With Only One Chance to get it Right, Major Drag Strip Upgrades at Wild Horse Pass Motorsports Park are Pushed Back


Chandler, ARIZ. (August 07, 2013) – After consulting with NHRA, construction professionals involved in constructing drag strips, and others, Dick Hahne, president of Wild Horse Pass Motorsports Park has made the decision push back tearing out the first 750 feet of the drag strip until October.

The reason for the delay all comes down to time.  Curing time that is.  The optimum curing time for the concrete that will replace the first 750 feet of the track is 27 days.  Trying to achieve a 27 day curing time during Arizona’s hot summer months is going to pose a challenge as it will naturally cure more quickly.  After spoke to NHRA and other industry professionals, they are all in agreement that pouring concrete in October will maximize the goal of achieving the optimum curing time of 27 days.

There’s no need to worry though.  Our local drag racing community will surely have their opportunity to saddle up and try to tame the “Wild Horse.”  Wild Horse Pass Motorsports Park is fiscally sound and will see through all of the improvements to the multi-purpose motorsports venue to completion.  The decision to delay the upgrades to the track have the full support of the NHRA, the Gila River Indian Community, the Sun Valley marina Corporation and Copper Train Development.

The work on the drag strip will begin on October 14th and be completed by December 15, 2013, at which time Hahne intends on having a December Blowout on the updated track.  Local drag racers and more will be invited out to start laying rubber down on the track in preparation for both the NHRA Heritage Series’ and the NHRA Arizona Nationals’ stops at the track.  The delay in construction will also ensure the drag strip is available for Bob Bondurant’s October 11th – 13th 80th birthday celebration, a weekend combination of a car show and auto racing.

Just because the drag strip updates have been pushed back does not mean that other upgrades to the facility are not well under way.  Currently, thousands of feet of wiring, to include both electric and audio, are in the process of being replaced.  Hahne is also about to “pull the trigger” on upgrading and resurfacing the East road course.  Quite familiar with asphalt, Hahne knows the turn around time on the road course upgrades will be quick.

From updates and upgrades to the drag strip, the East road course, timing and scoring to the PA system, good things are happening.  Hahne says that by the end of the construction and renovations, Wild Horse Pass Motorsports Park will be a facility that is good for everyone from the local racer to John Force.

    The biggest problem in hot weather is excessive moisture loss from the concrete surface This can be serious for thin concrete members, such as slabs, that have a large surface exposed to the weather. Surface evaporation is affected by a combination of four factors: concrete temperature, air temperature, relative humidity, and wind speed. Placing concrete in hot weather is complicated by the fact that the hydration reaction generates heat, adding to the problem of excessive evaporation.

    Crazing. If you pour a slab on a hot, windy day without proper precautions, several defects can result. One defect, known as crazing, causes fine surface cracks in a chicken wire pattern that are especially visible if the slab is dampened. Crazing results from too much surface evaporation during the initial curing period. It is a cosmetic problem, not a structural problem. Applying a curing compound or sealing the slab with plastic helps to prevent crazing; this should be done as quickly as possible after the slab is finished.

    Plastic shrinkage cracks. A more serious problem, plastic shrinkage cracks, can happen when moisture evaporates from the slab while the concrete is still “plastic” – that is, wet and workable. This typically happens on a windy day, leaving short, parallel cracks (6 inches to 3 feet long) at right angles to the wind. Plastic shrinkage cracks can allow water to enter an outdoor slab, where it may freeze, causing further deterioration.

    Under extremely hot, dry, and windy conditions, you may not be able to prevent crazing and plastic shrinkage cracks; it’s best to pour early in the day or wait until conditions improve. You can also use set retarders to slow hydration, and some batch plants may offer ice as a replacement for part of the mix water.

    Lower strength. Furthermore, excessive evaporation will lower the final strength of the slab, since hydration may not resume once moisture is again present. A slab that is not sealed with plastic or a curing compound must be kept continuously wet throughout the initial curing period if it is to achieve full strength.

    I call BullSh*t, What a scam, Thought they would have an open checkbook from the tribe. No money, no expertise and a scam artist. Make a couple of phone calls. These idiots have no intention of run a race. They pour thousands of yards of concrete everyday in the valley of the sun.
