Reply to comment by Spinaccio in Researchers have developed new “intelligent compaction” technology, which integrates into a road roller and can assess in real-time the quality of road base compaction. Improved road construction can reduce potholes and maintenance costs, and lead to safer, more resilient roads by giuliomagnifico

What's the use in predicting a fail point in the road base gravel when you pave in June, and then the seasons, weather, temperature, ground water, frost level, humidity, traffic variations and countless other variables come into play?

With this tech you might be able to prevent 0.01% of deficiencies.

Don’t know where you get 0.01%. Current QC requirements in the US that I work with call for roll testing, visually observing a heavy object rolling over the substrate, hoping to see any soft spots in the substrate, and Nuclear densitometer testing which is highly localized and in my experience used to show an average compaction over an area. Adding testing that is more widespread, even without 100% accuracy, gives quality control an additional tool to find soft spots in a roadbed before it is paved over.
