Abstract
Description
Technical Field
[0001] This invention relates to the field of road and bridge engineering technology, and in particular to a method for constructing cast-in-place asphalt concrete steel bridge deck paving. Background Technology
[0002] Steel bridge deck paving is a key technical aspect of bridge engineering, and its quality directly affects the bridge's load-bearing capacity, driving comfort, and service life. Cast-in-place asphalt concrete has become a key solution for long-span steel bridge deck paving due to its excellent water tightness, ability to follow the deformation of the steel bridge deck, and construction characteristics that do not require compaction.
[0003] Traditional cast-in-place asphalt concrete steel bridge deck paving construction methods involve spraying an adhesive layer onto a pre-treated steel bridge deck, followed by spreading high-temperature mixed cast-in-place asphalt mixture on top. The mixture's self-leveling properties form a dense paving layer, which is then cooled and cured. The drawback of this method is the fixed paving layer thickness, which cannot adapt to the varying thickness requirements of different loads and bridge alignments. Current cast-in-place asphalt concrete steel bridge deck paving construction methods largely follow traditional processes, using pavers or manual labor, but lack integrated thickness adjustment functionality. This highlights the current lack of a convenient and reliable paving thickness adjustment device. The absence of such a device prevents flexible selection and real-time adjustments based on the bridge's actual alignment, local stiffness compensation, future maintenance and overlay requirements, and other needs. However, in practice, such devices are inconvenient to adjust, difficult to effectively coordinate with the paving process, and can damage the integrity of the paving layer and interlayer adhesion.

[0024] A method for constructing cast-in-place asphalt concrete steel bridge deck pavement, using the method described in any one of claims 1-9, includes the following steps:
[0025] S1. Pre-treatment of steel plate panels for steel bridges: Sandblasting process is used to thoroughly remove rust and clean the surface of the steel plates to obtain a clean, dry construction interface with a specified roughness.
[0026] S2. Pre-adjust the laying thickness on the pre-treated steel plate. By pressing the inner plate, adjust the inner plate and the three adjustment grooves. After the adjustment is completed, move the shifting wheel of the laying device to the rail plate and move it onto the steel plate until it is completely moved onto the steel plate.
[0027] S3. The first resin coating is evenly applied to the steel plate to form a buffer layer with both strong adhesion and flexibility. Then, the resin-modified asphalt concrete main load-bearing layer is poured on it. During the pouring process, a three-dimensional randomly distributed polymer fiber mesh is pre-embedded. Finally, before the main load-bearing layer is completely cured, a special equipment is used to embed the ceramsite crushed stone into its surface with a certain pressure to form an interlocking structure of the coating layer.
[0028] S4. When mixing the main load-bearing layer casting material, high-strength closed-cell hollow glass microspheres and temperature-induced phase change microcapsules are added according to the design ratio.

[0030] In summary, the present invention has at least one of the following beneficial technical effects:
[0031] 1. This invention provides multiple selectable fixing points for the vertical height position of the extension plate through multi-level adjustment grooves opened on the upright plate. Under the pre-tightening force and buffering effect provided by the spring, the sliding column can slide smoothly relative to the steel plate. After the height is adjusted to the correct position, the inner plate locks the extension plate in the selected adjustment groove. This mechanism realizes multi-level, stable and adjustable laying reference height, enabling construction to flexibly match different design thicknesses and alignment requirements.
[0032] 2. This invention lays a highly permeable resin coating on the top of a steel plate, which can tightly wet the steel plate and cure into a flexible adhesive buffer layer. Then, a polymer fiber mesh is laid on top of it, which enhances the tensile and shear strength of the overall structure and inhibits crack development. Next, ceramsite of a specific particle size is embedded into the incompletely cured lower layer under a certain pressure to form a mechanically interlocked rough surface layer. Finally, asphalt concrete is poured to form the main structural layer, which improves the overall bonding strength, fatigue resistance and deformation resistance of the pavement system.
[0033] 3. The present invention incorporates phase change microcapsules into the pavement layer, which can undergo reversible phase change when the ambient temperature changes, actively absorbing or releasing latent heat, thereby effectively buffering and dissipating the internal thermal stress generated by temperature cycling. When external loads or temperature stresses are applied to the pavement layer, the flexible microtubes disperse the concentrated stress and convert it into small deformation energy, thereby improving the pavement layer's ability to resist temperature cracking and load fatigue.

[0053] like Figure 7 and Figure 8 As shown, the construction method for cast-in-place asphalt concrete steel bridge deck pavement may include the following steps:
[0054] S1. Pre-treatment of the steel plate 1 panel of the steel bridge: Sandblasting process is used to thoroughly remove rust and clean the surface of the steel plate 1 to obtain a clean, dry construction interface with a specified roughness.
[0055] S2. The laying thickness is pre-adjusted on the pre-treated steel plate 1. By pressing the inner plate 306, the inner plate 306 and the three adjustment grooves 307 are adjusted. After the adjustment is completed, the laying device's transfer wheel 9 is aligned with the rail plate 305 and moved onto the steel plate 1 until it is completely moved onto the steel plate 1.
[0056] S3. A first resin coating 401 is uniformly coated on the steel plate 1 to form a buffer layer with both strong adhesion and flexibility. Then, a resin-modified asphalt concrete main load-bearing layer is poured on it. During the pouring process, a three-dimensional randomly distributed polymer fiber mesh 402 is pre-embedded. Finally, before the main load-bearing layer is completely cured, a special equipment is used to embed ceramsite 403 into its surface with a certain pressure to form an interlocking structure surface layer.
[0057] S4. When mixing the main load-bearing layer casting material, high-strength closed-cell hollow glass microspheres and temperature-induced phase change microcapsules 501 are added according to the design ratio. Flexible microtube grids 502 are laid on the buffer layer in the main stress direction. Then, a second resin film 503 is covered and poured to form a built-in stress and heat regulation microchannel structure.
[0058] S5. Pavement layer maintenance and post-treatment: After the paving construction is completed, maintenance shall be carried out in accordance with the specified conditions until the material reaches the design strength. When necessary, the built-in microchannel network can be used for diagnosis or injection of repair materials.
[0059] Working principle: The multi-level adjustment grooves 307 on the vertical plate 308 provide multiple selectable fixing points for the vertical height position of the extension plate 304. Under the pre-tightening force and buffering effect provided by the spring 303, the sliding column 302 can slide smoothly relative to the steel plate 1. After the height is adjusted to the correct position, the inner plate 306 locks the extension plate 304 in the selected adjustment groove 307. This mechanism realizes multi-level stable adjustment of the paving reference height, which allows the construction process to flexibly match different design thicknesses and alignment requirements, thereby ensuring accurate control of the paving layer thickness and surface flatness.
[0060] A highly permeable first resin film 401 is laid on top of the steel plate 1. This film can tightly wet the surface of the steel plate and cure into a flexible adhesive buffer layer. Then, a polymer fiber mesh 402 is laid on top of it. This mesh enhances the tensile and shear strength of the overall structure and effectively inhibits the initiation and development of cracks. Next, ceramsite 403 of a specific particle size is embedded into the incompletely cured lower layer under a certain pressure to form a mechanically interlocked rough surface layer. Finally, an asphalt layer 404 is poured to form the main structural layer. This composite structure improves the overall bonding strength, fatigue resistance and deformation resistance of the pavement system.
[0061] By incorporating phase change microcapsules 501 into the pavement layer, a reversible phase change occurs when the ambient temperature changes, actively absorbing or releasing latent heat, thereby effectively buffering and dissipating the internal thermal stress generated by temperature cycling. When external loads or temperature stresses are applied to the pavement layer, the flexible microtube mesh 502 can disperse the concentrated stress and convert it into tiny deformation energy. The second resin coating 503 covering it ensures the integrity of the internal structure. This mechanism improves the pavement layer's resistance to temperature cracking from the structural design level.
