Description
Technical field
The invention belongs to road engineering technical field, especially relate to a kind of BUTON rock asphalt modified asphalt mixture heating
Mix and stir processing technology.
Background technology
The production process of BUTON rock asphalt modified asphalt mixture be by gathering materials, Colophonium, kir and breeze etc. are by necessarily
Ratio mix and stir, obtain hot-laid mixture, major function is to improve the high-temperature behavior on road surface and water stability, improves road with this and uses
Performance, to meet the demand of traffic loading and climatic environment.Due to BUTON rock asphalt stable performance, ageing resistance is strong, and easily
It is dissolved in matrix pitch so that it is modified asphalt mixture has that production technology is simple, performance prominent, the feature of use easy to spread.
Currently used kir routine mixes and stirs technique, the most first will heating after gather materials and the kir under room temperature is being mixed
Mixing and stirring in cylinder, then the Colophonium after heating is added to mix and stir in cylinder and mixed and stirred, add breeze the most again, present in it, problem has:
(1) heating of kir needs to rely on and gathers materials and the conduction of heat of matrix pitch, then kir could with gather materials, matrix pitch body
System merges, but within the limited mixing time, only rely on gather materials, the kir of matrix pitch conduction of heat heating may reach
Less than the optimum temperature playing modifying function；(2) do not account for thickness to gather materials and the difference of kir adsorptive pitch ability, cause
It is different that the Colophonium that thickness is gathered materials wraps up in attached situation, and then has influence on the compacting of compound, just need to increase drip for reaching objective air void
Blue or green consumption, causes the waste of Colophonium resource, reduces the economy of BUTON rock asphalt modified pitch.Therefore, according to BUTON rock asphalt
Feature improve existing technique of mixing and stirring necessary, propose kir mixed material heating for this and mix and stir technique.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of BUTON rock asphalt to change
Property asphalt mixture heating mix and stir processing technology, with obtain Colophonium wrap up in attached uniformly, stable performance, meet hot-mix asphalt mixture
Can requirement, good economy performance, mix and stir production technology simple BUTON rock asphalt modified asphalt mixture.
The purpose of the present invention can be achieved through the following technical solutions:
Processing technology is mixed and stirred in a kind of BUTON rock asphalt modified asphalt mixture heating, the method employing following steps:
(1) will gather materials and carry out adding stand-by heat；
(2) join in step (1) products therefrom after Colophonium being heated and mix and stir；
(3) kir is joined in step (2) products therefrom mix and stir；
(4) breeze is joined in step (3) products therefrom and mix and stir；
(5) temperature of rate-determining steps (4) gained compound, it is thus achieved that BUTON rock asphalt modified asphalt mixture；
Kir described in step (3) is heated to 80～110 DEG C before joining step (2) products therefrom.
As preferred embodiment, kir is heated to 90 DEG C.
Gather materials for limestone, basalt or diabase described in step (1), utilize mixing station to be heated to 180～200
DEG C, or utilize indoor small to mix pot heating, controlling to mix and stir temperature is 165～175 DEG C.
Colophonium described in step (2) is 70# matrix pitch, SBS modified pitch or other label matrix pitch, is heated to
155～170 DEG C.Utilize mixing station to mix and stir 25～30s, or utilize indoor small to mix pot to mix and stir 90～110s.
Step (3) utilizes mixing station mix and stir 5～10s, or utilize indoor small to mix pot to mix and stir 60～90s.
Breeze described in step (4) is limestone mineral powder, is heated to 165～175 DEG C.Utilize mixing station mix and stir 22～
32s, or utilize indoor small to mix pot to mix and stir 90～110s.
The temperature of the compound described in step (5) controls at 155～175 DEG C.
Described gather materials, the weight ratio of Colophonium, kir and breeze is 100:3.5～5.0:1～3:1～3.
Compared with prior art, the invention have the advantages that
The method of the present invention is by heating kir in advance, and in sequence add gather materials, Colophonium, kir and
Breeze, carries out the preparation of processes of rock asphalt modified asphalt compound: kir can improve itself and matrix pitch by heating in advance
Adhesive capacity, gives full play to kir modifying function, and the water resistant improving kir compound damages performance, high temperature anti-rut behavior
And crack resistance at low-temperature, and using room temperature kir to make kir compound, it is good that its performance can not show a candle to heat kir；Add
Order adds kir after changing into being initially charged Colophonium, it is considered to difference is gathered materials and wrapped up in the feature that attached situation is different from Colophonium, is effectively improved
The thickness Colophonium that gathers materials wraps up in attached uniformity, and compound is prone to compacting, and performance is improved.
The creativeness that the present invention is the most prominent is that, adds kir and is first preheating to 80～110 DEG C, if kir temperature
Too low, its asphalt component is likely not to have fully activation, affects it attached with wrapping up in of gathering materials；And if temperature is too high, it is likely that lead
Cause ageing of asphalt and affect its performance.
The method of the present invention needs increase kir heating steps and change the adding order of Colophonium and kir, more conventional
For mixing and stirring technique, total mixing time in production process of mixing and stirring of whole compound can keep constant, and existing batching plant only needs
Increase kir firing equipment or use hot recycling equipment.
The more conventional technique of method of the present invention can promote the adhesiveness of kir and wrap up in attached effect, improves kir modified
The compactness of asphalt, and improve its pavement performance, can be used for the making of each surface layer of bituminous paving, there is obvious economy
And social benefit.
The method of the present invention have be easily achieved, mix and stir technique simply efficiently, compound be prone to the features such as compacting, can be more preferably
Play the modifying function of BUTON rock asphalt.
