Imagine a drive to grandma's house or to work with fewer "left lane closed ahead" signs, fewer detour signs, fewer orange barrels and also safer travel near road crews. That may soon be possible with new technology from Purdue University researchers.
...
This technology uses electrical resistance measurements to determine when the emulsified asphalt in a chip seal has sufficiently cured and can therefore withstand traffic without sustaining damage. Such real-time measurements help ensure that the road repairs are done correctly and more quickly than using current methods.

"Typical approaches to quantify emulsified asphalt-based chip seal curing times are varied and qualitative," said John Haddock, a professor of civil engineering and the director of the Indiana Local Technical Assistance Program, who leads the research team. "Having a quantitative, real-time measurement method can help construction crews make good decisions that result in a quality chip seal project with minimal traffic disruption."

The engineers will know exactly when the asphalt can be driven on.

    > even concrete, is vastly superior to asphalt

    That's nice, except asphalt is concrete. Or more specifically, what is generally called asphalt is really asphalt concrete, a specific blend of concrete which contains asphalt/bitumen designed specifically for road paving. Like all concrete, they need to be carefully mixed and cured for maximum strength; this is probably where most of the durability issues come from.
