Problems solved by technology

(JTGF40-2004) Technical Specifications for Highway Asphalt Pavement Construction stipulates that when paving in multiple layers, the next layer should be open to traffic for at least 24 hours before the upper layer can be paved. Not only will it have a great impact on road traffic, but it will also cause great economic losses.

Abstract

The invention provides an MS-7 modified emulsified asphalt slurry mixture for rutting repair on asphalt pavement, which includes aggregate, modified emulsified asphalt and water, wherein the modified asphalt in the modified emulsified asphalt accounts for 10% of the total weight of the aggregate 5~7%, the total water accounts for 4~10% of the total weight of the aggregate, the nominal particle size of the coarsest stone is 30mm, and the thickness of a single layer is 30mm. Since the present invention realizes one-time closed traffic repair for the ruts with a depth of 25 mm to 30 mm on the same road section, the process is simplified, the road surface rut repair period is obviously shortened, the construction cost can be reduced, and the vehicle traffic efficiency can be improved; In addition to rut repair, it can also be used as a protective layer, wear layer or noise-proof layer for new road surfaces, bridge deck pavement, preventive maintenance of existing road surfaces, simple pavement for local or temporary roads, landscaping or noise prevention, etc. ; Due to the strong anti-rutting ability of the present invention, it can effectively avoid repeated appearance of ruts.

Description

Technical field: [0001] The invention relates to a material used for asphalt pavement rut repair, in particular to an MS-7 modified emulsified asphalt slurry mixture for asphalt pavement rut repair, which can prevent repeated occurrence of ruts, shorten the construction period of road rut repair, and reduce engineering costs. Background technique: [0002] The vast majority of expressways and ordinary roads in my country are asphalt pavement. Rutting has become one of the main diseases of asphalt pavement due to factors such as severe overloading of vehicles, large traffic volume, channelized driving, and high temperature weather. According to statistics, 80% of asphalt pavements have rutting to varying degrees. Ruts with a depth of less than 12.5mm have little impact on driving safety and generally do not need to be treated; ruts with a depth greater than 12.5mm that affect driving safety require treatment. Repairing ruts with micro-surfacing is a more scientific and econom...
