Definition of Terms Transportation Engineering Flashcards
(15 cards)
a series of
interconnected of interfaced cracks caused
by fatigue failure of the asphalt concrete
surface under repeated traffic loading
Alligator cracking
the height between the trough
and the crest of a wave
Amplitude
a layer consisting of
properly designed mix of coarse aggregate
fine aggregate, a filler and a bituminous
binder
Asphaltic Concrete
the average of the spot
speeds of all vehicles passing a given point
in the highway
Average speed
highway appurtenances designed to
prevent vehicular penetration from the
travel way to areas behind the barrier such
as to minimize damage to impacting vehicles
and their occupants and to reduce the risk
of injuries to pedestrians and workers
Barriers
the component of the road structure
which receives the traffic load and transfer
it to the subgrade
Base
this normally consists of
aggregates such as gravel and crushed rock
Base courses
the max number of passenger
cars that can pads a given point on a lane
or roadway during one hour under the most
nearly ideal roadway and traffic conditions
which can possible be attained
Basic capacity
process of proportioning cement,
water, aggregates and additives prior to
mixing concrete
Batching
the physical configuration of
the seabed, the measurements of depths of
water in the ocean, etc. and also
information derived from such measurement
Bathymetry
an instrument use to
measure intensity of wind
Beuforts Scale
the mooring fitting for mooring ships
during a storm installed close to the water
line of the berth
Bitt
a 20 mm thick premix
bitumen layer over which is laid a seal coat
Bitumen carpet
the exuding of
bitumen onto the pavement surface causing a
reduction in skid resistance
Bleeding or flushing
cracks forming large
interconnected polygons, usually with sharp
corners or angles. These cracks are
Block cracking
