Road Barriers : Temporary Barrier : ABSORB 350® Crash Cushion
 

1. Is the ABSORB 350™ a permanent or temporary crash cushion and where should it be used?

The ABSORB 350™ is a temporary crash cushion suited for TL2 and TL3 situations and attached to safety concrete barriers on flat metal or tar roads.

2. What type of equipment is needed to fill the modules with the water and antifreeze mix? If special equipment is needed, does that come with each unit?

No special equipment is required for filling the ABSORB 350 units. The hole in the top of the ABSORB 350 element is 75mm in diameter. A standard water truck with 62.5mm diameter hose is completely adequate for filling ABSORB 350 element

3. Does your company provide spare parts?

Yes spare parts are available and can be dispatched within 24 hours after acceptance of order.

4. Does your company teach installers to service and repair the ABSORB 350? On average, how long does this take?

Full training can be given to installers on how to service and repair the ABSORB 350 system. The time taken to do any repairs will depend on the severity and location.

5. Does your company provide a hire, maintenance and repair contract to service the ABSORB 350 units apart from just selling the units outright?

Yes, our hire department have several options available to choose which includes maintenance and or a buy back system.

6. What type of environmentally safe antifreeze does your company recommend? Are there any anti-freezes that are not compatible with the materials that the ABSORB 350 is made of?

These include:

  • Calcium Chloride (CaCl2) - a 25% by weight solution should yield protection to below -20º F.*
  • Calcium Magnesium Acetate (CMA) - a 32% by weight solution should yield protection down to -20º F.*
  • Potassium Acetate (KAc) - a 32% by weight solution should yield protection down to at least -20º F *
  • Above recommendations are from Cryotech Deicing Technology, Inc. Reference information can be obtained at the following website: http://www.cryotech.com
  • There are no known antifreeze agents that should affect the materials in the ABSORB 350 system.

7. Can the ABSORB 350 "nose piece" be angled off the concrete barrier to better face traffic?

The ABSORB 350 system is designed to be flexible to allow for "small angle adjustments" and movement at job site. The "nose piece" can be angled off to face traffic as long as all of the ABSORB 350 units remain pinned and fully connected. For larger angles, it is recommended that the last concrete section be moved to face traffic to reduce tension on the system.

8. How is the ABSORB 350 drained?

The ABSORB 350 system can be drained in minutes by following this easy process:

1) Uncap the 75mm fill hole located at the top of each unit,

2) Unpin the unit from adjacent units

One person with a pry bar can tip the unit on its side until it is partially drained and then rotate the unit upside down to be fully drained. Drainage can also be accomplished by using a water truck with vacuum or reversible pump capabilities.
