Description
Technical field
The utility model belongs to bituminous pavement property valuator device technical field, specifically, relates to a kind of beam shape test specimen bogey for the torture test of asphalt rut.
Background technology
Rut fatigue refers to that material destroys under lower than ultimate load effect of stress, is the expansion of micro-crack under Repeated Loading.During pavement usage, under ambient temperature effect, stand the repeated action of wheel load.Its stress or strain, for a long time in variable condition, cause pavement structural strength to decline gradually.After load repeat function exceedes certain number of times, the stress producing in road surface will exceed the structure reactance after pavement structural strength declines, and makes road surface produce fatigue crack.The early stage phenomenon of fatigue crack is that road surface continual crack, finally causes road surface to occur check crack, be full of cracks in longitudinal appearance, even cheats groove.The fatigue behaviour of bituminous concrete and the serviceable life of bituminous pavement are closely related, in the life-span that it has reflected road surface, have reflected tens million of inferior repeat functions under little tonnage load action, the effect that dripping water wears through rock.Therefore, fatigue break, as the main damage form of bituminous pavement, also more and more attracts much attention, and Research on Asphalt Mixture rut fatigue behaviour just has great significance.
At present, the asphalt normal repeated bending fatigue that adopts fatigue lifetime is tested or indirect tensile fatigue test evaluation, but the control mode of torture test has a significant impact tool fatigue lifetime of compound.Under identical strain level, long by the fatigue lifetime of Stress Control by the fatigue life ratio of strain control.And press in the torture test of different mode control, the trend that the various parameters that characterize asphalt characteristic change variation fatigue lifetime causing is contrary sometimes.For this reason, based on existing rut equipment, while having people to change it, and propose one neither Stress Control pattern neither strain control model, and more can reflect the lab simulation accelerated test of the actual state on road surface.But traditional rut die trial, is mainly used in the board-like bituminous concrete test specimen of fixing 300mm × 300mm × 50mm, and forms even support in its underpart, this traditional die trial cannot be used for rut torture test.
