Designated Parking Corp.
Designated Parking Corp. ("DPC") is a United States corporation specializing in the design, manufacture and marketing of single-space parking barriers and asphalt anchors. The company was formed in 2002 with the specific purpose of developing energy-efficient low cost barriers and gates.
The company's engineering center is located in a suburb of New York City. Manufacturing is done mostly in China, by an affiliated company with 2,500 employees. Sales are carried out through a network of independent distributors in 40 countries. A group within the company develops and market asphalt anchors under the Asphalt Anchors Group name. A separate web site provides full information about that product line.
The founders of DPC bring their extensive experience in the development, manufacturing and marketing of garage doors, alarm and security systems, consumer and automotive electronics.
Introducing the MySpot™ 500 Parking Barrier
MySpot™ 500 is a low cost, self-contained, remote controlled barrier. The system is battery powered and restricts unauthorized access to parking spaces, driveways and access ramps, while providing the convenience of remote control to authorized vehicles. MySpot 500 is our latest product offering. Designed from the ground up, it incorporates the latest technology in battery power management, motor power control and software to offer 2-3 years of operation without replacing the internal alkaline batteries. This eliminates the need to connect the device to an electrical power source, or the bulk and cost of batteries with solar panel recharging. The unit is supplied with 2 remote control fobs and hardware for installation to masonry surfaces. Installation kits for asphalt surfaces are available (AK4).
Installation is simple and fast – no digging or site preparation is required. The unit is shipped pre-assembled in one piece. Drill 4 holes in the surface and attach the unit and the MS500 is ready for use.
The MS500 is currently available and the list price has been set at $460 FOB NJ.
Asphalt Anchors 101
in order to mount to asphalt, one can not use any device or method that applies a constant pressure to the asphalt. Examples of anchors that can not, under any circumstances, be used on asphalt are expansion or wedge anchors. Wedge anchors are a low cost and very effective method of anchoring to concrete. The anchor expands inside the hole in the concrete as the attaching bolt is tightened. The sideways pressure on the walls of the hole jams the body of the anchor in the hole and keeps the anchor embedded in the material.
The continuos ("static”) pressure exerted on the asphalt walls by the wedge anchors will cause the asphalt to flow, and the anchors will loosen and lose its grip. Wedge anchors can tolerate no "give” from the substrate in which they are installed. There is no spring action involved — the anchor is expanded to the initial dimensions of the hole, and if the hole becomes larger, the anchor will no longer be jammed in the hole. Thus in asphalt, the wedge anchors will lose their grip in a very short period of time (hours or a few days).
How Asphalt Anchors Work
All anchors that are qualified for use in asphalt are classified as "chemical anchors”. In essence they use a grout to bond the anchor to the asphalt. The term "grout”is used generically, and can include epoxy, resins and cement products.
Installation procedures vary with the manufacturer,but follow essentially a similar pattern. To install the BoltHold™ anchors manufacturers by asphalt anchors.com, an oversize hole is drilled in the asphalt. The hole is filled with grout, and the anchor is pushed in until it is flush with the surface. The displaced grout is pushed into the crevices in the asphalt and in the gravel layer below to create a strong bond with the asphalt.
The selection of the grout is quite critical. Among the key considerations is whether the grout shrinks during curing, curing time, range of ambient temperatures when the grout can be installed, grout hardness, adhesion to the anchor and water resistance.
Asphalt Anchors are a Reliable Economic Solution
Properly sized and installed, asphalt anchors have proven their reliability over thousands of demanding applications. Anchors manufactured by Toge in Germany have been certified for the installation of crash barriers on German highways. BoltHold anchors have been used to secure plane arresting traps designed to bring planes to a top if they overrun the runway and heavy equipment and shelves against earthquakes in Hawaii.These anchors allow installation directly into asphalt, without the intermediate steps of removal of patches of asphalt, pouring of concrete, waiting 24 house for the concrete to cure, then returning, drilling and installing wedge anchors.
Anchors Help Stop Runaway Airliners
Midway airport in Chicago has short runways. It has been the scene of a deadly overrun in 2005, and last year installed an airplane arresting system. The system can bring an airplane to a stop from 80 miles per hour.
The sketch above, courtesy of the Chicago Tribune, shows the key element in the system — the Arrester bed. The bed is comprised of light weigh glass rocks, which crumble to absorb the planes energy. The rocks need to be kept in place even under jet blasts from planes taking off from that runway.
The design called for a metal grid to contain the rocks. BoltHold SP10 anchors were selected to secure the grid to the runway after confirming their pull characteristics met or exceeded the manufacturer’s rating (see graph in article). About 4,000 anchors were used.
Since arrestor beds were first installed in the US, they proved their worth in 9 incidents involving 243 passengers and crew members according to a Chicago Tribune article. Previous arrestors suffered from damage from jet air blasts, which this new generation of arrestors is expected to overcome.
The graph below plots the pull force vs. time when a BoltHold SP10 anchor was pulled out of a 3-4” asphalt runway in Midway airport in Chicago (see sidebar story). The force is gradually increased until about 6,000 lb., at which point the force drop indicates that the anchor started to pull out, followed a second later by a major movement in the anchor which was no longer able to resist the pull force. It is noteworthy that the SP10, which is rated for 1,500 lb. pull, withstood 6,000 lb.
