When the surface of pavement covered with snow is frozen, it is dangerous for vehicles and walkers. There are many ways to restrain the surface freezing of pavement and break the freezing layer of it. The restraint ways contain melting methods by heat, peeling ways by clearing snow work and breaking freezing layer methods (it is call as breaking methods) by traffic loads and so on. The breaking methods contain of using elastic material constructed on the pavement surface. When vehicles pass on it, the freezing layer is broken by shear stress and bending stress produced by deflections of elastic materials. The breaking method needs the lowest maintenance cost of all restraint systems of freezing layers One of the disadvantages of breaking methods is that the thicker is the freezing layer, the more difficult is it to break the layer by traffic loads. Now, it is hoped to examine the sphere of the methods. To investigate this sphere, this study contains as follows: (1) Deflections of elastic material in-situ in the peeling methods were measured by a portable FWD (Falling Weight Deflectometer); (2) Deflections for these methods were estimated by analytic methods; and (3) The sphere of the peeling methods was estimated by the elastic analysis. 3 types of breaking methods on asphalt pavements were adopted in this study. These were as follows: (1) A cylindrical rubber with a diameter of 75 mm had a thickness of 25 mm pasted on the pavement; (2) A wasted tyres rubber pasted on an inter-rocking block that is called IL block; and (3) A grooving method with urethane material situated on the pavement. From the examination of this study, it is concluded that breaking methods have effect on freezing layer thickness of under 50 mm that depend on wheel loads.
