Surface Mount Versus Flush Mount Traffic Spike Strips
Traffic spikes are not a complicated safety and security system. There are a few types of traffic spike strips, with the two main differentiators between types being the mount and the operation. Traffic spike strips can be surface-mounted or flush-mounted, which is also referred to as in-ground, and then can be, in a sense, manual or motorized. Motorized traffic spikes are controlled by the gate opener system, retracting when a vehicle is authorized. There is plenty to discuss about motorized traffic spikes, but you came here to learn the difference between surface mount versus flush mount traffic spike strips, so let’s take a look.
Surface-Mounted Traffic Spike Strips
Surface-mount traffic spikes are installed on the surface of asphalt or concrete driveway using epoxy and anchor bolts. An additional feature of surface-mounted traffic spikes is its functionality as a speed bump. These traffic spikes can be spring-loaded or motorized and are generally seen with end bevels, which round off the edges of the strip, limiting possible, unintentional tire damage. Because these traffic spikes are installed on the roadway’s surface, so they do not have the same noise-dampening effect as an in-ground or flush-mounted traffic spike system.
Flush-Mounted Traffic Spike Strips
Flush-mount traffic spikes require that the roadway surface be trenched because the traffic spike system will be laid into the ground to be even, or flush, with the ground’s surface. Speed Bumps are a recommended addition to these traffic spikes to limit the speed of a vehicle before it crosses. These traffic spikes are available in three-foot and six-foot strips, rated for 15,000 lbs. and 40,000 lbs. per single axle load, respectively. This load rating is significant compared to the three-foot surface-mount traffic spikes, which have a capacity of 15,000 lbs. per single axle load. Flush-mount traffic spikes have superior sound-dampening as the ground absorbs the noise.
