Abstract
A color antiskid speed hump embedded in the road surface relates to a road surface structure of road engineering. Grooves are formed on the surface of roadway (1); a modified resin binding material layer (2) is poured into the groove; and a wearable color crushed rock layer (3) with crushed rocks with single diameter is applied on the modified resin binding material layer (2). The embedded color antiskid speed hump has the advantages of bright color, high alarm effect, high abrasion resistance and high antiskid capacity, and can reduce the speed without bumping when a vehicle passes the roadway.
Description
Technical field
The utility model relates to the highway construction road structure, the anti-skidding deceleration strip of embedded colour on especially a kind of pavement of road.
Background technology
Deceleration strip is as a kind of road safety means of transportation of enhanced type, and the important function of having brought into play to the containment traffic accident has obtained very big approval in recent years at home.Deceleration strip commonly used at present mainly contains railway spike deceleration strip, hump formula deceleration strip, cement platform deceleration strip, thermoplastic vibration deceleration strip, road surface Baltimore groove deceleration strip etc.Deceleration strip is as a kind of means of transportation that ensure that pedestrains safety is provided with, its basic principle is that certain projection facility is set on the runway of highway special road section, when automobile can produce violent mechanical oscillation with the higher speed of a motor vehicle by time on it, make the driver produce very uncomfortable feeling, in addition, the driver can bring the vehicle high vibration when expecting vehicle by deceleration strip according to general knowledge, and produces the doubt that may cause the vehicle parts to damage thus.The prediction of above-mentioned physiology and mental impression can reduce the traffic safety sensation (subjective sensation) of driver to this section highway, thus impel the vehicle driver conscious, reduce the speed of a motor vehicle on one's own initiative, reach the purpose that improves the special road section traffic safety.
The setting of deceleration strip makes the vehicle deceleration of running at high speed, and has effectively prevented the generation of traffic accident.But also, the part deceleration strip brought some inconvenience simultaneously to the user because of being provided with defective.
1) lacking " hommization " is provided with.Whenever people drive, ride will to be jolted through out-of-date heavyly, had a strong impact on comfortableness
2) noise pollution is serious.Vehicle can send the sound of " rub-a-dub rub-a-dub " by road hump, deceleration strip, and increases along with the increase of the speed of a motor vehicle, has formed noise pollution.
3) speed of a motor vehicle reduces excessive.Because the effect of jolting that deceleration strip forms is very big, thus vehicle during by deceleration strip often the speed of a motor vehicle reduce too much, by promptly speed-raising again behind the deceleration strip, vehicle fuel consumption obviously improves.
4) deceleration strip self antiskid DeGrain.The deceleration strip of present domestic employing is many based on strip speed-reducing rubber band and rigidity cement deceleration strip, these deceleration strips self antiskid DeGrain, the main anti-vehicle control speed of a motor vehicle of jolting.
Summary of the invention:
The purpose of this utility model be to design a kind of bright-colored, warning is strong, wear-resisting, anti-slide performance is strong, vehicle can either reach the effect that reduces the speed of a motor vehicle during by the road surface, does not produce the anti-skidding deceleration strip of embedded colour that jolts simultaneously again.
Technical scheme that the purpose of this utility model adopts is, form by driving road surface, the modified resin class bonding bed of material, wear-resisting colored macadam, have groove on its driving road surface, irritate the modified resin class bonding bed of material in the groove, at the wear-resisting colored macadam of modified resin class binding material laminar surface spreading single particle size.
The utility model, the surface of wear-resisting colored macadam flushes with the driving subgrade and pavement.
The utility model is slotted by road pavement, groove depth 5 ~ 7mm, and groove width and runway are wide, slotting length 5m.Pour into modified resin class binding material then,, reach the purpose of the reduction speed of a motor vehicle by the anti-slide performance of building stones self again at the color antiskid rubble of binding material surface spreading single particle size.
Pavement skid resistance condition is meant when vehicle tyre is subjected to braking along the power that surface sliding produced.Usually, cling property is counted as the surface characteristic on road surface, comprises thin structure of road surface and thick structure.The thin structure in road surface is meant the roughness of surface of aggregate, and it is polished gradually with the abrasion repeatedly of wheel, adopts the polishing value to characterize usually, and (30～50km/h is following) the table cling property that satisfies the need plays a decisive role when carefully being configured in low speed.And what play a decisive role during high speed is thick structure, is characterized by construction depth and friction factor usually.The antiskid effect of the anti-skidding deceleration strip of embedded colour adopts construction depth and friction factor to estimate on the pavement of road.
The test result of the anti-skidding deceleration strip friction factor of embedded colour on table 1 pavement of road
The test result of the anti-skidding deceleration strip surface texture depth of embedded colour on table 2 pavement of road
Table 1 and table 2 test result show, the friction factor of the anti-skidding deceleration strip of embedded colour is 71, be far longer than in the highway design specifications requirement (〉=45) to the high-grade highway friction factor, and construction depth is 2.54mm, also be far longer than in the highway in China design specifications requirement to the high-grade highway construction depth (〉=0.55mm).Therefore the anti-skidding deceleration strip of embedded colour has tangible antiskid effect, can play the reduction speed of a motor vehicle, guarantees the effect of traffic safety.
The utlity model has following advantage:
1) surface of wear-resisting colored macadam flushes with the driving subgrade and pavement, does not have the protrusion place, thereby has effectively avoided the jolting of vehicle increased the enforcement comfortableness of vehicle;
2), so self has superior cling property owing to the anti-skidding deceleration strip of embedded colour surface is made of the very big diamond dust of hardness that one deck gathers;
3) bright in luster, abundant, lasting, can play good warning function;
4) vehicle by the time needn't bring to a halt, the reduction speed of a motor vehicle of the cling property nature by material self can be saved fuel consumption greatly.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model example structure sectional schematic diagram.
Among the figure: the wear-resisting colored macadam of 1-driving road surface 2-modified resin class bonding bed of material 3-
Five, the specific embodiment
As shown in drawings, form by driving road surface 1, the modified resin class bonding bed of material 2, wear-resisting colored macadam 3, have groove on its driving road surface 1, pour into the modified resin class bonding bed of material 2 in the groove, at the wear-resisting colored macadam 3 of the modified resin class bonding bed of material 2 surperficial spreading single particle sizes.The surface of wear-resisting colored macadam 3 flushes with driving road surface 1.
