3What is the asphalt finisher used for finishing
with pavement?
- The asphalt finisher uses a heavy machine that
performs the pallet construction of the base
layer and the surface layer which is the final
process of asphalt pavement work. - As a structure, it is divided into a tractor
section equipped with a self-propelled function,
a hopper filled with heated asphalt mixture, and
a screed which presses out the asphalt mixture on
the paved surface and disposes of it. - The asphalt mixture that has been carried in the
dump truck is first stored in the hopper, and if
it can fill the amount necessary for
construction, it sends it to the screen with a
roller and spreads the putty on the road so that
it is filled with a spatula
4The quality control method of asphalt construction
- Strict quality control standards are established
for asphalt pavement which is supposed to be used
for many years. - Since the asphalt mixture is a paste, there are
various factors that determine the quality, such
as the temperature during mixing, the degree of
mixing, and whether the pressure reduction is
secure. - At the same time, there is also difficult to
judge simply by looking at the pavement from the
outward appearance. Therefore, it is possible to
do a test to check the quality during
construction of the asphalt pavement and after
construction, and to pass it through to finalize
it..
5Pull flooring test to check the failure of the
roadbed
- The pull flooring test is a test conducted before
the asphalt mixture is laid, at the stage when
the roadbed is exposed. - Pass out a loaded dump truck etc. on the crushed
stone of the compacted roadbed and check whether
there is any problem on the roadbed surface after
passing through the track. - The examination is done by visual observation,
and if you find a defective part on the roadbed
surface, you need to take some remedial measures
such as temporarily removing the material used in
that part and replacing it with good quality
material.
6Check the amount of asphalt without core
- Core removal is a test that is performed after
the completion of spreading asphalt mixture and
after drying is completed. Determinate points
randomly on the finished paved surface, drill
holes in the place and pull out a part of the
asphalt mixture spread over the surface layer and
base layer. - You can see from the sampled model whether the
aggregate contained in the mixture meets the
prescribed particle size, the asphalt at the
bridge is how much the specified amount is used
or how compacted by compaction. It is an
important test to check the quality of the
surface layer and the base layer which are
exposed to the weathering and load most in the
pavement.
7Check compaction degree of roadbed in field
density test
- The density test is a quality test conducted
after the roadbed finishes. Drill a hole in the
compacted roadbed to recover a part of the
roadbed material and fill the empty hole with
sand. This is a construction method called sand
substitution method, and we first reveal the
volume according to how much sand entered. - Consider the recovered roadbed material and
divide it by the volume that was clarified ahead
of time to derive the density of the roadbed
material by calculation. If the roadbed is
tightly compacted, it should satisfy the
prescribed density, so it is the dimension that
you can check the compaction condition of the
road by measuring the density. - The degree of compaction is directly linked to
the load carrying capacity of the roadbed, and if
the compaction is insufficient, there is a danger
that the paved surface can withstand the weight
of the car traveling above it.
8Flatness test checks road flatness
- The flatness test is a test carried out after the
finish of the surface asphalt mixture is
completed. Use a flatness measuring instrument
such as a wheelbarrow called 3 ? profile meter
and check whether the pavement surface is
flattened neatly. - If the pavement surface is not flat, rainwater
may accumulate in unintended places and become a
puddle, or it may become a problem to the person
passing over.
