TxDoT begins ‘seal coat’ operations in county

E-mail Print PDF

Texas Department of Transportation maintenance crews have begun work adding a “seal coat” surface to several sections of highway in Hopkins County to smooth out road surfaces as well as extend the lives of the state-maintained thoroughfares.

Work crews were scheduled to begin applying the asphalt overlay Wednesday on FM 71 at the Peerless spur, then move today to FM 3505, the entry road to Cooper Lake’s South Sulphur Unit.

Between Friday, May 22, and on or about Monday, June 1, highway construction crews will be sealing the approximately six-mile stretch of FM 69 between FM 71 and FM 900.

Maintenance crews will finish up — weather permitting — around Thursday, June 4, by applying the seal coat on a short section of FM 852 south of Pickton, from FM 269 to the Wood County line.

Contractor crews will perform additional seal coat work later in the summer, according to Tray Turner with the Paris District Office of the state highway department.

As with most highway construction projects, motorists will need to pay attention to work zone warning signs. They should also be prepared for delays of up to 10 minutes in some areas.

When passing through work zones, drivers are reminded to slow down to avoid accidents, not to mention broken windshields from loose gravel. (Those flying rocks are none too gentle when they hit road crew workers, either.)

“Plan and schedule enough time to drive safely, be patient and stay calm,” stated Turner. “Remember that highway crews are working to improve the road so that your future drive will be better.”

The seal coat process involves putting a thin layer of asphalt on the road surface, then covering it with a rock overlay. The asphalt layer seals most cracks, thus keeping moisture from collecting underneath the surface — one of the major causes of roadway deterioration. The layer of rock, meanwhile, provides more friction where the rubber meets the road.

Seal coating is considered to be extremely cost effective, which explains why it is the most utilized preventive maintenance treatment on the Texas state highway system. According to TxDoT’s “Seal Coat and Surface Treatment Manual,” a seal coat typically costs about $1 per square yard. Conversely, an asphalt concrete overlay costs about $5 per square yard.
