Abstract
A kind of basalt fibre road surface, for multilayer laminate constructions road surface, bottom-uply be followed successively by roadbed, macadam, asphalt concrete pavement layer, composite asphalt layer and bitumastic layer, described composite asphalt layer is Double-layer asphalt structure, the side of its laminating asphalt concrete pavement layer is rubber modified asphalt layer, and on rubber modified asphalt layer, also form the epoxy resin modified asphalt layer that one deck is added with basalt fibre, and be covered with the basalt fiber cloth that a layer thickness is 2 ~ 3mm between the epoxy resin modified asphalt layer and rubber modified asphalt layer of composite asphalt layer.The utility model Stability Analysis of Structures, weatherability are good, simultaneously good with roadbed associativity and resist the superior performance of external force.
Description
Technical field
The utility model relates to the treatment of road surfaces technology in urban construction field, is specially a kind of basalt fibre road surface of better weatherability.
Background technology
In highway construction field, flexible pavement is few with its good mechanical property, smooth wear-resisting surface, steadily comfortable train operation performance, airborne dust, it is little to vibrate, noise is low, the construction period is short and the feature such as simple maintenance is subject to the favor of numerous country of the world.But, because flexible pavement pitch class formation layer itself belongs to flexible pavement category, its basic unit is except flexible material, also the cement concrete of rigidity can be adopted, or semirigid hydraulic material carries out place mat, there is obvious drying shrinkage and temperature contracting, outside the traffic loading bearing design, also subject the impact of climate change (high temperature, low temperature, sleet etc.), be very easy to produce crack therein.
And in each influence factor of road pavement, hot environment and heavy load the most obvious on the impact of flexible pavement, because bituminous mixture is typical simple hot rheo-material, its mechanical characteristic has the sensitiveness of height to temperature and loading mode and magnitude of load, in high temperature, volume of traffic is large, heavy load vehicle is many section, flexible pavement is in complex stress state of strain, is very easy to produce permanent deformation and Plastic Flow and cause road surface structare layer generation deformation of unevenness.
Utility model content
The technical problem that the utility model solves is to provide a kind of basalt fibre road surface, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of basalt fibre road surface, for multilayer laminate constructions road surface, bottom-uply be followed successively by roadbed, macadam, asphalt concrete pavement layer, composite asphalt layer and bitumastic layer, wherein, described composite asphalt layer is Double-layer asphalt structure, the side of its laminating asphalt concrete pavement layer is rubber modified asphalt layer, and on rubber modified asphalt layer, also form the epoxy resin modified asphalt layer that one deck is added with basalt fibre, and the basalt fiber cloth that a layer thickness is 2 ~ 3mm is covered with between the epoxy resin modified asphalt layer and rubber modified asphalt layer of composite asphalt layer.
In the utility model, in described rubber modified asphalt layer, basalt fibre content is 20 ~ 30% of rubber modified asphalt material gross mass percentage.
In the utility model, the aggregate in described macadam is limestone or granite or basalt.
In the utility model, basalt fibre road surface is high in the middle of being preferably, road structure that both sides are low, and line between road surface minimum point and road surface peak and the angle between horizontal plane are 3 ~ 5 °.
Beneficial effect: road structure of the present utility model has stronger weatherability, good toughness, and anti-fatigue performance is good, can efficient hardening road surface supporting capacity; Meanwhile, stable performance, long service life, can effectively reduce maintenance of surface expense.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Wherein: 1, bitumastic layer; 2, epoxy resin modified asphalt layer; 3, basalt fiber cloth; 4, rubber modified asphalt layer; 5, asphalt concrete pavement layer; 6, macadam; 7, roadbed.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See the preferred embodiment on a kind of basalt fibre road surface of Fig. 1, in the present embodiment, basalt fibre road surface is the road structure that centre is high, both sides are low, line between its road surface minimum point and road surface peak and the angle between horizontal plane are 5 °, and road surface comprises roadbed 7, macadam 6, asphalt concrete pavement layer 5, rubber modified asphalt layer 4, basalt fiber cloth 3, epoxy resin modified asphalt layer 2 and bitumastic layer 1 from bottom to top respectively.Wherein, the aggregate of macadam 6 is granite, and it to be positioned on roadbed 7 as main forced section as load-bearing basic unit, is provided with one deck asphalt concrete pavement layer 5 as cushion coat and auxiliary bearing course, simultaneously for filling the gap between macadam 6; And bitumastic layer 1 is compression face, be mainly used in the direct pressure of bearing wheel, dividing potential drop is carried out by epoxy resin modified asphalt layer 2 and rubber modified asphalt layer 4 in its underpart, effectively can reduce surface deformation.
Simultaneously, epoxy resin modified asphalt layer 2 is evenly mixed with the basalt fibre accounting for epoxy resin modified asphalt material total mass ratio 20% in the present embodiment, and to be also provided with a layer thickness between epoxy resin modified asphalt layer 2 and rubber modified asphalt layer 4 be 2mm basalt fiber cloth 3, toughness and the weatherability on road surface effectively can be improved by epoxy resin modified asphalt layer 2 and the acting in conjunction of basalt fiber cloth 3.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
