Loose bauxite mineral aggregate；Finally, carrying out fencing lawn according to environment temperature to Friction Surface, being opened after road surface is fully cured
Put traffic.
Preferably, then the laitance first on the table of mechanical removal road, greasy dirt, graticule are directed to in-service cement pavement, using spray
Ball or blasting treatment unseal and remove the discrete material and sundries of road table, remove road table using steel wire rotary brush for bituminous pavement
Discrete material and sundries finally complete cleaning and drying using vacuum cleaner.Using the asphalt mixtures modified by epoxy resin being composed of A, B component
Rouge binder is continuous, do not stop, equably spread to treated road surface, the dosage of epoxy adhesive are 1.20kg/
m2~1.85kg/m2, thickness is 1.3mm~1.7mm；After epoxy adhesive spread is uniform, bonded immediately in epoxy resin
Bauxite mineral aggregate is dispensed in agent, the dosage of bauxite mineral aggregate is 7.32kg/m2~10.74kg/m2。
Compared with prior art, the present invention has following the utility model has the advantages that the upper surface of pavement structure layer is by bauxite ore
Material is made, and bauxite mineral aggregate is big as the hardness gathered materials, and polishing value is twice or so commonly to gather materials, and wearing valve is used less than 4
This, which gathers materials, can be improved the anti-slide performance on road surface as pavement structure layer material, reduces the degree of pavement abrasion, extends road surface
Antiskid performance.Layer is epoxy adhesive below pavement structure, and the construction process of the pavement structure is simple, required to apply
Work mechanical equipment is simple, and the construction time is short, and the close traffic time is short, compared with previous pavement structure, has apparent advantage.
Specific embodiment
The present invention is described in further detail combined with specific embodiments below.
Pavement structure of the invention has that antiskid, wear-resisting, easy for construction, required mechanical equipment is simple, traffic off-period
The advantages such as short.The Friction Surface is laid on in-service bituminous pavement or cement pavement, is made of double-layer structure, upper layer by
The wear-resisting bauxite mineral aggregate composition of antiskid, cutting optimal is epoxy adhesive, and epoxy adhesive is prepared by A and B component
It forms.
Pavement structure Friction Surface of the present invention is in construction, the original road surface of first processing, is carried out using vacuum cleaner clear
Reason and drying, two measured portions of epoxy adhesive A and B are mixed evenly, and spread paves in processed road table
It is even, bauxite mineral aggregate is dispensed immediately, and according to environment temperature, fencing lawn is carried out to Friction Surface, it is right after road surface is fully cured
Friction Surface is cleaned, can open to traffic after the extra and loose mineral aggregate of removing Friction Surface.Wherein, bauxite mineral aggregate
The component of aluminum oxide is greater than 88%, and clinker is made by rotary kiln calcining by bauxite.
The quality requirement of bauxite mineral aggregate are as follows: Mohs' hardness is 8~9, and polishing value is greater than 70, and wearing valve is less than 4.
The mineral aggregate gradation standard of bauxite mineral aggregate is as shown in table 1:
1 Friction Surface mineral aggregate gradation standard of table
| Screen size | Pass through % |
| 4.75mm | 100 |
| 3.35mm | 95~100 |
| 1.18mm | 0~5 |
| 0.6mm* | 0~1 |
The technical indicator of epoxy adhesive meets technical requirements listed by table 2:
2 epoxy resin bonding agent chemistry of table, physics and power performance indicator and requirement
Epobond epoxyn is the epoxy resin being composed of A, B component, nontoxic, non-volatile.
In specific work progress, laitance, greasy dirt, the graticule etc. on Friction Surface range Nei Lubiao are used into machinery side
Method is removed clean, and in-service cement pavement should be first using all discrete materials in shot-peening or blasting treatment road surface and its deblocking and miscellaneous
Then object is cleared up and is dried using vacuum cleaner, if bituminous pavement, should remove road table institute using steel wire rotary brush first
There are discrete material and sundries, is then cleared up and dried using vacuum cleaner.Epoxy adhesive two components of A and B are tight
Lattice are stirred according to control dosage, and ± 2% (calculating by volume) of specified volume is not to be exceeded in dosage error, and guarantees to stir
Sufficiently and uniformly.The epoxy resin being stirred should it is continuous, do not stop, equably spread to treated drying, clean road
Table.The dosage 1.20kg/m of epoxy resin2~1.85kg/m2, it is ensured that epoxy resin thickness is 1.3mm-1.7mm.
After epoxy resin spread is uniform, bauxite mineral aggregate should be dispensed immediately, when spreading, will avoid interference epoxy resin layer,
Bauxite mineral aggregate dosage is 7.32kg/m2~10.74kg/m2.Should be cleaned after antiskid layer is fully consolidated, with remove it is extra and
Loose mineral aggregate, and can open to traffic.The coefficient of friction (DFT) of Friction Surface is not less than 0.90 or texture depth is not less than
1.9mm。
Pavement structure Friction Surface of the invention can carry out single layer construction or carry out the double-deck construction.
Single layer form of construction work is as follows: handling original road surface by the way of shot-peening first, is carried out using vacuum cleaner clear
Reason and drying, two measured portions of epoxy adhesive A and B are mixed evenly, and spread paves in processed road table
It is even, bauxite mineral aggregate is dispensed immediately, and according to environment temperature, fencing lawn is carried out to Friction Surface, it is right after road surface is fully cured
Friction Surface is cleaned, can open to traffic after the extra and loose mineral aggregate of removing Friction Surface.The double-deck form of construction work is as follows:
Original road surface is handled by the way of shot-peening first, is cleared up and is dried using vacuum cleaner, by epoxy adhesive A
It being mixed evenly with two measured portions of B, spread paves uniformly in processed road table, dispenses bauxite mineral aggregate immediately, according to
Environment temperature carries out fencing lawn to Friction Surface, cleans after road surface is fully cured to Friction Surface, removes antiskid table
After the extra and loose mineral aggregate of layer, making second layer epoxy adhesive dispenses second layer bauxite mineral aggregate, to antiskid immediately
Surface layer carries out fencing lawn, and Friction Surface is cleaned after road surface is fully cured, and can open after removing extra and loose mineral aggregate
Traffic.
The foregoing is merely presently preferred embodiments of the present invention, not to carry out any restrictions, this field skill to the present invention
Art personnel are not it should be understood that in the range of departing from spirit of that invention principle, if form can also be carried out to technical solution
The modification or simple replacement of formula, these modifications and simple replacement also each fall within the protection scope determined by submitted claims
Within.
