I've found filling in pot holes with 1-1/2" drain rock to be the most effective way to keep them from coming back. The larger rock doesn't wash out or get pushed out by cars driving fast. It's a little rougher ride over the filled holes, but way better than pot holes.
So it sounds like you've found base coarse to be a good band aid fix for potholes. You're right, a side effect of base coarse is dust, a 2nd reason base coarse shouldn't be used for road material. Consider riding on a mile of road w/that material, and consider if this was laid on all the unpaved cross roads in HPP. It would be even worse for pedestrians and bikes. Someone on my road tried cement to fill a pothole.
Something similar if not the same as base coarse, was laid on some DE roads of Makuu back in early 2014. Angry lot owners from one of those roads got a petition together demanding the GM scrape that "crap" off the road and lay down good road material. They were so angry they were demanding the GM's and board Pres's resignation. The crew pretty much removed it but before the job could get finished, the GM was fired. One of those lot owners showed up at the recent mtg politely requesting the board fulfill the request. The GM told him he has a lot of work orders and the lot owner's time would come soon. They were over budget on road material. (But coming sooner is more CS roads?)
After discussion w/an Oahu friend a few yrs ago, (an international geological engineer consultant, UH professor, and author of university text book, "Soil Improvement and Ground Modifications Methods) and his checking out what was on our roads, said that it's best to pay more up front for good road material as it will last a lot longer. That what we had on our roads was good under asphalt or in the garden...it was not "road material". Going cheap, or using bad quality road material will end up wasting money instead of saving money. He suggested getting proctor tests as part of our routine road material purchasing process.
May be time to revive the Road Committee who was on the brink of doing test roads w/diff combos of road material in 2014, before the employee firings. The board that followed and in control of our roads for 3 yrs now had no interest in continuing that committee. Look where we are today. We've gone backwards, not forward.
