Paveio(u)r of the present invention further specify and advantage can be described below.
The content of aggregate has accounted for majority in the asphalt pavement material, and the resource of natural aggregate has been very poor in Japan, in addition, fells natural aggregate in a large number and can cause natural destruction.In asphalt pavement material of the present invention, because comprising rubbish, the aggregate that is adopted burns grey slag and steel slag, the natural aggregate resource of rubble etc. can be saved in large quantities.Because the burning of burning but from rubbish but ash has obtained utilization, the present invention also help rubbish effectively and harmless treatment.
The grey slag of rubbish burning is to do to obtain after the slag shaping processing by the residue (burning but ash) after burning but to rubbish, its hardness, and abrasivity and safety are all not second to natural aggregate.Then, according to the difference of the material of rubbish, a part of rubbish burns grey slag because relatively more fragile, thereby only has lower intensity, so be necessary that recrystallizing (fusion) by heating handles.In addition, be shaped to handle and the grey slag of burning that obtains, perhaps, accept the processing of cooling off gradually again through the grey slag of burning that obtains after the crystallization treatment of heating/again, till the grey slag of this burning is cooled to environment temperature through slag.Through after the cooling processing gradually, the final rubbish that obtains burns grey slag to have than higher intensity.
In addition, do the slag processing by rubbish being burnt but ash, burn the metal species that is contained in the but ash and can be melted and be separated, therefore this slag will not have the problem of corrosion after being used as paveio(u)r.The grey slag of burning that is obtained is handled in shaping through slag, perhaps through after the crystallization treatment of above-mentioned heating/again and the grey slag of burning that obtains is accepted the processing of cooling off gradually again, and accept again to pulverize and sieve after the processing, the rubbish that can obtain to have certain intensity and have the homogeneous size distribution burns grey slag.
Moreover owing to the aggregate that also is used as asphalt pavement material from the steel slag of iron-smelter, the intensity of asphalt pavement material can be further enhanced.
In addition, because have the category of glass of glossiness and the aggregate that the plastics class is used as asphalt pavement material, the ornamental and identity on the road surface after paving the way with this material has obtained further raising.
Adopt above-described asphalt pavement material to implement when paving the way operation, because the part of aggregate has been in the slag state, make comparisons with the asphalt pavement material (aggregate is discarded bituminous material) of the aggregate that adopts prior art, paving the way, can obtain shortening required cool time in the operation, so can shorten construction period.
Again, because in aggregate, sneaked into the particle of category of glass and plastics class, can form slight gap in the asphalt pavement material after paving the way, then can be so that external liquid such as rainwater be discharged from by above-mentioned slit, thus formed a kind of asphalt pavement material of water permeability.
