What does HS20 44 mean?
Example of an HS truck loading: HS20-44 indicates a vehicle with a front tractor axle weighing 4 tons, a rear tractor axle weighing 16 tons, and a semi- trailer axle weighing 16 tons. The H and HS vehicles do not represent actual vehicles, but can be considered as “umbrella” loads.
What is the rear axle load for hs15 44 vehicle?

What is Aashto H-20 loading?
32,000 pounds
H-20 loading, also known as HS-20 loading, is the design criteria of the American Association of State Highway Transportation Officials, or AASHTO. It “means” a truck axle loading of 32,000 pounds or wheel loading of 16,000 pounds. Standards as published by AASHTO are categorized into classes.
What is H20 rating?
The Silva Cell can support vehicle loading up to AASHTO H-20 rating of 32,000 lbs. (14,500 kgs) per axle. This rating refers to the ability of a roadway to safely accommodate 3-4 axle vehicles, such as a large semi-truck and trailer.
What does load capacity H25 mean?
H25/HS25 = 20,000-lb wheel load, 40,000-lb axle. Covers designed to meet the basic requirements for these loads need only be tested with a proof load to meet these minimums. If a specification requires H20/HS20 loading it simply requires a cover meet the design load of 16,000 pounds per wheel without a safety factor.
How much weight will my bridge hold?
In addition to Bridge Formula weight limits, Federal law states that single axles are limited to 20,000 pounds, and axles spaced more than 40 inches and not more than 96 inches apart (tandem axles) are limited to 34,000 pounds. Gross vehicle weight is limited to 80,000 pounds (23 U.S.C. 127).
What is Aashto LRFD?
The AASHTO LRFD Bridge Design Specifications are intended for use in the design, evaluation, and rehabilitation of bridges. The specifications employ the Load and Resistance Factor Design (LRFD) methodology, using factors developed from current statistical knowledge of loads and structural performance.
What is a H25 load capacity?
What’s the difference between hs-25 and hs20-44?
RE: Asshto Loads – Difference between HS-25 and HS20-44? HS25 is a 45T truck with the same axle configuration as HS-20. It came about 20 or so years ago to address the presence of heavier trucks and tandem vehicles. The decision to use HS-25 or HS-20 is up to the bridge owner.
What’s the difference between HL-93 and hs-25?
Essentially, they are the same loading except HL-93 requires the lane load to be applied simultaneously with the truck load. A simple internet search can find the size of the truck and weight of the axles, or in the LRFD Specification. RE: Asshto Loads – Difference between HS-25 and HS20-44?
