Abstract :
This paper introduces a degradation-path model for utility wood pole asset management that facilitates estimation of failure probability and time to failure, indicators which are useful in maintenance decisions. This model requires degradation data, which for wood poles are measurements of the residual strength around the ground line. Non-destructive measurement methods of the residual strength are well developed and enable application of this model. The method is illustrated using actual measurement records.
