Presentation Transcript

  1. Road and airfield surface characteristics – Test methods- Measurement of transverse and longitudinal profiles in the eveness and megatexture wavelength ranges • CEN/TC 227 ”Road materials” • Forslag / proposal • Longitudinal: ujevnhet (IRI) • Transverse: spordybde

  2. Krav til utstyr Langsgående (longitudinal profiling) • Distansenøyaktighet • Vertikal oppløsning/nøyaktighet • Data sampling intervall • Rapport sampling intervall • ”Cut-off” ved store bølgelengder

  3. Krav til utstyrTverrprofil (transverse profiling) • Vertikal oppløsning/nøyaktighet • Data sampling intervall i tverrprofil • Data sampling repetisjon • Rapport sampling intervall • Tverrfall / lutning

  4. 3 klasser - eksempel • Vertikal oppløsning/nøyaktighet - langsgående måling: • Class 1: mindre enn eller lik 0.2 mm • Class 2: mellom 0.2 mm og 0.5 mm • Class 3: mellom 0.5 mm og 1.5 mm • Data sampling intervall - langsgående måling • Class 1: mindre enn eller lik 50 mm • Class 2: mellom 50 mm og 125 mm • Class 3: mellom 125 mm og 250 mm

  5. Detaljerte krav til • Utførelse i felten • Kalibrering • Feilsjekking • Vedlikehold • Rapportering • Administrativ • Teknisk
