Description
Technical field
The present invention relates to a kind of quick environment protection pavement bases, and in particular to a kind of quick environment-friendlyroad road based on regenerated plastics
Face.
Background technology
Cement concrete road mainly builds base, generally existing material using the material with higher elasticity modulus at present
Procurement cost is high, transport difficulty is big, and operational procedure is complicated, occupies the problems such as long in time limit.Simultaneously because different regions roadbed dry and wet
The difference of type and highway loading situation, base material and structure design do not have strict standard.Usually require engineering staff according to
Construction State calculate and verify repeatedly, the unstable of roadbase quality is objectively resulted in, to influence road
Ability.
Cement concrete pavement high, stability and the good road surface types of durability as a kind of intensity, in all kinds of road works
Extensive use is received in journey, is to build up one of maximum road surface types of area at present.But since cement concrete pavement is to row
The specific requirement of the environmental factors such as water condition, foundation base intension, monolithic stability degree generally requires to build in advance below top course
Base, for preventing the road diseases such as purt mud, frost, Water Damage, while reduce roadbed top surface compression, improve pavement structure hold
Loading capability provides conveniently for surface construction.
In constructing at this stage, lean concrete, bituminous concrete, cement stabilized macadam, lime-flyash stabilization are mainly used
The traditional building materials such as rubble build base.Lean concrete is formulated by thick, fine aggregate and certain cement and water
A kind of material, intensity are more than semi-rigid sub-base material；Bituminous concrete refers to the mineral aggregate for having certain gradation composition, rubble etc.
With a certain proportion of bitumen for road use material, the mixture made of mixing under stringent control condition, strength of materials height, globality
It is good；Cement stabilized macadam is to make aggregate with graded broken stone, simultaneously using the gap of cementitious material and enough grey slurry filler aggregates
It paves compacting by embedded squeezing principle, there is ideal intensity, impermeability and frost resistance；Pulverized limestone.Flyash stabilization gravel be by lime,
Flyash is with other incorporation materials (soil gathers materials) by proper proportion, optimum moisture content, reasonable process (mix, compacting and maintenance)
Manufactured mixture.
At this stage cement concrete pavement base layer construction mainly use lean concrete, bituminous concrete, cement stabilized macadam,
The materials such as lime-flyash stabilization rubble, there is material cost height, transport difficulties to varying degrees greatly, structure design
Difficult, the problems such as construction standardization degree is low, resources circulation is poor.Specifically, lean concrete base due to its cementitious matter content is few,
Porosity is larger, and water resistance is poor, cannot obstruct road table and be seeped into base and partition underground capillary water rising under water；Pitch coagulation
Soil material higher price, complicated construction technique are mainly used for advanced road construction；Cement stabilized macadam needs time health,
It is unsatisfactory for the rapid construction requirement of road；Lime-flyash stabilization crushed stone material derives from a wealth of sources, but mechanical property is general, Zhi Nengman
Sufficient inferior grade roadbase requirement.
Thermosetting property SAN foamed plastics is a kind of heat cured foamed plastics, and material of main part is that styrene-propene is cured total
Polymers (Styrene Aery lonitrile Copolymer, SAN).SAN can be used for various resin systems, be suitable for various knots
Composition type and technique；Hole-closing structure does not absorb water；Low Resin Absorbent amount；Density is between other cystosepiments and plank；
In forming process thermal stability it is fabulous up to after 150 DEG C without swelling；Warm nature is thermoformable up to 127 DEG C；High temperature resistant, tool
There is high chemical constituent stability；There is higher toughness and high abrasion capacity compared with the cystosepiment and plank of crosslinking formula；
Splendid anti-fatigue performance and creep-resistant property；Splendid chemical stability；High compression-strength and compression mould are dizzy；Shock resistance
It is good.SAN mainly as a kind of large-scale high performance structures sandwich foamed material, is widely used in the necks such as wind energy, transport, shipping at present
The large-scale high performance structures in domain are built.But it will produce a large amount of SAN foams wastes, needle in the preparation process such as processing, cutting
High added value, the recycling method of high usage are lacked to the waste.
SAN foamed plastics belongs to the leftover bits and pieces in process of manufacture, average thin for the powder that bulk material is cut down
Spend 40 mesh.Waste plastic regeneration, which utilizes, at present mainly chemistry or heat chemistry, energy regenerating method, physiochemical mutagens method etc..Chemistry or
Although heat chemistry recycling can make waste plastics be decomposed into industrial chemicals, liquid fuel or obtain having changing for other application performance
Property material, but industrialize in general more difficult, need more harsh reaction condition, and production cost high to equipment requirement
It is high.Simultaneously SAN as a kind of density small, bulky foamed plastics, to solvent and other reactant demands in reaction process
It is excessive, greatly improve regeneration cost；Although energy regenerating method can by burn technics of reclaim of plastic waste part energy, by
Contain a large amount of additives and fire retardant in SAN foamed plastics itself, easily causes secondary pollution in combustion.Physiochemical mutagens
Method process is simpler, and the requirement to equipment is relatively low, is the most recovery method of economy and operability under the conditions of the prior art.
But without the finished product application of the high additional output value, meagre commercial profit constrains to be replanted current SAN foamed plastics physiochemical mutagens methods
The development and application of method, therefore a kind of environment protection pavement base based on SAN foamed plastics can be developed, to realize SAN foams
The recycling of plastics, avoids existing for cement concrete pavement base at this stage that material cost is high, transport difficulty is big, structure design
Difficult, the problems such as construction standardization degree is low, resource circulation utilization is poor.
Invention content
It is an object of the invention to overcome the above-mentioned prior art, a kind of quick ring based on regenerated plastics is provided
Road surface is protected, which can realize the recycling of SAN foamed plastics, while have that the cost of material is low, convenient transportation, structure design
Simply, the feature that construction standardization degree is high, resource circulation utilization is preferable.
In order to achieve the above objectives, the quick environment protection pavement of the present invention based on regenerated plastics includes that roadbed, cement are mixed
Solidifying dirt road supercrust, several SAN regenerated plastic boards and several interlayer securing devices, wherein each SAN regenerated plastic boards are located at
Between roadbed and cement concrete road face layer, each SAN regenerated plastic boards are sequentially distributed, and adjacent two blocks of SAN regenerated plastics
