Embodiment 1

[0019] The emulsifier used in Example 1 is the lignin amine emulsifier KLQAS. Weigh 90 parts of stone according to the gradation, add 2% sulphoaluminate fast hardening cement, add 0.2% polyvinyl alcohol fiber and 0.2% mortar king, add 12% tap water, stir the aggregate evenly, add 8% emulsified asphalt, Stir quickly evenly, and prepare the corresponding test specimens.

Embodiment 2

[0020] The emulsifier used in Example 2 is the lignin amine emulsifier KL-F-DETA. Weigh the stones according to the gradation, add 4% sulphoaluminate fast hardening cement, 0.3% polyvinyl alcohol fiber and 0.3% mortar, add 10% tap water, and mix the aggregate evenly. , Add 6% emulsified asphalt in the total mixture, mix quickly and evenly, and prepare corresponding test specimens.

Embodiment 3

[0021] The emulsifier used in Example 3 is the lignin amine emulsifier KLQAS. Weigh the stones according to the gradation, add 2% of the total mixture of ordinary Portland cement number 425, add 1% of the cement mass of sodium sulfate, add 0.2% and 0.2% of the mixture of polyvinyl alcohol fiber and Mortar King, add 11% tap water, mix the aggregate evenly, add 4% emulsified asphalt, which accounts for the total amount of the mixture, mix quickly evenly, and prepare the corresponding test specimens.

Abstract

The invention belongs to the technical field of emulsified asphalt and particularly relates to an emulsified asphalt mixture and a preparing method thereof. The emulsified asphalt mixture is prepared from, by mass, 4-8 parts of emulsified asphalt, 2-15 parts of water additionally added, 85-95 parts of stone and 0-6 parts of filler. The filler is one or more of Portland cement, coagulant, fiber, plasticizer, aluminum sodium sulfate high early strength cement, aluminum oxide and zinc oxide. Compared with the prior art, by adding the fiber and the plasticizer into the emulsified asphalt mixture to which the cement is added, the purpose of improving flexibility of the cement emulsified asphalt mixture is achieved; meanwhile, the requirement for quick opening to traffic of construction is met; in addition, amphoteric oxide, the cement, the fiber and the plasticizer in the emulsified asphalt mixture can ensure quick opening to traffic; meanwhile, properties such as road surface strength, flexibility and water damage resistance are given into consideration.

Description

Technical field [0001] The invention belongs to the technical field of emulsified asphalt, and specifically relates to an emulsified asphalt mixture and a preparation method thereof. Background technique [0002] Emulsified asphalt does not require heating and can be constructed at room temperature. It overcomes the shortcomings of traditional hot-mixed asphalt that waste energy, pollute the environment and the asphalt is easy to age during mixing. It conforms to the development concept of modern society to save energy and protect the environment and become the future development of road paving materials. main direction. In recent years, emulsified asphalt has been widely used in highway pavement maintenance, such as micro-surface, slurry seal and cold recycling construction of asphalt mixture. There are still many problems with emulsified asphalt in construction applications, such as poor storage stability, which makes it difficult to preserve the emulsion; uneven mixing with t...
