MSTE Flashcards
It is to determine whether a
concrete has the specified compressive strength
Compression test
the root mean square of the
deviations about the arithmetic mean of a set of
values.
Standard deviation
it is sum of scores divided by the number of
cases.Popularly known as the average.
Mean
It is the middle number of a set of numbers arranged in order
Median
Value which occurs most frequent in given distribution
Mode
Source of error in taping when tape may differ in actual length from its nominal graduated length because of a deflect in manufacture or repair
Instrumental error
A taping error due to affects of temperature, pull and weight of the tape itself
Natural error
Taping error due to a setting of pins, reading the tape or manipulating the equipment
Personal ERROR
Defined as a number of vehicle passing a point on highway or given lane or direction of a highway in specific time
Volume
Generally expressed in units of veh/hr but represents the flow thst exists for period of time less than an hour
Rate of flow
Average speed of all vehicles passing a point over a specified time period
Time mean speed
Average speed of all vehicles occupying a given dection of roadway over a specific time period
Space mean speed
Number of vehicles occupying a road lane per unit length of a given instant in time
Density
Maximum sustained 15 min flow rate, expressed in passenger cars per hr per lane
Capacity
Used to define two or more points that lie on the same line
Collinear
Lines that are spaced equally apart across all of their length and do not intersect
Parallel
Objects with the same shape and size and size as the mirror image or object
Congruent
Lines in three dimensional space that lie on the same plan
Coplanar
Objects forming right angles
Perpendicular
A plane figure bounded by three straight sides
Triangles
Useful in determining the shearing strength assistants along recognizable weal planes within the soil material
direct shear stress
Determines the asphalt content of liquid asphalt
Distillation test
Measures the ability of the ashfall to stretch without breaking
Ductility test
To determine the amount of pascal present in mix
Extraction test
Measures the distance that standard needle will penetrate a sample at a given temperature in a specified time
Penetration test
Localize upward buckling and shattering of the slab a transverse joints or cracks
Blow up
The breakdown or disintegration of slab edge at joints or cracks
Joint or crack spalling
The process of wearing away a surface due to friction
Surface abrasion
The difference in elevation between the joints do to settlement of pavements erosion of material under the pavement and change in temperature
Faulting
