Abstract
Description
Technical Field
[0001] This utility model specifically relates to a construction slab for an asphalt plaza road surface at a test site. Background Technology
[0002] A test track typically refers to a specific site dedicated to conducting specialized tests, research, and evaluations. It is usually an independently designated area, but may also be a test section within a large road construction project. Early road surface materials, such as cement concrete, while possessing high strength, were also quite rigid. In a test track environment, the vibrations and impacts generated by vehicles could significantly affect the road surface and vehicles. Therefore, nowadays, asphalt paving is widely used for large-area test track pavements. After asphalt paving, it exhibits excellent skid resistance and flexibility, better adapting to changes in the road base layer, absorbing the impact forces generated by vehicles, reducing damage to the road structure, and extending its service life.
[0003] Currently, for the paving of large-area asphalt concrete pavements, the overall slabs are usually divided into hot-jointed slab paving and cold-jointed slab paving. However, if manual paving is used in the process of paving large-area asphalt pavements, there will be difficulties in compaction, and the joints of cold-jointed slabs are more difficult to connect, resulting in low qualification rates for elevation and flatness, which seriously affects the quality of the pavement after paving.
[0004] Therefore, it is necessary to invent a construction slab for asphalt plaza pavement in a test field to solve the above problems. Utility Model Content
[0005] (a) Purpose of the utility model
[0006] To address the technical problems existing in the background art, this utility model proposes a construction slab for asphalt plaza pavement in a test field, which solves the problems of difficulty in manual paving and compaction and difficulty in connecting cold joints.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a test field asphalt plaza pavement construction slab, comprising multiple paving slab groups and an outer arc ring slab set on the asphalt plaza pavement;
[0009] The multiple paving slab groups are divided into two slabs on both sides with the center line of the asphalt plaza pavement as the central axis, and the paving slab groups on both sides are symmetrically arranged.
[0010] Each of the paving slab groups includes two hot-jointed slabs and one cold-jointed slab, with the cold-jointed slab positioned between the two hot-jointed slabs;
[0011] The outer arc ring plate is placed at the edge of the asphalt plaza pavement.
[0012] Preferably, the hot-jointed slab and the cold-jointed slab are of the same width, both being 6m, and corresponding to the shape of the asphalt plaza pavement, the length of each hot-jointed slab and the cold-jointed slab gradually changes, with the longest being 700m and the shortest being 123m.
[0013] Preferably, the centerline of the asphalt plaza pavement is divided into heat-sealed joints.
[0014] Preferably, the asphalt plaza pavement also has functional zones on both sides of its center line, and the paving of both the hot-jointed slabs and the cold-jointed slabs does not exceed the functional zones.
[0015] Preferably, the outer arc ring plate wraps around the outside of the asphalt plaza pavement, that is, wraps around both ends of the hot-joint plate and the cold-joint plate.
[0016] Preferably, both the outer arc ring plate and the functional area are laid mechanically.
[0017] Compared with the prior art, the beneficial effects of the above-mentioned technical solution of this utility model are:
[0018] 1. This utility model solves the problem of poor quality in manually paved areas by rationally dividing the paving slabs into sections and using extra-wide paving for curved sections and irregular areas. Each slab is formed in one paving operation.
[0019] 2. This utility model effectively reduces the difficulty of connecting cold joints by using alternating hot and cold slabs, and improves the pass rate of elevation and flatness. Attached Figure Description
[0020] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this utility model. For those skilled in the art, other drawings can be obtained based on these drawings.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figure 1-2 The diagram shows a test field asphalt plaza pavement construction slab, which includes multiple paving slab groups 2 and an outer arc ring slab 3 set on the asphalt plaza pavement 1;
[0027] Specifically, multiple paving slab groups 2 are divided into two slabs on both sides with the center line of the asphalt plaza pavement 1 as the central axis, and the paving slab groups 2 on both sides are symmetrically arranged;
[0028] Specifically, each paving slab group 2 includes two hot-jointed slabs 4 and one cold-jointed slab 5, with the cold-jointed slab 5 placed between the two hot-jointed slabs 4;
[0029] Specifically, the outer arc ring plate 3 is placed at the edge of the asphalt plaza pavement 1.
[0030] In this embodiment, the paving slabs are divided into three types: hot-jointed slabs 4, cold-jointed slabs 5, and outer arc ring slabs 3. The paving width of each slab is 6m, and the length of each slab gradually changes, with the longest being 700m and the shortest being 123m.
[0031] In this embodiment, the road centerline is used as the central axis for paving, with equal widths on both sides. The road centerline is divided into hot-joint slab joints, and the slab width is symmetrically divided from the centerline to both sides. Taking the width of the first slab as a reference, the paving slab width is then cyclically divided to both sides in the form of "hot-joint slab + cold-joint slab + hot-joint slab". This symmetrical layout helps to ensure the balance and aesthetics of the pavement structure, and also facilitates operation and management during construction.
[0032] In this embodiment, the arc-shaped area is mainly the edge of the circular test area. Due to the limitations of the fill and cut slope, there are areas of varying sizes at the ends of each slab that require manual work during paving. Therefore, the arc-shaped area adopts an over-lay milling and then ring-shaped paving method.
[0033] Reference Figure 2 Hot-jointed slab 4 and cold-jointed slab 5 are of equal width, both 6m, and correspond to the shape of asphalt plaza pavement 1. The length of each hot-jointed slab 4 and cold-jointed slab 5 gradually changes, with the longest being 700m and the shortest being 123m. The uniform width design facilitates the operation of construction equipment and the uniform spreading of materials.
[0034] Specifically, the center line of the asphalt plaza pavement 1 is divided into hot-joint joints.
[0035] In this embodiment, the centerline of the asphalt plaza pavement 1 is divided into heat-bonded joints. This design requires special treatment of the heat-bonded joints during construction, such as using appropriate heat-bonding techniques to ensure a tight connection between the slabs and prevent problems such as cracks.
[0036] Specifically, the asphalt plaza pavement 1 also has functional zones 6 on both sides of its center line, and the paving of hot-joint slabs 4 and cold-joint slabs 5 does not exceed the functional zones 6.
[0037] In this embodiment, functional zones 6 are provided on both sides of the centerline of the asphalt plaza pavement 1. The paving range of both hot-jointed slabs 4 and cold-jointed slabs 5 must not exceed the functional zone 6. Before construction, the boundaries of the functional zone 6 need to be clearly defined, and the paving range of the slabs must be strictly controlled during the paving process to ensure the integrity of the functional zone 6 and the normal functioning of the functional zone 6.
[0038] Specifically, the outer arc ring plate 3 wraps around the outside of the asphalt plaza pavement 1, that is, it wraps around both ends of the hot-joint plate 4 and the cold-joint plate 5.
[0039] In this embodiment, the outer arc ring plate 3 is positioned at the edge of the asphalt plaza pavement 1, wrapping around both ends of the hot-jointed plate 4 and the cold-jointed plate 5. During construction, the outer arc ring plate 3 needs to be tightly connected to the edges of the hot-jointed plate 4 and the cold-jointed plate 5 to ensure the integrity of the entire pavement.
[0040] Specifically, both the outer arc ring plate 3 and the functional area 6 are mechanically paved.
[0041] In this embodiment, both the outer arc-shaped ring plate 3 and the functional area 6 are paved mechanically. This requires selecting appropriate paving machinery during construction and precisely adjusting the machinery's operating parameters to ensure the smoothness and compaction of the paved surface. For example, the paving speed, vibration frequency, and other parameters of the paver are adjusted according to different plate widths and lengths.
[0042] In this embodiment, a stable road surface structure is formed by the combination of hot-jointed plate 4, cold-jointed plate 5, and outer arc ring plate 3. The reasonable layout between the hot-jointed plates 4 and between the hot-jointed plates 4 and the cold-jointed plates 5 allows the road surface to distribute stress evenly when subjected to external forces such as vehicle loads.
[0043] In this embodiment, although the heat-bonded joint at the road centerline is the connection point between the slabs, the connection strength between the slabs can be enhanced through appropriate heat-bonding technology. During the heat-bonding process, the asphalt material fuses at high temperature, forming a relatively continuous structure, further improving the overall stability of the road surface.
[0044] In this embodiment, multiple paving slab groups 2 are symmetrically arranged around the road centerline, which facilitates operation and management by construction personnel during construction. The outer arc ring slab 3 and functional area 6 are paved mechanically, ensuring the flatness and compactness of the paving. Compared with manual paving, mechanical paving is more uniform and precise, and can effectively control the paving thickness and material distribution.
[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
