Studying carefully, its core is the propagation law that clear and definite temperature load and traffic load act on lower Reflective Crack in Asphalt Overlays jointly, and it is main
Wanting solution is to bear opposing reflection crack when stretch-draw effect and shear action by Experimental Method in Laboratory research bitumen layer
Ability.
For reflection crack problem, the most still without effective solution and reliable prediction model, more lack unification
Test method.Instrument and test method that different researcheres use are different, and achievement in research is difficult to be approved widely.Portion
The opening mode dividing existing instrument and equipment to be only capable of individually studying bitumen layer destroys or shearing-type destroys, and it is real not meet composite runway pavement
The External Force Acting that border is suffered during using.
