Psad Flashcards
It is the process of bringing earthwork to the desired shape and elevation
Grading
It is the process of giving a chiral soils and off abrasive resistance and shear strength to accommodate traffic or design loads
Soil stabilization
It is the process of bringing each roadway layer to its final grade
Trimmings
It is the process of increasing the density of a soil by mechanically forcing the soil particles closer together there by expelling the air from the void spaces in the soil
Compaction
It is the process of increasing the density of a cohesive soil from the expulsion of water from the soil void spaces
Consolidation
Complete or partial dismantling of a building or structure by pre-planned & control methods or procedures
Demolition
The action of flattening poured concrete into a smooth flat layer prior to finishing the surface
Screeding
It is the bringing of a concrete surface to true grade with enough mortar to produce the desired finish
Leveling
It is the measure of the materials ability to resist indentation or penetration
Hardness
It is the ability of a material to deform in the plastic range without breakage or or the ability to undergo considerable plastic deformation under tensile load before actual rapture
Ductility
It is the ability of a material to absorb energy before fracture takes place
Toughness
It is the ability of a material to recover its shape and size after deformation
Resilience
When material has to support a load for a long period of time what causes it to continue to deform until a sudden fracture occurs?
Creep
When a material is subjected to repeated cycles of stress or strain what causes its structure to breakdown ultimately leading to fracture
Fatigue
It is the point where the object suffers note or by the effect of the gravitational force acted upon it
Center of gravity
It is point through which the resultant of the resistance to the applied lateral force acts
Center of rigidity
