Despite the higher capital costs of tunnels and supplementary cost maintenance, fewer deterioration models have been built compared with other highway components. Most these were limited to structural defects, not operational conditions. Moreover, there are inherent subjectivity inaccuracy developed models, which may affect maintenance process. The aim this research proposed contribution invest...
