The transverse cracks appeared to be in good shape. They were not wide and the spacing
seemed to be adequate. The few distress symptoms found consisted mainly of minor spalls.
There was a very long longitudinal crack that extended for a few tenths of a mile on the
westbound outside lane. However, this crack was narrow and despite its length, it did not seem to
be associated with any additional distress. The eastbound section also showed some asphalt
patches, but mainly the patches were concrete. There was a particularly long PCC patch that
extended for about 45 ft. on the eastbound inside lane. Table 3.3 summarizes the results in the
westbound section, and Table 3.4 presents the eastbound results.
In summary, the overlay was in excellent condition. The few spalls that were present,
mainly in the westbound section, were all minor. Even though there are a handful of distress
symptoms, none of them appeared to be severe. No punchouts were observed. Photographs from
the survey are presented in Appendix A-2.
