Abstract
The invention discloses asphalts, it is characterised in that：Including asphalt and strengthen skeleton, it is to use latticed skeleton made of Basalt fiber composite rib to strengthen skeleton, and the asphalt includes pitch, rubble, mortar, continuous basalt fiber and carbon dust, pitch：29 ~ 45 parts；Mortar：15 ~ 45 parts；Continuous basalt fiber：35 ~ 60 parts；Carbon dust：7 ~ 15 parts.Surface evenness of the present invention is good, will not leave track, eliminates the security risk that track is brought.
Description
Technical field
The invention belongs to road and bridge construction field more particularly to a kind of asphaltic road-mix surface courses for being used to be laid with highway.
Background technology
There are bituminous paving and cement pavement in the road surface of highway either avenue highway, and bituminous paving is to tire
It rubs small, but to hot day by thermal softening, automobile rolls and forms track later, pitch is bonded on tire, first, easily causing
Traffic accident, but tire is damaged larger.And cement pavement is big to the friction of tire, it is big to the abrasion of tire, and cost
It is higher.
Therefore, mostly using asphaltic road-mix surface course, existing asphalt presses knot used on the road surface being laid with now
It is different to close material, asphalt and coal tar pitch two major classes can be divided into；Also there are use in some countries or mix natural drip
Blue or green mixing.It is that rubble can be divided into, gravel, chiltern, slag several classes of by kind difference used of gathering materials, it is used with rubble
It is the most universal.It is different by mixture maximum particle size, coarse grain (less than 35~40 millimeters), middle grain can be divided into（20~25 millimeters
Below）, particulate (less than 10~15 millimeters), sand grains (less than 5~7 millimeters) etc. it is several classes of.It is different by the compaction rate of mixture,
It can be divided into that close-graded, half open gradation and open gradation etc. are several classes of, and open mix is also referred to as asphalt macadam.It is wherein hot to mix the close of heat paving
Graded broken stone mixture is durable, and intensity is high, and good integrity is the representative materials for building advanced bituminous paving, applies
It is most wide.There are different specifications in various countries to bituminous concrete formulation, and the heat that China formulates mixes hot black top mixture technical specification, with
Voidage 10% and following person are known as bituminous concrete, are subdivided into I type and II type, the porosity of I type is 3 (or 2)~6%, is belonged to
Level of confidentiality distribution type；II type is 6~10%, belongs to half open gradation type；More than 10% person of voidage is known as asphalt macadam, belongs to open gradation type.
Modified pitch also including modified asphalt mixture, refers to " admixture rubber, resin, high molecular polymer, levigate
The outer-penetrating agents such as rubber powder or other fillers (modifying agent) are taken to measures such as pitch mild oxidation processing, make pitch or pitch
The performance of mixture is improved and manufactured asphalt binder ".Modifying agent refers to " add in pitch or asphalt
Natural or artificial organic or inorganic material, it is fusible, be dispersed in pitch, improve or improve bituminous pavement property (with drip
Green grass or young crops reacts or wraps in surface of aggregate) material ".The quality of modified effect is mainly carried out with modified pitch index
Evaluation, the evaluation index of modified pitch are：(1) Susceptibility Indexes：Penetration index (needle penetration).(2) cryogenic property index：5
DEG C ductility and equivalent brittle point.(3) high temperature performance index：60 DEG C of viscosity, softening point and equivalent softening point.(4) thermal stability is (resistance to old
Change) index：Rotary thin film in drying oven is tested.(5) pitch viscoelastic effect index：Elasticity is recovered.6. asphalt and aggregate bond stress index：
Viscous toughness test.7. construction and safety index：Flash-point, 135 DEG C of kinematic viscosity.8. isolate index：Softening point difference.
All there are following defects for above-mentioned existing asphalt：
Low temperature resistant and high temperature resistance is poor, and the cryogenic conditions for the north are small, and easily embrittlement is crusted on road surface, asphalt arch
It rises, loses surface evenness, the area of exposure in sunshine, asphalt softening, in fact it could happen that road are being chronically at for south
The defects of face pitch thickness differs, causes road surface uneven.
The content of the invention
In order to overcome above-mentioned various asphaltic road-mix surface courses there is high temperature resistant, resistance to low temperature is poor the defects of, this
Invention provides asphalt, which is with the addition of basalt fibre, enhances the intensity of asphalt and resistance to
High temperature and low temperature resistant performance, can be chronically in exposure in sunshine and be used in ice and snow weather, scope of application light, use
Long lifespan.
Asphalt, it is characterised in that：Including asphalt and strengthen skeleton, it is to use basalt fibre to strengthen skeleton
Latticed skeleton made of composite reinforcing, the asphalt include pitch, rubble, mortar, continuous basalt fiber and carbon dust,
In terms of parts by weight：
Pitch：29 ~ 45 parts
Mortar：15 ~ 45 parts
Continuous basalt fiber：35 ~ 60 parts
Carbon dust：7 ~ 15 parts.
Continuous continuous basalt fiber be basalt building stones after 1450 DEG C~1500 DEG C meltings, pass through platinum-rhodium alloy wire drawing
The continuous fiber that bushing high speed pulling forms.Similar to glass fibre, performance is between high intensity S glass fibres and alkali-free E glass
Between glass fiber, the color of pure natural continuous basalt fiber is generally brown, some are like golden.
The asphalt, including pitch, rubble, mortar, continuous basalt fiber and carbon dust, in terms of parts by weight：
Pitch：55 ~ 75 parts
Mortar：74 ~ 98 parts
Continuous basalt fiber：22 ~ 35 parts
Carbon dust：15 ~ 25 parts.
The present invention has the following advantages：
The present invention adds continuous basalt fiber in asphalt, come improve the intensity of asphalt, high temperature resistant and
The exposure of low temperature resistant performance, either northern ice and snow weather or the southern sun, will not all destroy made of the present invention
Road surface, surface evenness is good, will not leave track, eliminates the security risk that track is brought.
