(1) So, does concrete make financial sense over 20 years or so? 50 years? Never in a (existing) MHP?
(2) How to “redo” asphalt roads most long-term cost-effectively? What should I be asking for? Sections or complete overlay or what? I’ve seen this done poorly at many parks I’ve visited (usually overlay fails in the same spot the original was failing, only now you have to dig up twice as much to fix the sewer). Pure overlay does not seem to be right. I want to do it “right” so that it lasts and does not fail in the same way existing roads fail.
I would say the problem now is it’s a lot of potholes in some areas, and crumbling / shifting soil in other areas leading to fracture of the surface layer of asphalt, which kicks up stones which grind down the rest of the road; uneven road surface makes water collect in some areas which accelerates wear-and-tear (and turn to ice and heave, etc.) Need to think about drainage; if I’m going to solve this “right” one little bit at a time, where do I start? I can do calculations (get bids) by square footage but what do I want to put in “per square foot” to make sure that I’m doing the best (most long-term cost-effective) thing? releveling surface and fixing any subsidence would presumably be needed for larger patches (say, 30 feet by 100 feet) along with drainage? Yes no?
I have a lot of experience in some things, but this is something that surely others know much better than me! Help me out!
