Quick-drying type SBR-modified emulsified asphalt sealing layer mixture and preparation method thereof

Abstract

The invention discloses a quick-drying type SBR-modified emulsified asphalt sealing layer mixture and a preparation method thereof. The mixture comprises the following components in parts by mass: 100parts of mineral aggregate, 11-13 parts of SBR-modified emulsified asphalt, 3-5 parts of cement, 3-5 parts of carbon fiber powder and 12-14 parts of tap water. The mixture has the advantages of beinghigh in strength, good in crack control effect and capable of being rapidly formed under a humid climate condition. The problems existing in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of highway engineering, and relates to a quick-drying SBR modified emulsified asphalt sealing layer mixture and a preparation method thereof. Background technique [0002] In preventive maintenance, modified emulsified asphalt sealant mixture is widely used, but in rainy areas with humid climate, emulsified asphalt road surface sealant mixture takes a long time to form, delaying traffic opening time, and long-term closed traffic intensifies The congestion of the city has been restricted, thus restricting the promotion and application of emulsified asphalt sealant mixture; based on the research at home and abroad, cement is conducive to accelerating the formation of emulsified asphalt sealant mixture, but due to the excessive cement content, the mixture will crack. The mixing quality of cement is generally controlled within 3%, and the efficiency of accelerating the mixture forming is limited, and there is no...

Problems solved by technology

[0002] In preventive maintenance, modified emulsified asphalt sealant mixture is widely used, but in rainy areas with humid climate, emulsified asphalt road surface sealant mixture takes a long time to form, delaying traffic opening time, and long-term closed traffic intensifies The congestion of the city has been restricted, thus restricting the promotion and application of emulsified asphalt sealant mixture; based on the research at home and abroad, cement is conducive to accelerating the formation of emulsified asphalt sealant mixture, but due to the excessive cement content, the mixture will crack. The mixing quality of cement is generally controlled within 3%, and the efficiency of accelerating the molding of the mixture is limited, and there is no research on the molding rate of the sealing layer mixture under the condition of high humidity.
