[0002] The information disclosed in this background technology section is only intended to increase some understanding of the overall background of the invention, and should not be necessarily regarded as an admission or any form of suggestion that the information constitutes the prior art already known to ordinary technicians in this field.

[0003] With the rapid development of human society and economy, while improving people's production and living conditions, ecological environment pollution has become increasingly prominent, hindering the sustainable development of human society. As an important part of "green development", the "green" transformation of road construction materials is imperative. In order to achieve the goal of carbon dioxide emissions, the country has clarified the comprehensive utilization plan of bulk solid waste and proposed comprehensive utilization rate, technical system, legal system and industrial structure.

[0004] At present, reinforced concrete road slabs are mostly used in road construction, which have poor toughness and the production of steel bars requires a lot of energy. Especially in the process of smelting iron ore and producing steel, it will lead to greenhouse gas emissions and high dependence on energy resources. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a green and low-carbon road construction technology system, including an improved soil roadbed based on basalt solid waste and a basalt fiber reinforced pavement. Through this technology system, the effective utilization of basalt solid waste can be achieved, the carbon emissions in the road construction process can be reduced, and the toughness of the pavement can be enhanced. It can consume garbage and obtain building materials, and has the advantages of emission reduction and environmental protection.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solutions: The present invention provides a green and low-carbon road construction method based on basalt products, the method comprising the following steps: (1) Preliminary preparation work, including roadbed excavation and material preparation, in order to carry out subsequent work; (2) Paving with bare soil, and spreading water, cement, basalt solid waste and alkali activated materials; (3) Road base mixing and maintenance; (4) Laying slurry in layers; (5) Paving material laying, cement concrete pavement reinforced with basalt fiber bars; (6) Installation of intelligent road temperature control system; (7) Pavement layer maintenance.

[0007] In one or some embodiments of the present invention, in step (1), the material includes basalt solid waste improved soil and alkali-activated material. The optimal ratio of basalt solid waste improved soil and alkali-activated material was obtained through laboratory test verification. The alkali-activated material is a composite of one or more of lime, sodium carbonate, sodium hydroxide, and sodium silicate, and the basalt solid waste improved soil is composed of cement, basalt solid waste, plain soil and water. Among them, the proportion of cement to basalt solid waste is 10w / w%-15w / w%, and the mass ratio of basalt solid waste: plain soil: water: alkali activator is (18-20): (160-170): (25-27): 1.

[0008] In one or some embodiments of the present invention, in step (2), the raw soil is spread, and the volume of the raw soil is controlled by a grid, and the raw soil is air-dried. Specifically, it includes: using a 100 cm×100 cm grid to control the volume of the raw soil, and the moisture content of the raw soil during air-drying is controlled to be below 2w / w%, so as to subsequently calculate the amount of cement, basalt solid waste, and watering.

[0009] In one or some embodiments of the present invention, in step (2), when spreading the material, a numerically controlled high-precision flow control valve is used to control the spreading amount.

After mixing, the improved soil is required to have a uniform color without gray lumps or flowery surfaces.

[0011] After the basalt solid waste improved soil is mixed, it is leveled and compacted. Specifically, it includes: first using a grader for initial leveling, then using a roller for compaction. The number of rolling times is determined by the specific project and site conditions until the compaction reaches the specified standard; further, when rolling with a roller, the straight section is required to be rolled from the middle to both sides, and the curved section is rolled from the low side to the high side to ensure the uniform density of the road surface. Roadbed surface maintenance, maintenance is carried out after rolling and testing are completed, and vehicles are prohibited from passing during the maintenance period.

[0012] In one or some embodiments of the present invention, in step (4), the slurry layering adopts emulsified asphalt slurry layering, which can effectively prevent the slight corrosion effect of the improved soil roadbed on the road surface.

[0013] In one or some embodiments of the present invention, step (5) includes: tying and installing basalt fiber reinforcement mesh; pouring concrete and vibrating it evenly; smoothing and finishing the concrete, and fine-leveling the surface after vibrating it densely. After the concrete begins to solidify, a smoothing machine is used to smooth the entire surface.

[0014] Furthermore, the fiber reinforcement net is a double-layer basalt fiber reinforcement net, and both layers of fiber reinforcements include transverse fiber reinforcements and longitudinal fiber reinforcements, and both use basalt threaded fiber reinforcements with a diameter of 1 to 1.2 cm.

[0015] Furthermore, in the fiber reinforcement net, the longitudinal fiber reinforcement is 9 to 10 cm away from the surface of the surface layer, the spacing is 20 to 22 cm, and the overlap length is 10 to 12 times the diameter of the fiber reinforcement.

[0016] Furthermore, in the fiber reinforcement net, the transverse fiber reinforcements should be located below the longitudinal fiber reinforcements with a spacing of 50-55 cm, and the transverse fiber reinforcements are arranged obliquely with an angle of 59-61° with the longitudinal fiber reinforcements.

[0017] Furthermore, the corners of the concrete slab should be vibrated first with an inserted vibrator and then evenly vibrated with a flat vibrator. Care should be taken when vibrating the basalt fiber reinforcement to prevent the fiber reinforcement from being displaced.

[0018] In one or some embodiments of the present invention, in step (6), the road surface intelligent temperature control system is composed of a high-precision infrared temperature monitor, an alarm device and an automatic sprinkler.

[0019] In one or some embodiments of the present invention, in step (7), the pavement intelligent temperature control system is combined to accelerate the maintenance of the pavement layer. When the temperature is too high, the system issues an alarm and the automatic sprinkler starts to spray water to cool down.

[0020] In one or some embodiments of the present invention, the road base layer has a thickness of 35-40 cm, the slurry layer has a thickness of 0.3-0.5 cm, and the pavement layer has a thickness of 28-30 cm.

[0051] Step nine: Install and tie the fiber reinforcement mesh. The fiber reinforcement mesh is a double-layer basalt fiber reinforcement mesh. Both layers of fiber reinforcement include transverse fiber reinforcement 3 and longitudinal fiber reinforcement 2. Both use basalt threaded fiber reinforcement with a diameter of 1 cm. The longitudinal fiber reinforcement 2 is 10 cm away from the surface of the surface layer, with a spacing of 20 cm, and the overlap length is 10 times the fiber reinforcement diameter.

[0062] Step 7: Maintenance of road base 2, after rolling and testing, maintenance is carried out. Vehicles are prohibited from passing during the maintenance period. Figure 1 .

[0063] Step 8: Lay emulsified asphalt slurry in layers 4.

[0064] Step nine: Install and tie the fiber reinforcement mesh. The fiber reinforcement mesh is a double-layer basalt fiber reinforcement mesh. Both layers of fiber reinforcements include transverse fiber reinforcements 3 and longitudinal fiber reinforcements 2. Both use basalt threaded fiber reinforcements with a diameter of 1.2 cm. The longitudinal fiber reinforcements 2 are 9.8 cm away from the surface of the surface layer, with a spacing of 21.5 cm, and the overlap length is 10.5 times the fiber reinforcement diameter. The transverse fiber reinforcements 3 should be located below the longitudinal fiber reinforcements 2, with a spacing of 50 to 55 cm. The transverse fiber reinforcements 3 are set obliquely, and the angle between them and the longitudinal fiber reinforcements 2 is 60.5°. Figure 1 and Figure 2 .

[0065] Step 10: Pour the concrete and vibrate it evenly after completion. The corners of the concrete slab should be vibrated with an inserted vibrator first, and then with a flat vibrator. Be careful when vibrating to the position of the basalt fiber reinforcement to prevent the fiber reinforcement from shifting.

[0067] Step 12: Install high-precision infrared temperature monitors, alarm devices and automatic sprinklers on both sides of the road to form an intelligent road temperature control system. Figure 3 .

[0068] Step 13: Combine the pavement intelligent temperature control system to maintain the pavement layer 1, improve the soil roadbed to generate heat under the alkali excitation reaction, accelerate the pavement layer maintenance, cooperate with the pavement intelligent temperature control system, issue an alarm when the temperature is too high, and sprinkle water to cool down.

[0069] The technical solution of the present invention is further illustrated by test examples. The proportion of basalt solid waste improved soil is changed to form Example 2 and Comparative Examples 1-5, and the mechanical properties of the improved soil are represented by unconfined compressive strength. The mass ratio and unconfined compressive strength results are shown in Table 1.

[0070] Table 1 The tests were conducted in accordance with the "Highway Geotechnical Test Code" (JTG3030-2020) and the "Highway Roadbed and Pavement Field Test Code" (JTG3450-2019). Figure 5 and Figure 6 . From the test results in Table 1, it can be seen that for Example 2 and Comparative Examples 1 and 2, the strength of the basalt solid waste improved soil increases with the increase of cement content, but after the cement content exceeds 15% of the basalt, the strength begins to decrease. Compared with Comparative Examples 3 to 4, Example 2 optimizes the ratio of the plain soil, and the strength of the improved soil is significantly improved. Compared with Example 2, Comparative Example 5 changes the ratio of water. The specimens are cured for 6 days at the standard rate. On the 7th day, the specimens disintegrated after being soaked in water, and the strength is 0 MPa, indicating that the water content should not be too high. The improved soil made by the ratio adopted in the present invention has a high strength, reaching 2.74 MPa.

[0071] The technical solution of the present invention is further illustrated by Example 2 and Comparative Examples 6 to 10. A four-point bending test of basalt fiber reinforced road panels was carried out. Figure 7 and Figure 8 , see Table 2 for details, and the test results are shown in Figure 4 .

[0072] Table 2 from Figure 4It can be seen from the test results that, compared with Example 2 and Example 6, optimizing the overlap length can effectively increase the ultimate load and failure displacement of the road panel. Considering comprehensive factors such as cost and construction, the overlap length is determined to be 10 to 12 times the diameter of the fiber reinforcement. For Examples 6, 7, and 8, optimizing the spacing between the fiber reinforcements can effectively improve the mechanical properties of the road panel, but if the spacing is too small, it will affect the pouring of concrete, thereby reducing the strength. After comprehensive consideration, the spacing between the fiber reinforcements is determined to be 20 to 22 cm. Compared with Example 2 and Examples 9 and 10, the greater the distance between the fiber reinforcement and the surface layer, the higher the strength of the road panel, but if the distance is too large, the fiber reinforcement will not be able to play a role in time, thereby reducing the strength of the road panel. After comprehensive analysis, the distance is determined to be 9 to 10 cm.

[0073] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
