The survey on SH 146 was conducted. The BCO is located in Harris County in Baytown,
and its limits are from the Chambers County line to North Main St., for an approximate length of
4.5 mi. The overlay consists of a 3-in.-thick BCO on top of the existing 11-in.-thick CRCP. This
BCO was designed in 1998, and it was constructed in the early 2000s.
3.6.1 SH 146 Survey
The survey consisted of a visual inspection of the outside lane of the BCO, observing the
cracks and distress, and photographing some of the more interesting. Because the road was open
for traffic, it was not possible to conduct this survey in more detail. The survey was conducted
while driving at a very low speed in the outside traffic lane, while a cushion truck and a shadow
vehicle, provided by the district, moved along behind the survey vehicle for protection. During
part of the survey, there was rain, which made it hard to see the pavement at times. The rain was
particularly intense during the survey of the southbound lanes; therefore, the level of detail of
this part of the survey was not optimal. The survey started with the northbound sections, from
North Main St. to the Chambers Co. line, and then the southbound sections followed.
The distresses consisted mainly of punchouts and minor spalls. There was a number of
punchouts at the south end of the section in the southbound lanes, where the pavement showed a
limited number of cracks, but some distresses had been repaired and were failing again. There
were also some sections in very good condition without many cracks or distresses. Table 3.1
shows the results of the northbound sections, and Table 3.2 presents the southbound sections.
As mentioned before, some segments on the southbound side could not be surveyed
thoroughly because of the rain, but the overall assessment of those is shown in the comments
column in the tables. Some of these segments did not show any distress or damaged cracks.
In summary, with the exception of a few segments that are badly deteriorated, some
showing severe failures, the overlay is in good condition. Photographs from the survey are
presented in Appendix A-1.
