Abstract: 本研究は寒冷期と通常期に3種類の初転圧用ローラーを用いた場合におけるアスファルト舗装の温度と空げき率について検討を行ったものである。また,施工面を加熱した場合と常温切削した場合についても同様の検討を加えた。実験の結果,空げき率は施工面の温度に著しく依存し,寒冷期施工のアスファルト混合物は通常期のそれと比較して空げき率が大きいこと,また転圧機械の種類,施工面の凹凸形状,施工厚さや配合によっても空げき率とその深さ方向の分布は異なることが明らかにされた。
This paper describes temperatures and void ratios of asphaltic layers constructed using three roller types in cold and ordinary seasons, and the effects of heating and cold cutting of the surfaces in lower layers. The following conclusions were obtained: The void ratios of asphaltic layers constructed in cold season were larger than those of layers constructed in ordinary season due to the effect of temperatures in the lower layers. The void ratios and their vertical distributions of asphaltic mixtures were influenced by roller types, roughness of the surfaces in the lower layers, gradation and thickness of the mixtures.
