Technical Field
The invention belongs to the technical field of asphalt pavement detection, and particularly discloses an asphalt pavement water permeability coefficient sealing material and a construction method thereof.
Background
With the rapid development of economy and society in China, the proportion of asphalt pavements in expressways is very large, and a plurality of diseases occur simultaneously, wherein the most typical early damage of the asphalt pavements is related to water basically and is mainly caused by water seepage of the asphalt pavements. The water permeability of asphalt pavement is an important standard for measuring the quality of pavement. The water permeability coefficient is an index for visually reflecting the water permeability resistance of the asphalt pavement, and reflects the speed of water flowing in the surface layer structure and the porosity and connectivity in the surface layer structure, and has a plurality of influence factors.
In the conventional asphalt pavement water permeability coefficient test, the annular sealing area is sealed by using sealing materials such as glass putty, plasticine and the like, and the sealing materials are not required to enter the inner ring, and then a strip-shaped sealing material which is twisted into a thumb is piled in the center of the annular sealing area and is piled into a circle. However, the sealing materials are not well bonded with the asphalt pavement and are easy to seep, and the sealing materials such as glass putty, plasticine and the like are soft and are not easy to form and have poor impermeability, so that the sealing materials are difficult to clean when being adhered to the asphalt pavement or the instrument base.

Further, the preparation method of the component B comprises the following steps: pouring the cement, the mineral powder and the silicon powder into a container in proportion, adding water in proportion, stirring uniformly, adding the liquid setting accelerator in proportion, and continuously stirring uniformly.
The invention also provides a construction method of the asphalt pavement water permeability coefficient sealing material, which comprises the following steps:
