Description
Technical field
The utility model is related to pavement test equipment, and in particular to a kind of Multifunctional asphalt mixture performance tester.
Background technology
The circumference for testing wheel in traditional performance of asphalt mixture tester does not have protrusion, is mixed with experiment pitch
It is tangent to expect that road surface is integrally bonded, it is different from the tire construction in reality, cause test result not accurate enough, and usually test wheel
Glide direction is identical as the direction of motion of movable stand, without angle, is not easy to simulate the movement locus of tire on true road surface, also will
Cause test result not accurate enough；Moreover, can only testing experiment asphaltic road-mix surface course intensity, cannot simultaneously to bituminous paving
Carry out compacting operation.
Traditional performance of asphalt mixture tester experiment wheel is back and forth transported being put into clump weight on clump weight platform
When dynamic field compaction test asphaltic road-mix surface course, it is easy to cause clump weight shaking so that the actual weight of test is deviated, and is influenced
Test result；Also, it is not easily achieved accurate calculating test number (TN) during traditional experiment, test result is made not have enough
Objectivity.
