高胶超薄罩面乳化沥青黏层强度形成规律研究
摘要
Abstract
In order to analyze the performance influencing factors and strength formation rules of rubber-SBS composite modified emulsified asphalt as a high rubber content ultra-thin overlay adhesive layer,different emulsified asphalt spraying amounts were used.SMA-5,II-type,and PA-5 gradations representing dense gradation,semi open gradation,and open gradation respectively were used to form high rubber content ultra-thin overlay composite specimens.The bond strength at different curing ages were tested.The effects of water evaporation on the phase angle,complex shear modulus,and rutting factor of emulsified asphalt during room temperature curing were analyzed.The fluorescence micro-structure of emulsified asphalt at different curing ages were tested to analyze the strength formation mechanism of rubber-SBS composite modified emulsified asphalt.The research results show that the rubber-SBS composite modified emulsified asphalt can achieve a bonding strength of 0.56 MPa at 20℃for high rubber content ultra-thin overlay.The optimal spraying amount of emulsified asphalt is 1.15 kg/m2.The mixture type of the overlay layer has a significant impact on the bonding strength.The bonding strength gradually increases with the curing time,which is consistent with the rheological index increasing of rubber-SBS composite modified emulsified asphalt as the curing time.The micro particles and polymers of rubber-SBS composite modified emulsified asphalt continuously gathered with water evaporation to forming strength.关键词
