Pre-emptive crack sealing?
Pre-emptive crack sealing?
(OP)
Our department commissioner and I were driving down a road freshly resurfaced with HMA, and he saw a noticeable cold joint down the centerline.
He wondered, what would happen if we crack-sealed the new joint now, rather than when it started to open up a few years from now? Could we prevent or delay later deterioration now, rather than reacting to it later? Would it be cost-effective?
Has anyone ever seen any research on the topic? Would it be worth doing an experiment with a few test and control sections?
Just curious.

RE: Pre-emptive crack sealing?
For conventional crown, it is debatable, but if there is a distinct joint separation, I would seal it.
Yes, it is worth doing a little study...formal or informal.
