To provide a thawing method and a device capable of simply and certainly thawing a frozen subgrade/subbase course when road paving work is performed at a cold zone during winter season and solving trouble caused by ice remaining in the subgrade/subbase course.
As making a power shovel truck 3 travel with a weight bag 5 hung from a power shovel 3A of the power shovel truck 3, a heat of reaction producing material such as raw lime contained in the weight bag 5 is sprinkled on the road, which is followed by pulverizing the frozen subgrade/subbase course 1 and mixing the pulverulent by a pulverizer 4A as making a road stabilizer 4 travel. This troubule caused by ice remaining tin the roaded 1 is solved by sufficiently thawing ice and allowing to carry out rolling satisfactory thereafter. The frozen subbrade-subgase course may be thawed by heat of quantity of superheated steam by mixing superheated steam into the frozen subgrade/ subbase course instead of using the heat of reaction producing material.
