Problems solved by technology

[0004] The above-mentioned prior art solution has the following defects: the warm-mixed asphalt mastic macadam layer and the high-modulus asphalt mixture layer are only bonded together through the adhesive layer, and are located at the top during the sudden braking of the vehicle. The warm-mix asphalt mastic macadam layer is subjected to a huge force from the vehicle. When the adhesive force of the adhesive layer cannot counteract this force, it is easy to cause the warm-mix asphalt mastic macadam layer and high modulus Slippage occurs between layers of asphalt mixture, forming bumps or pits on the road surface

Embodiment 1

[0043] like figure 1 As shown, a high-strength pavement includes a soil layer 1, a graded crushed stone layer 2, a concrete layer 3 and an asphalt layer 4 from bottom to top.

[0044] like figure 2 As shown, the concrete layer 3 is laid with steel mesh 5 along the horizontal direction, and the crack resistance of the concrete layer 3 is improved through the steel mesh 5 . Each node of the reinforcement mesh 5 is bound with a vertically oriented vertical steel bar 6, the lower end of the vertical steel bar 6 is inserted into the graded crushed stone layer 2, and the upper end of the vertical steel bar 6 passes through the concrete layer 3, and each There is a distance of 10 cm between the uppermost ends of the vertical steel bars 6 and the upper end surface of the concrete layer 3 .

[0045] like figure 2 and image 3 As shown, the vertical reinforcing bars 6 arranged on the same straight line along the width direction of the road are divided into two by taking the center...

Embodiment 2

[0048] A construction method for the above-mentioned high-strength pavement, comprising:

[0049] Step 1. Laying graded gravel layer 2

[0050] Pour and level the fine crushed stones above the soil layer 1, then lay and level the crushed stones with slightly larger particles, and repeat the above steps to lay the graded crushed stone layer 2.

[0051] Step 2. Build the steel frame

[0052] Build a horizontal reinforcement mesh 5 above the graded crushed stone layer 2, and bind vertically oriented vertical reinforcement bars 6 on each node of the reinforcement mesh 5, the lower end of the vertical reinforcement bars 6 is inserted into the graded crushed stone layer 2 Inside, and ensure that the upper ends of the vertical steel bars 6 are flush. The vertical steel bars 6 arranged on the same straight line along the width direction of the road are divided into two with the centerline of the road as the dividing line as two steel bar groups. The position of the side is pre-ground...

Abstract

The invention relates to the technical field of road construction, in particular to a high-strength road surface and a construction process thereof. The high-strength road surface has the advantage ofbeing not prone to forming bulges or concave pits. The high-strength road surface sequentially comprises a soil layer, a graded rubble layer, a concrete layer and an asphalt layer from bottom to top.Upright steel plates are arranged in the concrete layer, the steel plates are arranged in the width direction of a road and the lower ends of the steel plates are located in the concrete layer, and the upper ends of the steel plates exceed the upper surface of the concrete layer and extend into the asphalt layer. The steel plates can play a reinforcing effect to a certain degree when travelling vehicles brake urgently to reduce the possibility of the bulges or the concave pits appearing on the road surface due to the fact that the steel plates are arranged in the width direction of the road,and the upper and lower ends of the steel plates are correspondingly located in the concrete layer and the asphalt layer.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a high-strength road surface and its construction technology. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. [0003] The utility model patent with the authorized announcement number CN203270399U discloses an asphalt pavement. The asphalt pavement consists of warm mixed asphalt mastic macadam layer, high modulus asphalt mixture layer, emulsified asphalt factory mixed cold regeneration layer, Rubber asphalt stress absorbing course and base course. [0004] The above-mentioned prior art solution has the following...
