FDOT Earthwork Study Guide With Solutions - Complete Solutions Updated Basics covered in Level 1 - answer - Nuclear Testing Speedy Moisture Report Forms Earthwork has to do with the roadway in what way? - answer - Earthwork is the excavation and placement of soils and materials supporting the proposed roadway. In Earthwork what is a lift? - answer - 6" of compacted depth at full width In Earthwork what is a Lot? - answer - A lot is 1 lift at 500 ft or within compacted area. Isolated compaction operations are separate lots. Sampling at the roadway is done for - answer - Done for base, sub grade, and embankment. Sampling is determined how - answer - generated with random numbers usually by a Verification Inspector What is important about sampling at the roadway - answer - Minimum of three representative sample combined. What is LIMS? - answer - Laboratory Info Management System The proctor theory is when compaction is achieved how - answer - by inputting energy to expel air and water in the soil voids Compaction causes - answer - An increase in unit weight, decrease in compressibility and permeability. The proctor is determined where and creates what - answer - In a laboratory and establishes a density standard to be used on the roadway Lab proctors are created how - answer - Material is gathered from the road and prepared with different amounts of water then placed in molds and hammered What is a modified proctor used in - answer - It is used in base, sub grade, MSE wall back fill materials Modified proctors are created how - answer - With a 10lb hammer(rammer) on a 18" drop with 56 blows per layers with 5 layers in total. What is a standard proctor used in - answer - It is used in embankment and structure back fill materials Standard proctors are created how - answer - With a 5.5lb hammer(rammer) on a 12" drop with 25 blows per layer with 3 layers in total Comparison between VT and QC density test tolerance - answer - 2 lbs/pcf What is the STRG - answer - Sampling, Testing, and Reporting Guide (state wide) A job guide schedule is - answer - project specific The material identification number for embankment in the laboratory is - answer - 004L The material identification number for embankment in the field is - answer - 004F The material identification number for base is - answer - 030 PP is short for - answer - project personel Sampling in the field it is important to - answer - sample each type of material and have enough for a representative sample When to secure samples - answer - After material is placed but before compaction effort is applied Sample transmittal card the source uses what code for the jobsite - answer - 08 For material description the minimum is always - answer - Color and texture On sample bags be sure to put - answer - Project # Sample # Location What is the document that itemizes the minimum requirements for sampling and testing? - answer - Sampling, testing, reporting guide Unit weight is - answer - the weight of a material occupying a volume Wet density - answer - is the weight of soil and water in a volume Dry density - answer - weight of soil solids in a volume Moisture content - answer - amount of water in the soil in the volume How does moisture react with soil - answer - acts as a lubricant permitting maximum densification Compaction expels air and water causing - answer - Increase in unit weight and Decrease in compressibility and permeability (ability of water to flow through) MSE wall stands for - answer - Mechanically stabilized earth wall FM 1 T-80 refers to which proctor - answer - Modified AASHTO T 99 refers to which proctor - answer - Standard Density is the measuring of - answer - the dry density of soil compared to max dry density determined by proctor % compaction When is the density be more than 100% of the maximum dry density on the proctor test? - answer - If compactive effort is more applied in field than lab Direct transmission is - answer -
