Medium temperature pitch mixture batching plant and method for preparing mixture by utilizing batching plant

Abstract

The invention discloses a medium temperature pitch mixture batching plant and a method for preparing mixture by utilizing the batching plant. The set of equipment comprises a raw material warehouse part, a batching plant part, a finished product heating part and a product storing part which are connected through conveying belts, pipelines, gates and the like, wherein the raw material warehouse part mainly comprises a plurality of collecting bins for storing materials with different particle sizes, and the collecting bins are connected with a receiving hopper through one or more material conveying belts; the batching plant part mainly comprises the receiving hopper, a batching bin and a half-finished product transition bin; the finished product heating part mainly comprises a finished product heating bin, a dust removal system, a heater, a wind power control system and a finished product transport vehicle; and the product storing part mainly comprises a finished product transport vehicle, a finished product transport vehicle track and a plurality of finished product storing bins. The medium temperature pitch mixture prepared by the batching plant disclosed by the invention has a wider construction temperature range and can be constructed under the climatic condition of not lower than -5 DEG C.

Description

technical field [0001] The invention relates to the preparation technology of asphalt mixture in the field of road engineering, in particular to a medium-temperature asphalt mixture mixing building, and also relates to a method for preparing mixture by using the mixing building. Background technique [0002] With the rapid development of urban infrastructure construction, the demand and requirements of urban road traffic are getting higher and higher. Under the combined effect of traffic load and climate influence, asphalt pavement will gradually deteriorate in pavement condition and service capacity as time goes by. In recent years, the rapid economic development has brought about a rapid increase in traffic volume, large-scale vehicles, and serious overloading, which has brought about a series of diseases, such as rutting, cracking, wrapping, looseness, subsidence, and potholes. In order to maintain the good performance of the pavement and prolong its service life, differ...

AI Technical Summary

Problems solved by technology

In actual construction, the scale of the repair project is generally small, and the amount of maintenance is also small, and the amount of some pits is less than 1 ton

The cost is higher due to the more expensive asphalt used in the cold patch

However, the stability of cold-patch asphalt mixture is generally lower than 5kN, and it is difficult to meet the requirement that the strength of asphalt mixture for road surface is not less than 8kN

[0013] Therefore, hot mix asphalt mixture has long-standing problems of high energy consumption and low efficiency; and low-level, repeated maintenance and congestion problems; at the same time, long-standing pollution emissions and health hazards to maintenance workers

On the other hand, cold-patch asphalt mixture cannot meet all construction needs

[0014] Urban road maintenance materials and technology are always unresolved problems, but so far no satisfactory technical solutions have come out
