Description

Slurry mixture mixes and stirs test instrument

Technical field

The utility model belongs to the instrument or the auxiliary equipment technical field of manufacturing or spreading paving material, is specifically related to slurry mixture and mixes and stirs test instrument.

Background technology

Along with China's rapid economic development, the mileage of highway in China is in continuous increase, and asphalt concrete pavement is because its planarization is good, and it is steadily comfortable to drive a vehicle, and noise is low, and many countries all preferentially adopt when building highway, and China is no exception.In expressway construction and maintenance processes, emulsified asphalt slurry seal technology and little table place technology play an important role.

Emulsified asphalt slurry seal is that aggregate, water, filler, the stabilizing agent with emulsified asphalt and certain grating adopts evenly pave a kind of supercrust on roadbed or the road surface of artificial or mechanical agitation.It can make aging, crackle, disease smooth, loose, the hollow bituminous paving be repaired again, can significantly improve the waterproof, antiskid of bituminous paving, performance such as smooth, wear-resisting.No matter be to the old asphalt pavement or the bituminous paving of new making, low-grade highway or high-grade highway, urban road still are that country road etc. all can adopt less asphalt material, and fast speeds is improved road conditions rapidly.At present, emulsified asphalt slurry seal is mainly used in the newly-built of common road bituminous paving and maintenance, further applies at the newly-built of highway and maintenance.

In recent years, succeed in developing Modified Slurry Sealing again on the basis of common slurry seal, mix high molecular polymer the common emulsified asphalt material is improved, this modified emulsified asphalt slurry seal is called as " surperficial meticulous punishment ", is called for short at " little table place ".Little table place adopt special equipment with the polymer modification emulsified asphalt, gather materials, filler, water mix and stir into slurry mixture according to a certain ratio with additive and the former road surface that paves rapidly on, but after paving within a short period of time open to traffic laminate structure, little table place has been considered to one of effective, the most most economical means of repairing road rut and other multiple pavement disease, get the nod in China, and promotion and application gradually.Little table place is mainly used in water resistance and the anti-wear performance that improves top course, also is used to fill up the rut of bituminous paving and the disease of Reparation of Bituminous Pavement, as crackle, peel off and wear out etc.In China, also little table place is used for newly building the following seal of road to strengthen the water resistance of road.Little table place adopts reasonable raw material proportioning and construction method, can prolong 4～7 years service life of asphalt roads, is adapted to the high-grade asphalt roads of high vehicle flowrate and the making of urban road especially.

Slurry seal and little table need tentatively to determine rational slurry mixture proportioning before being in construction, and with this foundation as the construction measure control, need carry out series of laboratory tests, mixing and stirring test is wherein an important content, but its objective is mixing time and the pulping state of determining slurry mixture, but the mixing time is meant that compound adds emulsified asphalt and begins to be stirred to compound and mix time till motionless, it is the process of mixing and stirring of simulation modification slurry mixture, in order to determine modification slurry mixture breakdown of emulsion operational use time before, and, determine the kind of additive and use number by this test as the important evidence that mix material proportioning designs.The test method of regulation is with manually stirring in " highway engineering pitch and asphalt testing regulations ", but in whipping process, determine the mixing time according to feel and range estimation, just unavoidably there is the influence of subjective factor in this, test for same raw material proportioning, the result of same individual twice test is not necessarily identical, different people's alr modes, firmly, observe all inequality, the result who obtains is also inconsistent, can not provide more objective experimental data for the making slurry seal.

Summary of the invention
