Overview

smart ROMEN CATCHER LY Jr. is a road surface condition survey vehicle that passed the performance test for automatic road surface condition measuring equipment and is capable of safely implementing surveys even on narrow roads.

Features

  • Simultaneous acquisition of vertical direction acceleration, road crack imaging, and cross section profile by the survey vehicle
  • Recording of photographs
  • The road surface condition is evaluated indoors using the acquired data
1.Longitudinal irregularities (IRI: International Roughness Index):Visual evaluation of IRI from the vertical acceleration standard deviation and the images.
2. Rutting:Evaluation complying with the “Method using a road surface condition measuring vehicle” described in the “Pavement Surveying and Testing Handbook”.
3. Road cracks:Evaluation complying with the “Method using a road surface condition measuring vehicle” described in the “Pavement Surveying and Testing Handbook”.
4. No. of patches:Counting of the number of patches in the section being evaluated from the images.
