Description
Technical field
The invention belongs to Communication and Transportation Engineering field, more particularly to a kind of combined multifunctional bicycle rut panel assembly.
Background technology
At present, as the innovation ad hoc planning of China " 13 " national science and technology is formally implemented, scientific progress and its level
Improve the motive power for no doubt becoming that innovation-oriented country's construction leads and supports upgrading development.This device is in Communication and Transportation Engineering field
Wheel tracking test research and its scientific research progress play the role of promotion, the therefore invention of this device has great significance.
According to China《Highway engineering Colophonium and Asphalt Mixture Experiment code》Specify in JTG E20-2011, Colophonium mixes
Truck rut board size is long 300mm, wide 300mm, 50～100mm of thickness, also dependent on needing to be adjusted its thickness.But it is original
Mould adjusts thickness in any case and can only all simulate a kind of wheel tracking test of asphalt in pavement structure, this wheel tracking test
The high temperature stability performance of this asphalt of explanation that as a result can only be single, and various asphalt compound can not be reflected on road
The impact of the lower road pavement rut of interaction between the layers of face, while layer that can not be between simulated roadway layers
Between shear action, accordingly, it can be said that this test component form does not meet road surface each Rotating fields design and feelings are applied on actual road surface
Condition.Such as, Research on Asphalt Mixture match ratio is the high-temperature stability of AC-13（Rut）During property, it is impossible to which single only studies
Itself, it is just more meaningful to put it in the pavement structure of practical application research, because in different surface layer structures
Under different pavement structure forms, the high-temperature stability of AC-13 asphalt（Rut）Property is different；Meanwhile, respectively
The difference of surface layer asphalt pavement material, the wheel tracking test result test knot a kind of with only research monolayer in the case of variable thickness sample
Fruit is also different；For another example, in the presence of traffic load, road surface difference surface layer interlayer junction can exist interlayer cut should
Power, this is larger to actual road surface effect, and original rut mould can not do interlayer shear-strength test, it is impossible to meet actual demand；
As can be seen here, original rut test piece mould can neither comprehensive each layer Pavement Structure Design, interlayer shear-strength test can not be done, not be inconsistent
Close the applicable cases on actual road surface.
