Wear-resistant asphalt pavement

Technical Field

The utility model relates to the technical field of road engineering, in particular to a wear-resistant asphalt pavement.

Background

Asphalt pavement refers to various types of pavement that are made by incorporating into mineral materials a road asphalt material. The asphalt binder improves the capability of the paving aggregate to resist damage of traveling vehicles and natural factors to the pavement, and enables the pavement to be smooth, less in dust, impermeable and durable. Accordingly, asphalt pavement is one of the most widely used high-grade pavements in road construction. The asphalt structure layer of asphalt pavement belongs to the category of flexible pavement, but the base layer of the asphalt pavement can also adopt rigid cement concrete or semi-rigid hydraulic material besides flexible material.

In prior art, the vehicle is when the deceleration strip, because the vehicle still can keep certain speed for when the rear wheel of vehicle left the deceleration strip, can not laminate with the surface of deceleration strip, can directly fall on the road surface of deceleration strip one side behind the deceleration strip highest point, lead to certain impact to the road surface, the road surface that can lead to the deceleration strip both sides after long-time appears wearing and tearing and sinking.

Therefore, a new solution is needed to solve this problem.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide a wear-resistant asphalt pavement which can reduce the abrasion and sinking of the pavement on two sides of a deceleration strip.

The technical purpose of the utility model is realized by the following technical scheme: the utility model provides a wear-resisting bituminous paving, includes asphalt layer and fixed connection at its top surface and be curved deceleration strip, its characterized in that: fixedly connected with is located the articulamentum of deceleration strip both sides on the pitch layer, the articulamentum sets up and tangent with the periphery wall of deceleration strip with deceleration strip fixed connection and its top surface slope, the bottom surface fixedly connected with of articulamentum runs through the bradyseism subassembly on pitch layer.

Through adopting above-mentioned technical scheme, when utilizing the articulamentum that is located the deceleration strip both sides to make the vehicle pass through the deceleration strip, can not lead to the rear wheel of vehicle directly to fall on the pitch layer because the speed of a motor vehicle is too fast, thereby reduce the wearing and tearing to this road surface, the bradyseism effect when vehicle passes through the deceleration strip is strengthened to the bradyseism subassembly through articulamentum and articulamentum bottom surface, thereby realize letting the vehicle slow down but the effect that can steadily travel again, further avoid the injury on vehicle rear wheel pair road surface in the twinkling of an eye through the deceleration strip.

The utility model is further configured to: the connecting layer includes top layer and fixed connection at the buffer layer of its bottom surface, fixedly connected with a plurality of on the buffer layer just runs through the boss of top layer rather than integrated into one piece, the coefficient of friction of boss is greater than the coefficient of friction of top layer.

Through adopting above-mentioned technical scheme, when utilizing the boss to make the vehicle pass through the deceleration strip, the top surface contact of wheel and boss realizes letting the effect that the vehicle slowed down through frictional force, avoids leading to the condition emergence that the vehicle accelerated on the contrary not slowed down because the downhill path that the tie layer top surface formed.

The utility model is further configured to: the height of the boss is larger than or equal to the thickness of the top layer.

Through adopting above-mentioned technical scheme for the boss is easier with the wheel contact, and let the vehicle go and must flatten the boss when crossing the boss, strengthen the speed reduction effect of boss, and can also slow down the impact of vehicle to the top layer with buffer layer integrated into one piece's boss.

The utility model is further configured to: the bottom surface on pitch layer fixedly connected with concrete layer, metalling and base soil layer in proper order, the bradyseism subassembly includes that a plurality of follows the deceleration strip length direction array distribution hold frame and sliding connection at the support column that holds in the frame, it is located the concrete layer to hold the frame, support column and buffer layer fixed connection just run through the pitch layer, there is the effort that hinders support column gliding downwards between support column and the interior bottom surface that holds the frame.

Through adopting above-mentioned technical scheme, utilize the metalling to make this road surface have good hydrophobic effect, can avoid the road surface to produce ponding, make the rear wheel of vehicle go to the top layer from the deceleration strip through the support column with hold the frame, boss and buffer layer can produce deformation extrusion support column downwards, let the support column of holding in the frame come the impact force that further buffering came from the vehicle rear wheel.

The utility model is further configured to: the inner bottom surface of the accommodating frame is fixedly connected with a spring, and the other end of the spring is fixedly connected with the supporting column.

Through adopting above-mentioned technical scheme for the support column is difficult to the lapse in the one end that holds the frame, can receive the elasticity of spring all the time and by jack-up, strengthens the buffering effect on this road surface.

The utility model is further configured to: the asphalt layer and the top layer are both made of SBS modified asphalt.

By adopting the technical scheme, the elasticity, the toughness and the fatigue resistance of the pavement are improved by utilizing the SBS modified asphalt, so that the abrasion of the pavement is reduced.

In conclusion, the utility model has the following beneficial effects:

make the vehicle when the deceleration strip through the articulamentum that is located the deceleration strip both sides, can not lead to the rear wheel of vehicle directly to drop on the pitch layer because the speed of a motor vehicle is too fast to reduce the wearing and tearing to this road surface, the bradyseism effect when the vehicle passes through the deceleration strip is strengthened to the bradyseism subassembly through articulamentum and articulamentum bottom surface, thereby the realization lets the vehicle slow down but the effect that can steadily travel again, further avoid the injury on vehicle rear wheel pair road surface in the twinkling of an eye through the deceleration strip.
