Engineering *remember to utilize your lecture notes. Questions The following is a list of questions (to be considered) as a guideline for information/data that should be incorporated into your lab report. 1. What equipment and/or method were used to perform tests and obtain results? 2. Details of specimen preparation, such as wet or dry – refer to ASTM D6913 test procedures and appendices – as applicable. 3. Include a graph of the percent passing versus the log of particle size in mm. 4. What were the values you determined, as in; D60, D10, D30, Cc and Cu? 5. What was the soil type tested according to the Unified Soil Classification System – what is the soil group symbol, and what does the symbol mean? 6. What were the values determined in pt. 6 and 7 of the Results/Reporting section? What do they represent? 7. Was the soil well graded, poorly graded, or gap graded by analyzing the graph? 8. Were there any errors/complications in the testing completed? Selected References 1. Das, B.A., 2010, Principles of Geotechnical Engineering, Cengage Learning 2.
