Construction Quality Assurance A) Plan Extension of Closure Cap <br /> Corral Hollow Sanitary Landfill August 21,2008 <br /> 3.2.2 Test Frequencies <br /> Tables 3-1 and 3-2 establish the test frequencies for earthwork CQA. The test <br /> frequencies listed establish a minimum number of required tests. Extra testing must <br /> be conducted whenever work or materials are suspect, marginal, or of poor quality. <br /> Extra testing may also be performed to provide additional data for engineering <br /> evaluation. Any re-tests performed as a result of a failing test do not contribute to the <br /> total number of tests performed in satisfying the minimum test frequency. <br /> TABLE 3-1 <br /> ENGINEERED FILL CONSTRUCTION TESTING FREQUENCIES <br /> ASTM TEST METHOD FREQUENCY <br /> Visual-Method Soil Classification (D2488) Continual during excavation of borrow <br /> materials <br /> Moisture-Density Relations Curve (D1557) 1 per 10,000 cubic yards or at least one per <br /> material type <br /> Particle Size (D422) 1 per 10,000 cubic yards or at least one per <br /> material type <br /> Density, Nuclear Method (D2922) 1 per 1,000 cubic yards <br /> Moisture, Nuclear Method (D3017) 1 per 1,000 cubic yards <br /> Moisture Content (D2216) 1 per 10 nuclear moisture tests <br /> TABLE 3-2 <br /> VEGETATIVE SOIL COVER LAYER CONSTRUCTION TESTING FREQUENCIES <br /> ASTM TEST METHOD FREQUENCY <br /> Sieve Analysis (D422) 1 per 5,000 cubic yards <br /> 3.2.3 Soil Sample Numbering <br /> The CQA Monitor shall maintain soil sample numbers in a master log maintained at <br /> the site.
