What 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

The 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..

5
Pull 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.

6
Check 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.

7
Check 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.

8
Flatness 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.
