central - east central Minnesota - | jblands - 3/15/2024 23:00 The main question I have about geo is will it hold up with 60,000 pounds loads going over it. Somedays 70 or more trucks will load out during the summer.
As posted, yes, the CORRECT geo-textile fabric will work. As posted, it takes at least 8 inchs of rock on top to keep the fabric from "floating" and bubbling around. I would think the contractor would know what to use ? Here, it common to use screened sand two feet thick then geo-textile fabric with class 5 gravel on top of the fabric for the road base. That would be in some marshy soils - not too marshy to sink and float with water - but unstable and like in the old days when corduroy with logs was common, now fabric's are used . . . . . |
sand road needs reinforcement
