Problems solved by technology

For example, rubber particle concrete and other rubber-infused materials are used in road engineering to build road surfaces, which improves the vibration reduction effect of the road surface to a certain extent. The impact of unfavorable factors such as tire wear seriously limits the life of its normal function; another example is the cement asphalt concrete pavement, that is, the pavement built with cement and emulsified asphalt as the binder. The effect is still not ideal

Embodiment 1

[0041] see figure 1 , image 3 , Figure 4 , the damping road structure of the present embodiment comprises asphalt mixture pavement layer 1, precast concrete road slab 2 and roadbed 5 from top to bottom, and a vibration isolation wall is arranged between the precast concrete road slab 2 and roadbed 5 CA mortar layer 3, a waterproof layer 4 is set between the CA mortar layer 3 and the roadbed 5; the CA mortar layer 3 and the waterproof layer 4 are naturally separated, the asphalt mixture pavement layer 1 and the precast concrete road slab The 2 are connected by the permeable layer oil and the sticky layer.

[0042] Wherein, the asphalt mixture pavement layer 1 includes an open graded anti-skid wear layer (OGFC) and a densely graded asphalt mixture (AC) as a road surface layer, and the preferred layer thickness and label are 30mm thick from top to bottom. OGFC- 10. 40mm thick AC-10.

[0043] Wherein, the prefabricated concrete road slab 2 has a thickness of 180mm, and an up...

Embodiment 2

[0055] The damping road structure of the present embodiment and the construction method thereof are basically the same as the first embodiment, and their difference is that in the present embodiment, the road surface layer of the asphalt pavement layer 1 preferably adopts asphalt horseshoe grease macadam ( SMA), the preferred layer thickness is 60mm, and the label is SMA-13.

Embodiment 3

[0057] see figure 2 , image 3 , Figure 4 , the damping road structure of the present embodiment comprises asphalt pavement layer 1, precast concrete road slab 2 and underground space roof 7 from top to bottom, and the precast concrete road slab 2 and underground space roof 7 are arranged between the Based on the vibration-isolated CA mortar layer 3, the asphalt mixture pavement layer 1 and the precast concrete road slab 2 are connected through a penetrating oil layer and an adhesive layer.

[0058] The construction method of the damping road structure, its paving sequence is as follows:

[0059] (1) Prefabricate concrete road slabs in the factory, and pre-embed steel bars 6 on the concrete road slabs;

[0060] (2) The upper surface of the underground space roof 7 is roughened or chiseled, and applied as a waterproof layer;

[0061] (3) paving the CA mortar layer 3 on the top surface of the rough underground space roof 7;

[0062] (4) Before the CA mortar layer 3 is ful...

Abstract

The invention provides a novel vibration reduction road structure and a construction method thereof. The vibration reduction road structure comprises a bituminous mixture pavement layer, prefabricated concrete road plates, a CA mortar layer, a waterproof layer and a roadbed or an underground space and other architectural structures from top to bottom. The construction method comprises the steps of roadbed constructing, waterproof layer laying, CA mortar layer paving, prefabricated concrete road plate assembling and connecting and bituminous mixture pavement layer paving from bottom to top in sequence. The vibration reduction road structure provided by the invention has the advantages that a 'dual vibration reduction' structural type (the first vibration reduction structural type body is the bituminous mixture pavement layer arranged on the surface, and the second vibration reduction structural type body is the CA mortar layer arranged under the road plates) is adopted, the better vibration reduction and isolation performance is displayed, and adjacent important buildings and other structures are protected from being disturbed by road vibration maximally; and in addition, the road structure further has good waterproofness and low-noise performance. By means of the advantages in all aspects, the road service life is remarkably prolonged advantageously.

Description

technical field [0001] The invention relates to the design field of pavement structures and construction methods thereof, in particular to a novel vibration-reducing road structure and construction methods thereof. Background technique [0002] Due to the unevenness of the road surface and the self-vibration of the vehicle engine, the vehicle will have an impact on the road surface when driving, thereby exciting the entire road surface structure to vibrate. The generation of secondary noise affects people's work and life. Especially in the road forms such as roads inside or above the underground space, elevated bridge pavement structures, road sections with high requirements for vibration and noise reduction, or roads near important buildings, a vibration-reducing and vibration-isolating structure is required. road structure. [0003] In the prior art, the following methods are generally used to reduce the vibration of the road surface: one is to set the vehicle's own vibr...
