Mste Flashcards
What does Construction Management refer to?
It may refer to the contractual arrangement under which a firm supplies construction management services to an owner.
What activities are included in Quality Management?
Quality management includes specification development, process control, product acceptance, laboratory and technician certification, training, and communication.
What is Quality Control (QC) primarily concerned with?
QC is primarily concerned with the process control function.
What is Earthmoving?
Earthmoving is the process of moving soil or rock from one location to another and processing it to meet construction requirements.
What does Trafficability refer to?
Trafficability is the ability of a soil to support the weight of vehicles under repeated traffic.
What is Loadability?
Loadability is a measure of the difficulty in excavating and loading a soil.
What is Plate Line Capacity?
Plate line capacity is the bucket volume contained within the bucket when following the outline of the bucket sides.
What is Struck Capacity?
Struck capacity is the bucket capacity when the load is struck off flush with the bucket sides.
What does Water Line Capacity assume?
Water line capacity assumes a level of material flush with the lowest edge of the bucket.
What is Heaped Volume?
Heaped volume is the maximum volume that can be placed in the bucket without spillage based on a specified angle of repose for the material.
What is a Dragline?
The dragline is a very versatile machine that has the longest reach for digging and dumping of any member of the crane shovel family.
What are Cranes primarily used for?
Cranes are primarily used for lifting, lowering, and transporting loads.
What does Grade Resistance represent?
Grade resistance represents that component of vehicle weight which acts parallel to an inclined surface.
What causes Rolling Resistance?
Rolling resistance is primarily due to tire flexing and penetration of the travel surface.
What is Fixed Time?
Fixed time represents those components of cycle time other than travel time.
What is Variable Time?
Variable time represents the travel time required for a unit to haul material to the unloading site and return.
What is Ground Modification?
The process of giving natural soils enough abrasive resistance and shear strength to accommodate traffic or design loads.
What is Compaction?
Compaction is the process of increasing the density of a soil by mechanically forcing the soil particles closer together.
What is Dynamic Compaction?
Dynamic compaction, or deep compaction, involves dropping a heavy weight from a crane onto the ground surface to achieve soil densification.
What is Vibratory Compaction?
Vibratory compaction is the process of densifying cohesionless soils by inserting a vibratory probe into the soil.
What is Surcharging?
Surcharging is placing additional weight on the soil surface to densify cohesive soils.
What does Soil Stabilization refer to?
Soil Stabilization refers to the improvement of the engineering properties of a soil by use of physical or chemical admixtures.
What is Grading?
Grading is the process of bringing earthwork to the desired shape and elevation.
What is Finish Grading?
Finish grading involves smoothing slopes, shaping ditches, and bringing the earthwork to the required elevation.
What is Balancing in highway construction?
Balancing is the process of cutting down high spots and filling in low spots of each roadway layer.
What is Trimming?
Trimming is the process of bringing each roadway layer to its final grade.
What are the phases of Rock Moving?
The process of rock moving may be considered in four phases: loosening, loading, hauling, and compacting.
