拖车式颠簸累积仪
Rural road programmes with modest budgets often still rely on response-type measurement. This single-wheel trailer is towed at a constant 32 km/h and integrates suspension movement in 1 mm counts, reporting roughness from 500 to 10,000 mm/km. Output must be correlated to IRI on calibration sections, and the in-cab counter stores each run.
