"Officials say workers need an average of at least 40 degrees to effectively pour a new latex-modified concrete layer on road surfaces to treat cracks and leaks."
This misses the point. The real question isn't "when will it be done?" The real questions are: Is the latex concrete overlay needed? If so, why? Will it fix the problem? If not, then why not?
The SSTC is severely flawed; there is extensive cracking in supported slabs, beams, girders and columns, likely caused by the SSTC's complete lack of expansion joints. This is clear from KCE's report that was commissioned by Montgomery County and can be viewed and downloaded on Montgomery County's website. Standard construction practice requires expansion joints in structures exposed to temperature changes. WMATA design and construction standards, to which the SSTC was supposed to have been designed and constructed, require expansion joints to be located no more than 100 feet apart. The 315 ft. by 580 ft. SSTC has none. A concrete overlay will not fix the underlying problem--extensive cracking caused by the complete lack of expansion joints.
The questions at the end of the video are relevant: Is the SSTC safe? And, how much will it cost? Total costs include future operations and maintenance costs, which will be high according to WMATA, because of the SSTC's numerous design, construction and concrete inspection and testing flaws. Other costs include extras (above original design, inspection and construction contracts), repairs, outside engineering and legal fees, future court costs, and Montgomery County's administrative costs to-date and in the future.
