Description

A kind of bituminous concrete and preparation method thereof
Technical field
The present invention relates to asphalt concrete technique field, and in particular to a kind of bituminous concrete and preparation method thereof.
Background technology
As Chinese Urbanization and process of industrialization are accelerated, caused sewage quantity is all constantly increasing every year in city. General sewage treatment plant after sewage disposal, will can all leave lower substantial amounts of sludge (SS).I is treated as to these sludge Each city of state and a great problem of sewage disposal unit, due to containing substantial amounts of pollutant in sludge, so must be carried out to it Further processing.
The more commonly used method of processing sludge is to be burned at present, and lower substantial amounts of sludge can be all left after sludge incineration Grey (SSA).Fluid bed is employed if the cities such as the Shanghai in China, Shenzhen, Hangzhou, Ningbo, Changzhou, Shaoxing, Wenzhou, Chengdu Sludge incinerator handles sludge, achieves better effects, but all left a large amount of pending sludge ash.SSA is a kind of dangerous Solid waste, generally require and first pre-process, then carry out security landfill.Therefore SSA processing cost is very high, and many enterprises are difficult to hold By, then treat as general fixed-end forces so that SSA does not obtain rational final disposal, turns into important environment risk source, Do not comprehensively utilized reasonably, cause the waste of resource.To sludge carry out innoxious and recycling treatment, change give up into Treasured, meet the requirement of recycling economy and sustainable development, be extremely important.
The processing to SSA is usually directly to fill SSA or as the organic fertilizer in agricultural production or application at present In ceramics.Research shows：SSA composition mainly includes SiO2、CaO、Al2O3And Fe2O3, this main group with ordinary cement It is identical into composition, hence in so that sludge ash is possibly realized as a kind of construction material.And up to the present, using SSA as pitch Aglite in compound, it is not disclosed also so far applied to Patents among highway engineering and preparation method thereof.
The content of the invention
The shortcomings that for above-mentioned prior art or deficiency, the technical problem to be solved in the present invention is to provide a kind of source is wide It is general, cost is cheap, can turn waste into wealth and simple bituminous concrete of manufacture craft and preparation method thereof.
In order to solve the above technical problems, the present invention has following form：
A kind of bituminous concrete, including pitch, burning sludge are grey and gather materials, wherein, the percentage by weight of the pitch is 3.0%~6.3%, the percentage by weight of burning sludge ash is 1.0%~6.0%, and the percentage by weight that gathers materials is 90.9%~94.6%, wherein it is described gather materials to be gathered materials by each grade formed according to certain grading ratio.
The pitch is matrix pitch or modified pitch.
The burning sludge ash is powdery, and its particle diameter is between 10-200um.
It is described gather materials for basalt aggregate, diabase gathers materials, shale aggregate, granite gather materials and one in limestone aggregates Kind is a variety of.
It is described gather materials in each grade gather materials according to Marshall grading or Superpave (high performance asphalt) level arranging Put, it is preferable that the AC (bituminous concrete mixture) or SMA (pitch agates in Marshall grading can be usedFat crushed stones compound) Design method is set.
The method for preparing the bituminous concrete, comprises the following steps：The pitch is weighed by certain weight ratio, burns dirt Plaster and gather materials；By the pitch, burning sludge ash and the progress mix that gathers materials；After mix, it is made available for scene stand The bituminous concrete of paving.
Compared with prior art, the beneficial effects of the invention are as follows：Raw material sources of the present invention are extensive, cost is cheap, are not required to Want large scale equipment processing and manufacture craft is simple；The present invention is using sludge ash as bituminous concrete raw material, and by sludge circulation Utilize, reduce pollution of the sludge to environment, can turn waste into wealth, energy-conserving and environment-protective.
