Webb22 okt. 2024 · We calculate the maximum dry density of soil in the laboratory using standard proctor or modified proctor density tests on the collected soil samples from the site. The soil so compacted on the site should at least reach 95% of its maximum dry density, which we have calculated in the laboratory, using either of these methods. WebbThe One Point Spreadsheet will calculate a field one point result using the Maximum Wet Density / Speedy Moisture method, a standard proctor and a modified proctor using the ASTM or AASHTO method (s), or any combination of the three. Currently your field examinations are accurate to about 80 - 85% due to operator error.
