Project Background: Problem

Roadside weighing guidelines (Austroads 2005) only deal with conventional heavy vehicles, not Oversize Overmass (OSOM) combinations

See Section 1

1313

Project Background: Aim

To produce:

• Guidelines for assessing mass of OSOM vehicles at the roadside

• Mass Measurement Adjustment (MMA) figures and calculation processes

See Section 1

1414

Project Background: Scope

• Organise and conduct field trial, weighing a set of four vehicles at a roadside inspection site

• Analyse data

• Determine MMA

• Develop guidelines for weighing and use of the MMA

See Section 1

Test site

Weigh site category specifications

• Category 1 is the flattest and includes weighbridges

• Category 2 is steeper, with more crossfall allowed

• Category 3 is steeper and has no crossfall limit

See Section 5.1

Weighing category Longitudinal gradient Transverse gradient Unevenness (mm)

Category 1 2% (up to 100 mm) 3% (up to 105 mm) 10

Category 2 3% (up to 150 mm) 5% (up to 175 mm) 20

Category 3 5% (up to 250 mm) No limit (up to 175 mm) 50

Testing – The Weighing ManoeuvresPhilip Roper

2626

Field tests

Staged weighing using scales and blocks

• Fully blocked weighing raises allaxles onto either scales or blocksof scale height

• Partially blocked weighing raisesall axles of one vehicle unit(e.g. prime mover or a trailer)

• Unblocked weighing raises only the axles that areon scales. Unblocked A weighs one axle at a time,Unblocked B weighs two axles at a time.

See Section 6.2

Recap

• OSOM vehicles can be weighed accurately

• Several moves will be needed to weigh a complete vehicle

• Measurements adjusted by tonnes or percentages, depending on what is weighed
