Roughness Measurement
bull Present Serviceability Rating (PSR)ndash Based on ride quality defined by observerndash Values from 1-5
bull International Roughness Indexndash Based on Average Rectified Slope (ARS)
determined from vehicle accumulated suspension motion divided by the distance mkm
ndash IRI= 1000ARS018( )5 IRIPSR e
Dipstick Analyzerbull Operation
The Dipstick Road Profiler stands on two support legs
The operator simply walks the Dipstick along a survey line alternately pivoting the instrument about each leg
Two digital displays show the elevation difference between the Dipsticks two support legs
Audible and visual signals alert the operator when each elevation difference reading is measured and automatically recorded
