Slipping
174
When a path traveled along the road
surface is more than the circumferential
movement of the tires due to rotation, what
is the resulting motion of the tires?
Skidding
175
Immediately following or during edging,
pre-molded inserts are placed in concrete
slabs to control cracking in the concrete as
a result of shrinkage.
Jointing
176
The bringing of a concrete surface to
true grade with enough mortar to produce the
desired finish.
Leveling
177
The surface of newly placed concrete is
struck off by moving a straightedge back and
forth with a saw-like motion across the top
of the forms
Screeding
178
Generally, the dry materials used in
making quality concrete are heavier than
water. Thus, shortly after placement, they
have a tendency to settle to the bottom and
displace the mixing water to the surface,
which is called _____.
Bleeding
179
Cracks forming large interconnected
polygons, usually with sharp corners or
angle. These cracks are generally caused by
hardening and shrinkage of the asphalt and
or reflection cracking from underlying
layers such as cement-treated base.
Block cracking
180
A series of interconnected or interlaced
cracks caused by fatigue failure of the
asphalt concrete surface under repeated
traffic loading.
Alligator cracks
181
Localized upward buckling and shattering
of the slabs at transverse joint or cracks.
They can occur when transverse joints are
filled with incompressible solid materials.
Blowups
182
Elevation differences between adjacent
slabs at transverse joints. It is usually
the result of pumping and is a major source
of Portland Concrete pavement structure.
Faulting
183
The extruding of bitumen onto the
pavement surface, causing a reduction in
skid resistance. It is generally caused by
excessive amounts of asphalt in the mix or
low air voids content. It occurs when asphalt
fills the voids in the mix during hot weather
and then exudes out onto the surface of the
pavement.
Bleeding or Flushing
184
Progressive disintegration of the
surface between the wheel paths caused by
dripping of gasoline or oil from vehicles.
Drip track raveling

187
