Description
Technical Field
The invention belongs to the technical field of road maintenance engineering, and particularly relates to a low rolling resistance road surface sealing layer for reducing tire-road rolling resistance and a preparation method thereof.
Background
"tire-road" rolling resistance is the energy loss that occurs when a rolling tire moves over a road surface, where too high a rolling resistance results in not only loss of traction but also production of more pollutants, and where lower a rolling resistance results in production of pollutants (e.g., CO) 2 And NO X ) The number will decrease. Research shows that the rolling resistance is closely related to the fuel consumption of the vehicle, when the rolling resistance is reduced by 10-20%, the fuel consumption can be reduced by 2.5-3.6% at most, and the fuel consumption reducing effect of heavy vehicles is more obvious. The reduction of the rolling resistance in the running process of the vehicle becomes a necessary technical research in the automobile industry, and simultaneously, the obvious effect is achieved. The tire industry is working on reducing the rolling resistance of tires during operation from the field of tire manufacture, ignoring road effects on the tires.
Research shows that the tire-road rolling resistance has direct relation with the road surface structure, the flatness, the road surface strength and the like, and the better the road surface flatness is, the smaller the tire-road rolling resistance is. The danish researchers noted this detail first and began the study of low rolling resistance road surfaces with some success. The project of 'Energy-Saving road' (Roads Saving Energy) popularized by the danish road administration designs a durable asphalt concrete pavement which can reduce the rolling resistance by 5%, namely a 'low rolling resistance asphalt concrete pavement'. According to the measurement and calculation of related departments in Denmark: the application of the low rolling group asphalt concrete pavement can reduce the fuel consumption of the Danish whole-border traffic equipment operation by about 3.3 percent, and 4800 ten thousand liters of fuel and 4.5 ten thousand tons of greenhouse gases can be saved every year.
The low rolling resistance asphalt concrete pavement realizes the purpose of reducing the tire-road rolling resistance by improving the overall performance of the asphalt concrete pavement and reducing the surface structure depth. However, since the reduction of the road surface structure depth has a certain adverse effect on the anti-slip performance, the research of the low rolling resistance road surface based on the asphalt concrete has a certain limitation. Meanwhile, the newly-built low rolling resistance asphalt concrete pavement project is large in investment, and if the existing road needs to be modified, milling needs to be carried out, so that the rapid popularization is not facilitated.
By 2019, the total mileage of the Chinese highway reaches 484.65 kilometers, and compared with a newly-built low rolling resistance asphalt concrete pavement, the low rolling resistance asphalt concrete pavement has the advantages that the low rolling resistance modification is carried out on the existing pavement, and the function of realizing the low rolling resistance pavement has more practical significance and economic benefit. Suppose that: the oil consumption of the civil vehicle is 8 liters, each vehicle runs 1 kilometre every year, the tire-road rolling resistance is reduced by 5 percent, which is equivalent to saving 1.5 percent of energy consumption, saving 0.12 liter of oil per hundred kilometres, and saving 12 liters of oil per vehicle every year. Based on the automobile reserve volume 372.7 ten thousand in Shenzhen 2021, if the low rolling resistance transformation can be applied to the Shenzhen road network in a large scale, the fuel consumption of 4472 ten thousand liters can be reduced every year in Shenzhen city, and the method has great economic benefit and environmental benefit.
Road surface texture is the most important characteristic indicator that determines the interaction between the tire and the road surface, such as friction, noise, hydroplaning, tire wear, rolling resistance, etc. The world road association divides road surface features into 4 scales of roughness, macro texture and micro texture from large to small according to the wavelength, amplitude, power spectrum characteristics of the road surface structure and possible influence on road users.
The decision research on the anti-skid recovery technology of the asphalt pavement based on the texture characteristics of the road surface, which is applied to Jiangyan university, shows that the texture structure of the formed pavement belongs to negative texture as the conventional asphalt concrete pavement needs to be rolled in the construction process. Under the characteristic of the negative texture, the larger the macroscopic texture, the better the skid resistance of the pavement, but the larger the rolling resistance of the pavement.
The positive texture structure is a structure with more prominent skid resistance, as shown in fig. 1, and is used for reducing the texture structure of the road surface as much as possible on the premise of ensuring skid resistance, so that the effective balance between the skid resistance and the rolling resistance of the road surface can be achieved.
As shown in fig. 2, the gray scale processing by scanning the photograph for different road surface structures is used to intuitively reflect the difference between different road surface texture configurations. According to the invention, the anti-skid aggregate with a specific particle size is matched with a certain amount of the binding material, so that a uniform, fine and compact road surface structure with positive texture can be formed compared with an asphalt concrete road surface, a micro-surfacing part, a gravel seal layer and the like.
Disclosure of Invention
In order to achieve the road surface function of reducing the tire-road rolling resistance by simply reconstructing the existing road surface, the invention provides a low rolling resistance road surface sealing layer for reducing the tire-road rolling resistance and a preparation method thereof.
The technical scheme adopted by the invention is as follows: a low rolling resistance road surface seal for reducing tire-road rolling resistance comprises an original road surface, a first epoxy asphalt seal, a second epoxy asphalt seal, a third epoxy asphalt seal and a seal; the original pavement, the first epoxy asphalt seal layer, the second epoxy asphalt seal layer, the third epoxy asphalt seal layer and the seal layer are sequentially paved from bottom to top, wherein the original pavement, the first epoxy asphalt seal layer, the second epoxy asphalt seal layer and the third epoxy asphalt seal layer are paved by adopting a synchronous sprinkling/spreading process; the sealing layer is paved by adopting a spreading technology.
A preparation method of a low rolling resistance pavement sealing layer for reducing tire-road rolling resistance comprises the following steps:
the method comprises the following steps: paving a first epoxy asphalt seal layer on the original pavement by adopting a synchronous sprinkling/spreading process;
step two: after the first epoxy asphalt seal layer is dried and solidified, a second epoxy asphalt seal layer is paved by adopting a synchronous sprinkling/spreading process;
step three: after the second epoxy asphalt seal layer is dried and solidified, a third epoxy asphalt seal layer is paved by adopting a synchronous sprinkling/spreading process;
step three: and after the third epoxy asphalt seal layer is dried and solidified, paving the seal layer by adopting a spraying process.
Further, the first epoxy asphalt seal layer is composed of anti-skid aggregate and binder;
wherein the anti-skid aggregate has a particle size of 2-3 mm or 1-2 mm;
the adhesive material is one of 1.0-1.8 kg/square meter of water-based epoxy asphalt or 0.5-1.0 kg/square meter of oil-based epoxy asphalt;
the anti-skid aggregate is selected from one of carborundum, basalt particles and ceramic particles, and the dosage is 2.0-4.0 kg per square meter.
Further, the second epoxy asphalt seal layer is composed of anti-skid aggregate and binder;
wherein, the anti-skid aggregate is one of anti-skid aggregates with the grain diameter of 2-3 mm or 1-2 mm;
the adhesive is one of 0.6-1.3 kg of water-based epoxy asphalt per square meter or 0.3-0.7 kg of oil-based epoxy asphalt per square meter;
the anti-skid aggregate is selected from one of carborundum, basalt particles and ceramic particles, and the dosage is 1.5-2.5 kg per square meter.
Further, the third epoxy asphalt seal layer is composed of anti-skid aggregate and binder;
wherein, the anti-skid aggregate is selected from anti-skid aggregate with the grain diameter of 1-1.5 mm or 0.5-1 mm;
the adhesive is one of 0.6 to 1.2kg of water-based epoxy asphalt per square meter or 0.3 to 0.6kg of oil-based epoxy asphalt per square meter;
the anti-skid aggregate is selected from one of carborundum, basalt particles and ceramic particles, and the dosage is 1.4-2.0 kg per square meter.
Furthermore, the sealing layer is made of one of 0.5-0.8 kg of water-based epoxy asphalt per square meter or 0.2-0.4 kg of oil-based epoxy asphalt per square meter.
Different construction processes and aggregate grain sizes have different influences on the anti-skid performance and the tire-road rolling resistance reduction of the formed thin-layer pavement structure.
The anti-skid property and the tire-road rolling resistance of different thin-layer pavement structures are researched by using anti-skid aggregates with different particle sizes and through different forming processes (rolling and non-rolling forming).
The test result shows that: in the aspect of the anti-skid property of the pavement, the thin-layer pavement structure of the sand material (0-0.5 mm) has poor anti-skid property and less practical engineering application; the anti-skid performance of the thin-layer pavement structure formed by rolling small-particle-size aggregates (0.5-2 mm) and large-particle-size aggregates (2-8 mm) is obviously lower than that of the thin-layer pavement structure which has the same particle size and is not rolled, which is the same as the research result of Jiangmen Bighua anti-skid recovery technology decision research on asphalt pavement based on road surface texture characteristics.
In the aspect of tire-road rolling resistance, the tire-road rolling resistance of a thin-layer pavement structure with large-particle size aggregates (2-8 mm) is obviously reduced after rolling, but the influence of the rolling of the thin-layer pavement structure with small-particle size aggregates (0.5-2 mm) on the tire-road rolling resistance is not obvious; the tire-road rolling resistance of the non-rolled (0.5-2 mm) thin-layer pavement structure of the small-particle size aggregate is obviously lower than that of the rolled (2-8 mm) thin-layer pavement structure of the large-particle size aggregate.
According to the research result, in order to achieve the balance of low rolling resistance and skid resistance of the pavement, a forming process of small-grain-size aggregate (0.5-2 mm) and non-rolling needs to be adopted, and the small-grain-size epoxy asphalt seal layer just meets the above conditions.
Therefore, the present invention has the following advantages.
