zero air void curve for soils zero air void curve for soils Pipe Guy (Civil/Environmental) (OP) 20 Nov 17 06:27 Does anyone know of a phone app for calculating the points on a zero air voids curve? RE: zero air void curve for soils Okiryu (Civil/Environmental) 20 Nov 17 21:38 I don’t know if an app is available but I would print out the proctor curve and plot those points manually or in EXCEL. Why do you need the app? For using it at the field? RE: zero air void curve for soils Pipe Guy (Civil/Environmental) (OP) 20 Nov 17 22:55 I sometime train earthwork inspectors. Everything will be done by phone in future. So I was looking for something for them to check if they get percent compaction results. So the lab could send the inspector not just the percent compaction but also the dry density and moisture content so they could see if the test result is reasonable. RE: zero air void curve for soils Okiryu (Civil/Environmental) 21 Nov 17 02:10 Apps are nice, but for this, I would just use a hard copy of the proctor curves and check where the information provided by the lab fits in that plot... RE: zero air void curve for soils fattdad (Geotechnical) 27 Nov 17 16:48 guess the specific gravity. Beyond that it's a closed solution and has nothing to do with the Proctor value! f-d ípapß gordo ainÆt no madre flaca! RE: zero air void curve for soils BigH (Geotechnical) 29 Nov 17 12:27 I give the contractor's staff doing the tests a laminated graph showing the ZAV. Whether you use 2.64 or 2.66 - doesn't make much difference - but bloody make sure the field tests results lie to the left of the line.
