Roadway road foundation filling composition and preparation method thereof

Abstract

The invention belongs to the technical field of concrete materials, and in particular relates to a roadway road foundation filling composition and a preparation method thereof. The composition includes by mass: 32.5- 47.8% of a binder, 63.3- 82.4% of a coarse aggregate, 32.2- 44.5 of a fine aggregate, 10.6-18.4% of gypsum, 4.5-8.7% of fatty alcohol polyoxyethylene ether sulfate sodium, 12.3-17.5%of polyvinyl chloride cement, 3.8-7.6% of a cellulose fiber, 4.4-9.7% of citric acid, 5.2-8.3% of tartaric acid, 2.7-6.5% of aluminite, 5.4-10.8% of quicklime, 3.3-7.2% of magnesium oxide, 1.2-5.5% of kyanite, 4.6-9.6% of calcium chloride, 4.8-8.2 % of ethylene glycol and 45.7-82.6 % of water. The roadway road foundation filling composition has the advantages of easy water seepage, freezing resistance, slow condensing speed and convenient transportation.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a vehicle road subgrade filling composition, a preparation method and a use method thereof. Background technique [0002] The vehicle road subgrade filling composition in the prior art is mainly filled with soil and sand and gravel, and some directly add cement to make concrete from the soil and sand and gravel. Poor, especially in terms of water seepage performance, especially in the roadways of urban roads. When the rainfall is obviously too much, the sewers in the city cannot completely drain the accumulated water on the roadways in time. If the base of the roadway has good water seepage performance, it can help the sewer to discharge accumulated water to a certain extent, and at the same time avoid traffic accidents caused by the accumulation of water in low-lying and uneven places on the road surface of the roadway. [0003] In addition, the concrete materials ...

[0002] The vehicle road subgrade filling composition in the prior art is mainly filled with soil and sand and gravel, and some directly add cement to make concrete from the soil and sand and gravel. Poor, especially in terms of water seepage performance, especially in the roadways of urban roads. When the rainfall is obviously too much, the sewers in the city cannot completely drain the accumulated water on the roadways in time. If the base of the roadway has good water seepage performance, it can help the sewer to discharge accumulated water to a certain extent, and at the same time avoid the occurrence of traffic accidents caused by the accumulation of water in low-lying and uneven places on the road surface of the roadway

[0003] In addition, the concrete materials currently used to fill the base of the roadway set up very quickly, and the concrete materials that need to be filled with the base of the roadway can only be prepared at a place very close to the construction site, which will cause great damage to the environment around the construction. Influence; if the distance is long, use vehicles to transport, and because the concrete material sets very fast, the concrete has been semi-set or even completely set and cannot be used for construction
