《Highway road surface construction technology detailed rules and regulations》Middle regulation：The compacting of basic unit should first use steel roller first pressing, then
The rubber-tyred roller for being more than 35t heavy-duty shocks forcing press, 18-21t three-roll road rollers or more than 25t with exciting force is pressed again.《It is public
Road Asphalt Pavement Construction Technique specification》Middle regulation：To the compound of the greater particle size based on coarse aggregate, especially big particle diameter drip
Blue or green stabilized macadam base, it is preferably preferential to be pressed again using vibrated roller, high-frequency large amplitude is selected when thickness is larger, it is larger to produce
Exciting force, when thickness is relatively thin use high-frequency short arc, to prevent aggregate crusher.
During practice of construction, the frequency of use of vibrated roller is very high, often needs the resistance to crushing energy to coarse aggregate
Index is tested；But current Mechanics Performance Testing index can't preferably react the resistance to compression of the lower coarse aggregate of oscillatory load effect
Fragility energy.One be crush values index mainly characterize be coarse aggregate under action of static load crushing loss, with non-vibration forcing press
Action principle it is similar, it is impossible to preferably reaction coarse aggregate oscillatory load effect under crushing loss；Two be the actual stone roller of road roller
During pressure load be it is movable, crush values test device can not preferable analog vibration road roller the mode of action, crushing
Value index fails preferably to react the resistance to crushing energy that gathers materials；Three pressure heads when being crushing value test are easily contacted with die trial side wall, cause to apply
Loading, which is carried, has error, and there is certain " boundary effect ".
The content of the invention

Head, the upper end of transmission rod is hinged with sliding force-transmitting block, and lower end is connected with pressure head, in the lower surface of pressure head and coarse aggregate packing groove
Test material contact.
Above-mentioned crushing coarse aggregates value test device is that the pressure head is length of side 150mm, thickness 25mm cube metal
Plate.
Above-mentioned crushing coarse aggregates value test device is that described coarse aggregate packing groove is made up of cylinder and floor combination,
Cylinder is long 400mm, width 250mm, wall thickness 20mm cuboid frame, and bottom plate is long 460mm, width 310mm, thickness 30mm metal
Plate.
Compared with the prior art, the beneficial effects of the utility model are：
The utility model is fixedly connected with two root posts on the vibration area of vibration machine, is set between two root posts
Crossbeam, wears the slip force-transmitting block that connects and can slide on crossbeam, and coarse aggregate packing groove is set in the lower section for sliding force-transmitting block,
Sliding, transmission rod and pressure head are set between force-transmitting block and coarse aggregate packing groove；, will be to be detected when doing the test of crushing coarse aggregates value
Coarse aggregate sample be placed in coarse aggregate packing groove, adjustment pressure head make it be slightly compressed to be placed in coarse aggregate packing groove on coarse aggregate
High order end or low order end, the loading parameter of vibration machine is set, and Vibration on Start-up generator, vibration machine vibrated
Conduction is to column, crossbeam, slip force-transmitting block, transmission rod until pressure head, passes through vibration machine and produce different frequency, various amplitude
Oscillatory load can carry out crushing coarse aggregates value test.It is capable of the mode of action of preferable analog vibration road roller using the present apparatus,
Preferably crushing loss of the reaction coarse aggregate under oscillatory load effect, is that the resistance to crushing gathered materials under vibrated roller is acted on can be carried
For a kind of reliable Testing index；Meanwhile, the present apparatus also have the advantages that it is simple in construction, prevent interference.
