City of Ramsey <br />Project B1705491 <br />August 11, 2017 <br />Page 13 <br />D.3.d. Cold Weather Precautions <br />If site grading and construction is anticipated during cold weather, all snow and ice should be removed <br />from cut and fill areas prior to additional grading. No fill should be placed on frozen subgrades. No frozen <br />soils should be used as fill. <br />Concrete delivered to the site should meet the L,,,N" Gture requirements of ASTM C 94. Concrete <br />should not be placed on frozen subgrades. Concrete should be protected from freezing until the <br />necessary strength is attained. <br />E. Prch.k.wui t� <br />E.1. Penetration Test Borings <br />The penetration test borings were drilled with a truck -mounted core and auger drill equipped with <br />hollow -stem auger. The borings were performed in accordance with ASTM D 1586. Penetration test <br />samples were taken at 2 1/2 foot intervals. <br />E.2. Material Classification and Testing <br />E.2.a. Visual and Manual Classification <br />The geologic materials encountered were visually and manually classified in accordance with ASTM <br />Standard Practice D 2488. A chart explaining the classification system is attached. Samples were placed in <br />jars or bags and returned to our facility for review and storage. <br />E.2.b. Laboratory Testing <br />The results of the laboratory tests performed on geologic material samples are noted on the appi up, late <br />attached exploration logs. The tests were performed in accordance with ASTM or AASHTO procedures. <br />E.3. Groundwater Measurements <br />The drillers checked for groundwater as the penetration test borings were advanced, and again after <br />auger withdrawal. The boreholes were then backfilled as noted on the boring logs. <br />BRAUN <br />INTERTEC <br />
