Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a crack-resistant asphalt pavement. Background Technology

[0002] Asphalt pavement is a common road surface material, composed of asphalt mixture, aggregate, and filler. The asphalt mixture is the main binder, responsible for binding the aggregate particles together. The aggregate includes coarse and fine aggregates, the size and shape of which greatly affect the pavement's performance. Filler is used to fill the gaps between the aggregate particles, improving the pavement's density and stability. Asphalt pavement is further divided into asphalt concrete pavement, which uses a mixture of asphalt mixture and aggregate; asphalt macadam pavement, composed of asphalt binder and larger-diameter crushed stone, used for secondary and temporary roads; and asphalt mastic macadam pavement, which has excellent durability and anti-skid properties. Asphalt pavement is a high-performance, widely used road surface material, playing a vital role in improving transportation efficiency and ensuring driving safety.

[0003] A search revealed Chinese Patent Publication No. CN217810293U, which discloses a crack-resistant asphalt pavement structure. This structure includes an asphalt surface layer, a film seal layer, a transition layer, and a semi-rigid base layer. The asphalt surface layer is located above the film seal layer, the transition layer is below the film seal layer, and the semi-rigid base layer is below the transition layer. The semi-rigid base layer is made of lime, fly ash, and cement, and the film seal layer is made of rubber asphalt. This crack-resistant asphalt pavement structure, by incorporating a transition layer composed of graded crushed stone, significantly mitigates reflective cracking. The stress-absorbing film seal layer absorbs apical stress and delays cracking. The rubber asphalt material effectively reduces reflective cracking. Glass grids, a novel reinforcing material made from high-temperature strength glass fiber, possess high tensile strength and elastic modulus, low elongation, and a high melting point, providing excellent resistance to deformation, alleviating fatigue cracking, and preventing reflective cracking. However, it cannot drain liquids that seep into the pavement due to aging after prolonged use, leading to softening and damage to the subgrade, reduced service life, and decreased practicality.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see the appendix Figure 1 - Appendix Figure 3 The present invention provides an embodiment of a crack-resistant asphalt pavement, comprising a pavement 1, the inner wall of which is provided with a plurality of water seepage holes 4, the pavement 1 being used to carry pedestrians, a permeable membrane 5 being fixedly connected to the bottom of the pavement 1, a roadbed 3 being fixedly connected to the bottom of the permeable membrane 5, the permeable membrane 5 being used to prevent groundwater from seeping upwards, a plurality of water collection troughs 6 being provided on the inner wall of the roadbed 3, a first inclined block 8 being fixedly connected to the inner wall of the water collection trough 6, and a drainage hole 7 being provided in the middle of the inner wall of the water collection trough 6, the water collection trough 6 being used to collect liquid and then discharge it.

[0040] Specifically, the water collection trough 6 can prevent water from accumulating inside the roadbed 3, thereby avoiding roadbed softening and damage 3. The drainage hole 7 allows water in the water collection trough 6 to be discharged smoothly, further ensuring the dryness and stability of the road surface 1. The permeable membrane 5 has good one-way permeability and can prevent damage to the road surface 1 caused by groundwater seepage. The seepage hole 4 is designed to collect and discharge the liquid seeping down the road surface 1. The first inclined block 8 can collect the liquid in the water collection trough 6 and guide it into the drainage hole 7 so that it can be discharged smoothly.

[0041] Please see the appendix Figure 2 - Appendix Figure 4 A water channel 10 is fixedly connected to the bottom of the roadbed 3. A second inclined block 11 is fixedly connected to the inner wall of the water channel 10. The water channel 10 is used to guide the liquid out. A crack-resistant structure 2 is fixedly connected to the inner wall of the road surface 1. The crack-resistant structure 2 is used to prevent the ground from cracking. Filter plates 9 are fixedly connected to both the left and right sides of the water channel 10. The filter plates 9 are semi-circular in shape. The filter plates 9 are used to prevent external debris from entering the water channel 10.

[0042] Specifically, the water channel 10 is used to collect dripping rainwater. The second inclined block 11 can guide the liquid in the water channel 10 to flow to both sides, thereby discharging it from the water channel 10. The filter plate 9 can prevent external debris from entering the water channel 10, ensuring the normal drainage of the water channel 10. At the same time, the semi-circular filter plate 9 can discharge the liquid more quickly when there is a lot of liquid. The crack-resistant structure 2 can prevent the road surface 1 from cracking after long-term use, which would increase the accident rate of vehicles passing on it.

[0043] Please see the appendix Figure 3 - Appendix Figure 5 The crack-resistant structure 2 includes a steel mesh 203. The outer wall of the steel mesh 203 is fixedly connected to the inner wall of the road surface 1. A cement layer 202 is fixedly connected to the top of the steel mesh 203. The steel mesh 203 is used to improve the tensile strength of the road surface 1. An expansion joint 205 is provided at the bottom of the steel mesh 203. An asphalt layer 201 is fixedly connected to the top of the cement layer 202. A sand and gravel layer 204 is fixedly connected to the inner wall of the expansion joint 205. The expansion joint 205 is used to prevent the road surface 1 from cracking due to thermal expansion and contraction. A base layer 206 is fixedly connected to the bottom of the sand and gravel layer 204. Multiple steel meshes 203 are fixedly connected at the same horizontal height. A ground wire 13 is fixedly connected to the outer wall of the steel mesh 203. The ground wire 13 is used to prevent the steel mesh 203 from being oxidized and corroded due to static electricity.

[0044] Specifically, the sand and gravel layer 204 not only serves as a filling material but also absorbs and disperses stress, further enhancing the crack resistance of the structure. The foundation layer 206, as the bottom layer of the entire crack-resistant structure 2, plays an important role in transferring the load to the foundation. The ground wire 13 can prevent the steel mesh 203 from being oxidized by the electrodes through grounding. The expansion joint 205 can adapt to the expansion and contraction of materials caused by temperature changes, thereby effectively preventing the generation of cracks. The asphalt layer 201, as the surface layer of the road surface 1, provides good driving comfort and durability. The cement layer 202 not only enhances the load-bearing capacity of the structure but also provides a solid foundation for the road surface 1.

[0045] Please see the appendix Figure 1 - Appendix Figure 2 Multiple water collection troughs 6 are all opened at the same horizontal height. The first inclined block 8 and the second inclined block 11 are both designed with inclined surfaces. A zebra crossing 12 is fixedly connected to the top of the road surface 1. The water collection troughs 6 at the same horizontal height ensure the consistency of drainage. Multiple zebra crossings 12 are fixedly connected at the same horizontal height. The inner wall of the seepage hole 4 is connected to the inner wall of the water collection trough 6. The zebra crossing 12 can guide pedestrians to pass. The water diversion trough 10 is designed as a semi-cylindrical structure. Multiple drainage holes 7 are all opened at the same horizontal height. The inner wall of the drainage hole 7 is connected to the inner wall of the water diversion trough 10. The semi-cylindrical design of the water diversion trough 10 allows the liquid inside to flow faster.

[0046] Specifically, the semi-cylindrical design of the water channel 10 is not only aesthetically pleasing but also effectively guides water flow. The drainage holes 7 at the same level ensure uniformity of drainage. The zebra crossings 12 not only provide a safe passage area for pedestrians but also enhance the aesthetics of the road surface 1. The inner wall of the seepage hole 4 is connected to the inner wall of the water collection trough 6, ensuring that the infiltrated rainwater can quickly collect from the road surface 1 into the water collection trough 6. The water collection trough 6 at the same level ensures that the infiltrated rainwater can be collected at the same time. The inclined structure of the first inclined block 8 and the second inclined block 11 allows the liquid falling on them to be guided to flow along their inclined surfaces.

[0047] Working principle: When water seeps downward from the top of the road surface 1 due to the material, the liquid will flow downward along the seepage hole 4, pass through the seepage membrane 5 and flow into the water collection tank 6. It is fixed by multiple first inclined blocks 8 facing each other, so as to ensure that the liquid is collected in the water collection tank 6 and flows into the water diversion tank 10 along the drainage hole 7. Then it flows along the second inclined block 11 to the drainage ditches on both sides of the road, and the filter plate 9 prevents the liquid in the drainage ditch from carrying debris back into the water diversion tank 10.

[0048] The foundation layer 206 is used to fix the foundation of the entire structure, and the sand and gravel layer 204 is used to buffer the pressure on the top and reduce the possibility of cracking. At the same time, the expansion joint 205 can prevent the road surface 1 from cracking due to compression caused by thermal expansion and contraction. Meanwhile, the steel mesh 203, together with the cement layer 202, can further reinforce the top asphalt layer 201.

[0049] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
