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.

The chip seal application is complete except for Live Oak. This application will have to wait until the curb, gutter, and sidewalk project is completed. All areas have been swept as per the contract requirements. However, the contractor has received some complaints from residents in the Estates at Wilson’s Preserve directly. In an attempt to help address these complaints, they are doing some additional sweeping in there today and in Greenfield Village. They are also checking to make sure they have cleaned off the manholes and water valves in the project area. They are in the process of setting up the striping on Randolph.
The chip seal has been applied to almost all of the areas in the project. There is one block of Randolph that was delayed to wait for the Randolph reconstruction to be completed. This block is expected to be completed in the near future when weather conditions are more favorable. The other area not completed is Live Oak. This chip seal will need to wait until after the planned curb gutter, and sidewalk project is completed. The curb, gutter, and sidewalk project is expected to be bid in July.
The chip seal was applied to the Estates at Wilson’s Preserve this week. With this chip seal application, the vast majority of the chip seal has now been applied. The contractor began doing the initial sweeping and cleanup of the chip sealed areas this week. The “cleanup work” also includes touching up portions of the chip seal as needed. This work will continue into next week.
Chip seal was applied to the streets in Deer Haven, Lone Oak, and Greenfield Village this week. On Monday, the contractor will drop back to Deer Haven and do the initial sweeping and touch up any areas that need it. They will do the same in Lone Oak. After they take care of sweeping and touching up, they will apply the chip seal to The Estates at Wilson’s Preserve. After the chip seal has been applied to the Estates at Wilson’s Preserve, the majority of the chip seal work will be completed.
The prep work is complete for the project. We are now waiting for drier, warmer weather to apply the chip seal. It may be a couple of months before this happens. We will issue another update before the chip seal application starts, so please check back for more information.
The required base repairs for the project have been completed. The contractor is working in the Greenfield Village area installing concrete valley gutters at some intersections. This work will continue into next week. When the valley gutters have been completed, all of the prep work for the project will be finished. We will have to wait until we have warmer, drier weather before the chip seal can be applied to the surface.
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.
