Can a high flow planer 40" model or thereabouts be used to mill limestone that protrudes from roads? Can the planer be used to crush rocks or tear up an existing base road before regrading and compaction? I've been looking for a solution to rehabilitate old ranch roads without having to bring in so much base that just washes away every time we have a 3 or 4" overnight rain. Now that the TX drought is easing, we have had two 48 hour periods with 4+ inches of rain in the last couple of months. At $200/load for base that's used on steep roads, I'm hoping to find an attachment that will allow me to work with some of what's already on these ranch roads. Any thoughts?
