs. If your subdivision is receiving door hangers, it can be expected that the Green door hanger will be placed approximately 2 weeks in advance of the work and the Orange hanger will be placed approximately 2-3 days in advance. If your subdivision is receiving a flashing message board, it can be expected that the message board will be placed approximately a week in advance of the work. After receiving advance notification, please check here to see if your street is scheduled for the next two days of work. This list is updated daily.


NOTE: Please do not run sprinklers on your designated resurfacing day.
