Solutions
3/3/20158 Ministry of Road Transport and Highways
ACROW BRIDGE SYSTEMS ARE:
•Pre-engineered, modular, and prefabricated
•Used for permanent and temporary applications
•No field welding or fabrication
•Supporting light pedestrian loads or vehicular loads such as IRC – 70R or trucks exceeding 250 tonnes or trains with 40 tonne axles
•Rapidly deployed and assembled very quickly
•Versatility that allows for assembly in any length or width, and any load combination
•Good economy when supporting 70R loads
•30% to 40% greater economy when supporting lighter loads such as 30R trucks and tanks and pedestrian loads of 3 kN/m2.

Comparison of Acrow Bridges to Concrete Bridges
3/3/201513
• Life span of bridge -- The life span of any bridge is driven by the average daily truck traffic (ADTT). Acrow Bridges
are designed to comply with an owner’s fatigue life specifications, whether that life is a long 75 years or a short 15 years. Roadway decks are the most fatigued and vulnerable part of a bridge, and typically are designed for shorter
life spans. It is not uncommon to replace or refurbish permanent concrete road decks every 5 to 15 years.
• Maintenance -- The Acrow Bridge once constructed requires almost no maintenance. No parts need lubricating. All
of the bridge is hot dipped galvanized and does not require future painting. Bi-yearly inspections are a good
practice. Theft and sabotage can be abated.
• Riding comfort -- Acrow decks do not loosen and provide a high quality driving experience on our factory applied
aggregate epoxy surface. An owner can also specify the use of hot mix asphalt as the driving surface.
• Use of local materials -- The local materials would be used in the piers and abutments. Otherwise, it is use of local
labor to assemble and construct the Acrow Bridge spans.
• Construction time -- Acrow finished building a 1.46 kilometer long bridge in Chile. Along with constructing the piers,
the entire bridge was shipped and constructed with approach roads in 80 days. There is no comparison on the
issue of time. A concrete bridge like the one described will take 2 to 3 years.
• Ease of construction -- Again no comparison. The ease of construction with an Acrow Bridge is exponentially better
than alternatives due to the simplicity that is a result of the prefabricated and modular design.
• Quality control -- Again no comparison. Acrow’s QC is tightly controlled in a factory environment with three Quality Assurance systems that were listed in the previous slide. However, the pre-stressed concrete beams and the
strength of the beams are highly impacted by the amount of water used in the mix, the chemistry of the water, the
types of aggregate used in the mix, the type of cement, the humidity of the air, the quality of the reinforcement steel,
the quality of the steel wire strands, the amount of tension applied to the steel wire strands, and other factors. If a
little too much water or too much sand is used in the concrete, the strength of a beam will be compromised.
• Design -- The Acrow Bridge is fully pre-designed with the design built into the price. A concrete bridge price likely
does not include the design price.

Comparison of Acrow Bridges to Bailey Bridges
3/3/201514
• A minimum of 25% lighter, which results in lower purchase price
• Significantly stronger in bending and shear – longer clear spans > 85m
• Many less parts. Lighter weight per a given span
• Less parts and lighter weight results in faster assembly
• Assembly of 30m span by 20 personnel in 7 hours
• Hot dipped Galvanized to resist weathering – little to no maintenance costs
• Lower assembly costs, and operating costs
• Made in factory certified annually to ISO9001, AISC Advance Bridge, and CE Quality Systems
• Modern steel deck with safe high friction anti-skid aggregate road surface
• Modern high strength steels of 450 and 350
• Much greater load capacities – Very heavy loadings, MLC120, Cooper and Euro railway, mining trucks to 300 tons
• Permanent or temporary use
