ASPHALT PAVEMENT STRUCTURE AND ASPHALT REINFORCEMENT
To provide an asphalt pavement structure and asphalt reinforcement capable of increasing resistance to peeling of an asphalt layer from a crushed stone layer, preventing cracks from occurring on the lower surface of the asphalt layer, and suppressing deformation of the crushed stone layer due to wetting.SOLUTION: An asphalt pavement structure 2 comprises: a crushed stone layer 6 constructed above a roadbed 4; an asphalt layer 8 constructed above the crushed stone layer 6; and an asphalt reinforcement 10 embedded between the crushed stone layer 6 and the asphalt layer 8. The asphalt reinforcement 10 comprises: a sheet 20 having a thickness that absorbs and holds an asphalt emulsion E dispersed between the crushed stone layer 6 and the asphalt layer 8, and follows the unevenness of the upper surface of the crushed stone layer 6; and a geogrid 22 stacked on the sheet 20.SELECTED DRAWING: Figure 1
【課題】砕石層からのアスファルト層の剥離抵抗性を高めると共に、アスファルト層の下面にひび割れが発生するのを防止し、かつ、湿潤化による砕石層の変形を抑制することができるアスファルト舗装構造物およびアスファルト補強材を提供する。【解決手段】アスファルト舗装構造物２は、路床４の上方に構築された砕石層６と、砕石層６の上方に構築されたアスファルト層８と、砕石層６とアスファルト層８との間に埋設されたアスファルト補強材１０とを備える。アスファルト補強材１０は、砕石層６とアスファルト層８との間に散布されるアスファルト乳剤Ｅを吸収して保持し、砕石層６の上面の凹凸に追従する厚みを有するシート２０と、シート２０に重ねられたジオグリッド２２とを含む。【選択図】図１
