REGENERATION METHOD OF ASPHALT FOR ROAD PAVEMENT
To provide a regeneration method of asphalt for road pavement capable of increasing a loss tangent of deteriorated asphalt by a visco-elasticity measurement test and closing a crack of a deteriorated asphalt mixture under a temperature environment lower than a heating temperature of an on-road surface layer regeneration construction method.SOLUTION: A regeneration method includes a step (SA) of permeating a liquid composition containing an emulsion from the surface of a deteriorated asphalt mixture to the inside of the deteriorated asphalt by at least one treatment of spraying and coating, and satisfies the following conditions (1) and (2). Condition (1): The penetration of the deteriorated asphalt mixture after the permeation of the liquid composition is 150% or more in proportion (percentage) to the penetration of the deteriorated asphalt mixture before the permeation of the liquid composition. Condition (2): The content of the marten component of the deteriorated asphalt mixture after the permeation of the liquid composition is 103.0% or more by mass (percentage) relative to the content of the marten component of the deteriorated asphalt mixture before the permeation of the liquid composition.SELECTED DRAWING: Figure 2
【課題】路上表層再生工法の加熱温度未満の温度環境下で、粘弾性測定試験による劣化アスファルトの損失正接を上昇させ、劣化アスファルト混合物のひび割れも閉塞できる、道路舗装用アスファルトの再生方法の提供。【解決手段】散布及び塗布の少なくともいずれか１つの処理により、劣化アスファルト混合物の表面から劣化アスファルトの内部へエマルションを含む液体組成物を浸透させる工程（ＳＡ）を含み、下記条件（１）及び（２）を満たす再生方法。・条件（１）：液体組成物が浸透した後の劣化アスファルト混合物の針入度が、液体組成物が浸透する前の劣化アスファルト混合物の針入度に対して、比率（百分率）で１５０％以上。・条件（２）：液体組成物が浸透した後の劣化アスファルト混合物のマルテン成分の含有量が、液体組成物が浸透する前の劣化アスファルト混合物のマルテン成分の含有量に対して、質量比（百分率）で１０３．０％以上。【選択図】図２
