One combination of factors that contributes to potholes and side-of-the-pavement erosion is the high rainfall and how it fills up small lava tubes that then bubble up to the surface.
When the roads for OLE were first plotted out ( by someone sitting at desk in Honolulu ), they neglected to factor in that there is an intermittent stream that rises at the intersection of Auli'i and 40th when it is raining very hard in what is now Hawaiian Acres, Fern Acres, etc. There were times when we joked about taking a kayak down the resulting rapids. Further down the hill, before any of Auli'i was paved, large puddles and potholes would consistently appear in specific spots, again because lava tubes close to the surface filled up and spilled over. This is where we now deal with huge pot holes in the chip seal. On what used to be the edge of an a'a flow between 39th and 40th, ( again on Auli'i ) the sun can be out overhead, but if the clouds are letting loose higher up the hill, small rivulets of water can be flowing down, and eating away at the edges of the asphalt.
I know that each subdivision has different terrain and rainfall, so what I've described above will not be relevant to all, but I wanted to bring up some of the unique factors that create problems and put us at or near the top of of these surveys.
