Abstract:

For distress surveys of asphalt pavements, the automated results from two vendors compared reasonably closely in ratings to the manual methods. In addition, automated ratings for jointed concrete pavement show much greater inconsistency between different distress types than for asphalt or continuously reinforced concrete pavement types.

For the rut depth comparison, one vendor had more accurate rut depth measurements than the other based on the reference measurements obtained by the research team.

What This Means

Based on this research, it appears that TxDOT should be able to procure a pavement condition data collection service provider that can provide data comparable to traditional manual methods.

The contract language developed under this study has already been implemented as part of the request for proposals issued by TxDOT on July 18, 2016. In addition, TxDOT personnel plan to use the performance specification when auditing data from the service provider.
