Abstract
The present invention has investigated a kind of novel emulsion asphalt Marshall method, belongs to field of road, suitable for the cold Marshall Test with mixture, feature be it is simple and convenient, operation is also relatively easy to.Currently, the index that the cold detection method with mixture in road surface determines not yet, and its technology path is also more complicated, needs specific test method and relevant technical parameter for the evaluation of Emulsified Asphalt Mixture.It can effective solution cold the problem of rubber cement is lost during hitting reality with mixture using diaphragm seal method；The adjustment of sequence is mixed and stirred, so that mixture hits real more closely knit, improves integral strength, while preferably having played the performance of a variety of materials performance during mixing and stirring；The curing time and method of Emulsified Asphalt Mixture are proposed, can guarantee that the performance of Emulsified Asphalt Mixture a variety of materials gives full play to.
Description
Technical field
The invention belongs to pavement test related fieldss, fit suitable for the marshall compaction of Emulsified Asphalt Mixture, while also
For the testing of materials relevant to emulsified asphalt.
Background technique
Among Emulsified Asphalt Mixture pavement system, hitting reality and maintenance problem always and do not have for Emulsified Asphalt Mixture
Unified standard, but playing the physical and mechanical property of a variety of materials as far as possible is main purpose, gives full play to the property of a variety of materials
The intensity of mixture can be allowed to reach best.
It is cold to be also referred to as half-flexible pavement with Emulsified Asphalt Mixture road surface, which is characterized in that cement and to gather materials and give mixing
While expecting enough rigidity, the addition of emulsified asphalt so that mixture but also with certain flexibility so that pavement system is hard and soft simultaneously
Ji.For bituminous pavement, improves intensity while also not losing flexibility, road-ability does not also weaken.Compared to
The cement pavement of rigidity, rigidity, which is lost, seldom but makes road surface have certain flexibility, reduces the generation of road surface through crack,
The repairing for reducing road surface also just reduces engineering economy loss.
The raising of emulsified asphalt slurry intensity is very useful for non-fragment orbit, various materials in Emulsified Asphalt Mixture
The performance for expecting performance is undoubtedly contributive to integral strength.In novel test method, the synthesis of various methods can be most
The overall performance for the raising Emulsified Asphalt Mixture changed greatly.
For this purpose, in engineering field and in the relevant field of emulsified asphalt, novel emulsified asphalt Marshall Test
Method is necessary.
Summary of the invention
The purpose of the present invention is customer service disadvantages of the existing technology, and it is mixed to provide a kind of simple, novel emulsified asphalt
Close material Marshall method.The purpose of the invention is achieved by the following technical solution:
The density measurement method of this compacting asphalt includes the following steps:
(1) sleeve of Marshall die trial is cleared up, lubricant is smeared in inside, pads upper filter paper in die trial bottom, later will be thin
Membrane cover enters the inside of Marshall die trial cylinder, forms a closed space.
(2) mixture weighing is mixed, the Asphalt emulsion content and suitable water calculated is weighed, by water and emulsified asphalt
After mixing and stirring about 30S, mixture is added and is mixed and stirred, mixing time about 30S, index is that mixture is uniformly mixed with emulsified asphalt.
(3) Emulsified Asphalt Mixture is filled among Marshall sleeve with appropriate tool, is around consolidated with tool.
The film of upside is put down after tamping, mixture is wrapped up in integrally and invests in film.After filter paper is added on the inside of the die trial of top, into
Row is two-sided to hit reality.It hits after finishing 12h in fact, Marshall sample is demoulded.
(4) after demoulding, surface film continues to cover, and carries out sprinkling maintenance or leaching for three days on end to mixture sample
Water curing, curing time are 28 days.
Emulsified Asphalt Mixture Marshall method of the invention compared with prior art, has the following advantages that and imitates
Fruit:
(1) easy to operate, and test equipment is easy；Test apparatus equipment and operating method without very complicated.
(2) due to emulsified asphalt and filling rubber cement have mobility, the method ensure that greatest extent emulsified asphalt and
Quality of rubber cement during mixing and stirring.
Film plays the role of sealing mixed material in maintenance processes, so that hydrated cementitious is more complete.
Detailed description of the invention
Fig. 1 is the schematic three dimensional views of invention new method.
Fig. 2 is the mixture intensity for inventing new experimental method and the relational graph of maintenance number of days.
Symbol description；1- filter paper；2- film
Specific embodiment
Technical solution in the embodiment of the present invention is stated, to be easier the understanding advantages of the present invention removed,
And then protection scope is further defined, embodiment:
Referring to Fig.1, new experimental method are as follows: lubricating oil appropriate is applied on the outside of Marshall die trial, bottom side is put into filter paper 1, so
Film 2 is put into die trial mold afterwards.Mixture is added among die trial after mixing and stirring, and the film 2 of upside is sealed, filter is put on top
Paper 1 later respectively hits die trial bilateral 50 times real.It is demoulded after putting 12 hours.During demoulding maintenance, two external films 2 continue to cover, and rise
To the effect of moisturizing, the aquation of cement can be made more abundant, to improve integral strength.
For mixing and stirring for Emulsified Asphalt Mixture, first have to stir emulsified asphalt and water, mixing time 30S, stirring
After add mixture and mixed and stirred, can prevent emulsified asphalt and mixture from first stir in this way can there are problems that agglomerating, right
It is unfavorable to play integral strength.Mixing time is respectively 30S, and die trial is added after mixing and stirring.
Referring to Fig. 2, when different materials mixture curing time difference, the intensity of material is not also identical, specifically.Maintenance 7
It when the intensity of different classes of material different classes of material when being below maintenance 28 days, this is because at curing time 7 days,
Internal cement and packing material do not play its chemical and physical properties completely.With the extension of curing time, material property hair
It waves sufficiently, certain Linear Amplifer trend is also presented in intensity, and backward at 28 days, intensity starts to tend towards stability, and determines thus best
Curing time be 28 days or so.
After emulsified asphalt demulsification, performance performance is substantially just completed.Due to the loss of water after forming process, cement
Aquation be it is incomplete, need certain watering just thus come to guarantee the abundant aquation of cement, specific embodiment be molding 24
Every 12 hours sprinkling maintenances are primary or progressive flooding maintenance after hour.3 days curing cycles, this maintenance method can be maximized
Play emulsified asphalt and cement physical and chemical performance.
This embodiment only covers a part of the characteristics of inventive method and range on probation, the related skill of any couple of present invention
Art feature and method are copied, and protection scope of the present invention should be all covered by.
