SPAM Resurfacing Projects

On February 11, City Council awarded a construction contract to Fuquay, Inc. for the 2018 SPAM Resurfacing Projects.

The 2018 SPAM Resurfacing Projects involve placing a new driving surface on streets in the project area. The new surface essentially preserves the street, while providing a new wearing surface to drive on. Before the new surface is applied, there is some prep work that must be done on the streets. Prep work involves repairing damaged areas in the pavement and crack sealing larger cracks. The new surface that will be applied is called a “chip seal.” To create the new surface, a layer of oil is sprayed onto the street surface. After the oil is sprayed, a layer of small diameter rocks (called “chips”) is spread onto the oil. Rubber tired rollers are then used to make sure the chips are pushed into the oil. The oil used preserves and covers the existing asphalt and acts as a glue to hold the chips onto the surface. The chips provide the new driving surface for the streets.

When the chip seal is first applied there will be excess chips on the street surface. It will give the appearance of loose gravel on the street surface. This is normal and these excess chips will be swept from the surface in a few days after the application. The reason why we have to wait a few days to sweep up the excess is because the oil needs some time to cure. Sweeping too early would strip the chips out of the oil layer, effectively removing the new driving surface.

One of the benefits of a chip seal is that once the chips have been spread onto the oil, the surface can be driven on. Some care should be taken when driving on the fresh surface. Sudden acceleration and sudden stops should be avoided. Such actions can strip the chips out of the oil, much like sweeping too early can. Also, avoid sitting still while turning the steering wheel sharply. Any movement, even very slow movement, while turning is preferable. Please drive slowly during this time period as well. Traveling at, or below, the 20 mph speed limit on the streets is highly recommended.

The City’s contractor is going the prep work in the project areas now. Once the prep work has been completed, the contractor will have to wait until warmer, drier weather to apply the new surface. This will most likely occur in early Summer. Please check back here for project updates and more information as the project progresses.

Project Areas

UPDATE - MARCH 17, 2020

Work has begun on the resurfacing project. Our contractor is working in the Greenfield Village subdivision now. The work underway is part of the prep work before the new driving surface can be applied. The prep work involves removing section of asphalt that have significant amounts of “alligator cracking.” While the pavement may seem ok, the alligator cracking is a sign of a base failure underneath the pavement. Once the asphalt is removed, the base material is re-compacted and new pavement is placed. The new pavement layer will be much thicker than the existing pavement. Because of the thickness, the new pavement must be placed in two layers. Once the first layer of new pavement has been placed and compacted, it may need to cool down some before the next layer can be placed. This is why a patch may look unfinished – the new pavement not even with the rest of the street. The contractor may do the first layer in a few patches and then come back to place the final layer in each patch.

On Tuesday the 17th, the contractor will begin doing prep work on Live Oak between FM 3009 and Schertz Parkway. Some of the repair areas are fairly large, so traffic will be restricted to a single lane while the repairs are made. The contractor will have flaggers and a pilot car to help guide motorists through the project area. Please take a different route if you are able to, or allow extra time to drive down Live Oak. Thank you for your patience and understanding as we complete these repairs.
