PRODUCT DESCRIPTION 

(i' New Hardware or 

Significant Modification 

(' Modification to 

Existing Hardware 

The ABSORB-MTM is a non-redirective, gating crash cushion designed to meet the latest test standards defined 

in the Manual for Assessing Safety Hardware (MASH), Second Edition, 2016. The ABSORB-M system utilizes 

water, thermoplastic elements (elements), tension straps, a midnose, and a transition to absorb kinetic energy 

and safely contain or control the trajectory of impacting vehicles. The MASH Test Level 3 system is comprised 

of a nose plate, three elements, ten pin assemblies, a midnose, a transition, and six mechanical anchors 

attaching to the barrier system. Of the three elements, the middle and rearmost are filled with water and the 

front element is empty. Each element is pre-assembled using four tension straps secured with eight bolts and 

thread locking compound. The system has a nominal 42" [1070mm] height, 24" [600mm] width, and an 

effective length of approximately 251 3/4" [6.4ml. The ABSORB-M is designed to attach directly to longitudinal 

roadside safety barrier systems and does not attach to a foundation. 

More details about the ABSORB-Mare provided in Enclosure A titled "ABSORB-M MASH TL-3 Crash Cushion 

System". 

Manufacturing drawings may be adjusted to ensure manufacturing capability and consistency with MASH 

tested and certified product.

Results 

The ABSORB-M was determined to have 

successfully met all of the evaluation criteria 

for MASH Test 3-40 for gating, nonredirective crash cushions. 

The ABSORB-M crash cushion satisfied the 

MASH structural adequacy criteria for its 

intended function as a gating, nonredirective crash cushion. The test article 

captured the 11 00C vehicle in a controlled 

manner. The vehicle did not penetrate, 

underride, or override the installation. 

All of the occupant risk criteria were 

satisfied in testing the ABSORB-M crash 

cushion. Theoretical OIVs in the longitudinal 

and lateral directions were below the limit 

of 40.0 ft/s (12.2 mis). ORAs in the 3-40 ( 11 00C) longitudinal and lateral directions were 

below the preferred limit of 15.0 G. Some 

debris were propelled from the impacted 

system but due to their soft nature and light 

weight these fragments did not pose a 

threat to occupants of the vehicle, 

pedestrians or personnel in a work zone. 

There was minimal deformation to the 

occupant compartment of the 1lO0C test 

vehicle. There was no intrusion into the 

occupant compartment. The test vehicle 

remained upright during and after the 

collision with minor roll and pitch. 

The ABSORB-M crash cushion was judged 

as satisfying the applicable MASH vehicle 

trajectory criteria.

INTENDED USE 

The ABSORB-MTM is a non-redirective, gating crash cushion designed to meet the latest test 

standards defined in the Manual for Assessing Safety Hardware (MASH), Second Edition, 2016. 

The ABSORB-M system utilizes water, thermoplastic elements (elements), tension straps, a 

midnose, and a transition to absorb kinetic energy and safely contain or control the trajectory of 

.impacting vehicles. The MASH Test Level 3 system is comprised of a nose plate, three elements, 

ten pin assemblies, a midnose, a transition, and six mechanical anchors attaching to the barrier 

system. Of the three elements, the middle and rearmost are filled with water and the front element 

is empty. Each element is pre-assembled using four tension straps secured with eight bolts and 

thread locking compound. The system has a nominal 42" [1070mm] height, 24" [610mm] width, 

and an effective length of approximately 251 3/4" [6.39m]. The ABSORB-Mis designed to attach 

directly to longitudinal roadside safety barrier systems and does not attach to a foundation. 

APPROVALS 

The ABSORB-M TM system has been fully tested in conformance with MASH, 2016 Test Level 3 

and is determined eligible for Federal reimbursement by FHW A.

ABSORB-WM Anti-Freeze Solutions 

In regions where the water filled ABSORB-MTM elements could become frozen, proper antifreeze 

agents should be used. Care should be taken to ensure that proper antifreeze agents are used in 

accordance with local regulations, environmental concerns and ensuring that any post impact liquid on 

the road surface does not constitute an undue hazard to adjacent motorists. 

The infonnation outlined in this document is intended to provide a general guide to ABSORB-MTM 

users for choosing, ca lculating, and applying anti-freeze solutions. The actual method and 

implementation of an anti-freezing solution should be detem1ined by state and local standards and in 

accordance with the spec ific manufacturers' instmctions. 

Possible Anti-Freeze compounds include: 

• Calcium Chlo1;de, CaCh 

• Calcium Magnesium Acetate, CMA 

• Magnesium Chloride, MgCh 

• Sodium Chloride, NaCl 

• Potassium Acetate, KAc 

Considerations for choosing an Anti-Freeze should include enviromnental impact on local vegetation 

and waterways, coITosion of existing stmctures, and the effect on concrete or asphalt roadways. 

Transportation, installation, and handling of the material should also be considered. TI1e examples 

listed above are products commonly used on highways as de-icing road and bridge conditioners and for 

dust control. Spec ific infom1ation pertaining to these products regarding said considerations should 

be readily available from the product supplier or manufacturer. 

The coJTect mixture of Anti-Freeze and water is critical to insure proper ice protection and 

perfonnance of the ABSORB-MTM crash cushion. TI1e freezing capacity depends on the particular 

chemical and the solution concentrate by percent weight of the solution. Both too little and too much 

solution will result in diminished freezing capacity. The ideal solution concentration for maximum 

capacity is specifi c to the chemical chosen. It may be desirable to reduce the concentration for cost 

savings if the maximum capacity is not necessary. 

Depending on the fonn the chemical is provided; such as a fluid, powder, or pellet; the actual amount 

ofthe desired chemical may not constitute l 00 % of the material by weight. It is important to account 

for the actual weight of the deicing chemical when mixing the solution.

A typical solution recommended by some customers is Calcium Chloride. 'The ideal solution fo r 

maximum capacity is 29% by weight Calcium Chloride providing a freez ing temperature of -53°1; (-

470C). This solution is commonly used as a road-deicing agent, thus satisfying particular 

environmental regulations. It is available as a fluid solution of definite concentration or pellets and 

flakes in various sized bags. If purchased in fl ake. or pellet fonn, care must be taken in dissolving it in 

water. Also, the concentrate must be calculated from the actual Calcium Chloride content. For 

example, if the flake/pellet agent purchased has a Calcium Chloride content of 80% and a 29% 

solution by weight is desired, the quantity added must account for the impurity of the agent. TI1ese 

principles apply to many various anti-freezing chemicals. Refer to the manufacturer or supplier for 

how to calculate the quantity of agent to add to the ABSORB-MTM element based on the actual 

chemical and agent used, given the ABSORB-MTM Data shown below. 

ABSORB-Mm Data 3 Fluid Capacity of (1) ABSORB-MTM Element: 250 Gallons (947 Liters), 33.4 ft' (.947 m ) 

Weight of Water at 30° F (0° C): 62.4 lb/ft3 (999.6 kg/m3

) "" 2086 lb (947 kg) H20/Element
