Technical Field

[0001] The utility model relates to the technical field of road maintenance construction, in particular to a paving device. Background Art

[0002] Micro surfacing is a preventive maintenance method developed on the basis of slurry seal. Micro surfacing usually uses a certain proportion of stone chips or sand, fillers, polymer-modified emulsified asphalt, admixtures and water as raw materials. After the raw materials are stirred into a fluid mixture, they are evenly spread on the road surface to obtain a seal. The construction process of micro surfacing is relatively complex and has a high technical content. It is mainly suitable for urban roads, landscapes, parking lots and other sections. It is necessary to adapt the proportion of raw materials according to the driving and climatic conditions of the specific construction section to obtain a seal suitable for the construction section. Quality control is required during the paving process to ensure the construction quality of the colored micro surfacing and improve its color durability and service life.

[0003] During the construction of color micro-surfacing, paving equipment will be used. Traditional paving equipment includes a control console, a mixing tank, a paving box, and several silos for storing raw materials.
