Abstract

The invention is specifically a noise-reducing micro-surface with high shear strength and a preparation method thereof, which solves the problems of poor shear strength and high noise in the existing micro-surface. It is composed of the following raw materials in parts by mass: 30-35 parts of emulsified rubber asphalt; 20-25 parts of self-emulsifying epoxy resin emulsion; 5 parts of polyoxyethylene rosin acid; 2 parts of monoglyceride; 15-45 parts of water; 345 parts of graded crushed stone, 6 parts of cement; 2 parts of slaked lime. The micro-surface of the present invention has high elongation at break, good ductility, good fatigue resistance, high bonding strength, and stones are not easy to fall off; and while improving the ductility of epoxy resin, it can also form an integrated Cross-linked structure; at the same time, it promotes the degradation of waste rubber powder, improves the storage stability of the two emulsions, prolongs the demulsification time and increases the operating time.

Description

technical field [0001] The invention relates to the field of road repair and maintenance, in particular to a noise-reducing microsurfacing with high shear strength and a preparation method thereof. Background technique [0002] With the gradual completion of the construction of expressways in our country, most expressways have entered the initial maintenance stage. A large number of expressways have micro cracks in the early stage, and some expressways have already had serious ruts due to their heavy traffic volume. In order to solve the above problems At present, the face-to-face treatment technology of micro-surface is widely used, which not only solves the problem of water seepage in fine cracks, but also solves the problem of local rutting. [0003] The current micro-surfacing is mainly constructed with slow-cracking and fast-setting emulsified asphalt plus SBR latex modifier and some fillers. The emulsified asphalt modified by SBR latex essentially utilizes the good du...
