Description
Technical field
A kind of asphalt mortar, bituminous mortar specimen molding mould of hexagonal honeycomb structure is the utility model is related to, belongs to road engineering skill
Art field.
Background technology
With the development of asphalt rubber cement theory and the demand of multiscale analysis, more and more pavement materials are ground
Study carefully and goal in research is switched into bituminous cements, asphalt mastic, asphalt mortar, bituminous mortar, asphalt multiscale analysis system.Wherein pin
High speed shear rheometer DSR (Dynamic are usually passed through to the material property testing of bituminous cements, asphalt mastic, asphalt mortar, bituminous mortar
Shear Rheometer) carry out.When carrying out DSR experiments, the shaping of bituminous cements and asphalt mastic is typically to use to pour circle
The mode of shape die trial.And fine aggregate is contained in asphalt mortar, bituminous mortar, i.e., gathering materials below nominal maximum aggregate size 2.36mm, using pouring
The mode of circular die trial is difficult to meet the needs of shaping test piece size, it is also difficult to meets to add the compaction moulding demand after gathering materials.
Conventional method usually according to bitumen mixture specimen test specimen size, using marshall compaction or gyratory compaction method into
Type test specimen and then the method using cutting, are cut into the prism that size is 10mm × 10mm × 50mm.But cutting obtains
Test specimen due to size it is smaller, the error resulted in cutting process is just particularly evident, meanwhile, material is easy to cause in cutting process
The disturbed destruction of the internal inherent structure of material, causes result of the test can not truly reflect the virtual condition of material.
The content of the invention
The utility model will solve technical problem：The shortcomings that overcoming above-mentioned technology.There is provided one kind can straight forming it is small
Size asphalt mortar, bituminous mortar test specimen, while marshall compaction or the molding die of gyratory compaction molding method can be utilized again.
In order to solve the above-mentioned technical problem, the utility model proposes technical solution be：A kind of hexagonal honeycomb structure
Asphalt mortar, bituminous mortar specimen molding mould, including：Die ontology, top plate, bottom plate and demoulding tooling；The die ontology is cylinder,
With the hexagonal hole that several are penetrated through from top to bottom in it；Have on the top plate and bottom plate a pair of with the hexagonal hole one
The hexagonal prisms answered；The hexagonal prisms is inserted into the hexagonal hole；The demoulding tooling includes pedestal and is arranged on pedestal
On some demoulding columns；The demoulding column is corresponded with the hexagonal hole, and is inserted into the hexagonal hole.
Such scheme, which further improves, to be：The demoulding column is in hexagon.
Such scheme, which further improves, to be：Have in the die ontology 61 in honeycomb arrangement from top to bottom
The hexagonal hole of perforation.
The asphalt mortar, bituminous mortar specimen molding mould of hexagonal honeycomb structure provided by the utility model can make full use of routine
Asphalt marshal piece or gyratory compaction molding equipment, cylindrical die and supporting top plate, bottom by hexagon
Plate, demoulding tooling, realize that one-pass molding operation obtains more asphalt mortar, bituminous mortar hexagonal prism body test specimens, for dynamic shear rheological
Research of the instrument DSR equipment to asphalt mortar, bituminous mortar mechanical characteristic.The utility model design shaping logic is careful, and molding die simplicity makes
With method is rationally easy, and need not be equipped with dedicated shaping loading equipemtn.Involved shaping in being designed by the utility model
The asphalt mortar, bituminous mortar test specimen that mould obtains, can avoid using material damage and scale error caused by cutting technique, realize material
The uniformity of characteristic and sample dimensions, uniformity, can effectively be lifted the reliability of follow-up dynamic characteristic test result with effectively
Property.The utility model for the improvement and research and development in scientific research activity to asphalt mixture material performance, in engineering practice to material
Expect the detection and evaluation of performance, be respectively provided with highly important effect.
