PACARA-COPA, M.; ROCHA, J. H. A.  y  LEDEZMA-PEREZ, J. S.. Time variability analysis for damage detection in flexible pavement using infrared thermography. Rev. ALCONPAT [online]. 2020, vol.10, n.3, pp.350-363.  Epub 06-Jun-2022. ISSN 2007-6835.  https://doi.org/10.21041/ra.v10i3.468.

This document discusses the time range to optimize and understand infrared thermography results when used on damage detection for flexible pavement. A monitoring activity was performed during 14 continuous hours (5:00 a.m. to 7:00 p.m.) for four study areas in a centrally located avenue in Cochabamba City, Bolivia. This activity evidenced an effective time range to take thermographic images from 11:00 a.m. to 4:00 p.m. Damage visualization by differential colorimetry in thermograms at different times was also verified. This test enables locating areas where a detailed inspection may be performed. As a limitation, its sensibility to changes under environmental conditions is evident.

Palabras llave : infrared thermography; flexible pavement; inspection.
