Figure 3.1. Layout of IH-610 North experimental sections
In November 2000, a condition survey was conducted as part of another TxDOT research
project. That survey [50] demonstrated that the BCO performance had been excellent after 15
years of traffic. In spite of the fact that th te sounding tests performed back in 1987 showed some
delaminations soon after the overlay was placed, the 2000 survey showed that those
delaminations had not turned into punchouts, indicating the good performance of the BCO up to
that point. The number of distress issues was minimal, most of which were minor spalls.
3.8.2 Condition Survey
The 2009 survey consisted of a detailed visual inspection of the experimental sections.
Transverse cracks were counted, as well as distresses and patches. The results are summarized,
by section, in Table 3.6, and photographs of the survey are included in Appendix A-3.

The results indicate that eight of the ten experimental sections are still in very good
condition, while the remaining two, namely sections 4 and 5, look much more deteriorated.35
