Description
Technical Field
The invention relates to a preparation and spraying method of a hydrophobic bonding layer material between double-layer drainage asphalt pavement layers, belonging to the technical field of pavement of road engineering.
Background
The drainage asphalt pavement is in a skeleton gap structure, coarse aggregates are tightly connected with each other to form mutually embedded and extruded skeletons, the porosity is larger and is generally about 18-25%, and the structural depth is larger. The rapid discharge of the road surface accumulated water also greatly reduces the formation of water mist and water films, the splashing of wet road surfaces and the road surface reflection to improve the visibility during driving, reduce the occurrence rate of traffic accidents and improve the driving safety and comfort.
In addition, the asphalt pavement receives solar energy, converts the radiation energy of the sunlight into internal energy, stores the internal energy in the road surface layer, and transmits the internal energy downwards in a heat conduction mode. Due to the high porosity, the heat conduction contact area between layers is greatly increased, according to a Fourier heat transfer formula, the heat conduction effect is better than that of a common pavement, the heat conduction amount is high, and the temperature change of a pavement surface layer is large, so that the porous asphalt pavement can also be effectively cooled, and the urban heat island effect is solved. Noise sound waves generated when vehicles pass are easily absorbed by large gaps on the road surface and converted into heat energy to be weakened, and the heat energy is continuously refracted to cause loss when the noise sound waves are transmitted between the gaps and tires, so that the noise is reduced. But porous bituminous paving paves, the use in, along with the effect of driving load, dust blocks up and the change of environmental conditions such as rainfall, vegetation, the void fraction can constantly descend, causes the space decay, leads to the drainage performance decay, and the function greatly reduced of making an uproar falls in the cooling.
The drainage asphalt pavement originates from Europe, and is popularized and used all over the world due to the characteristics of good pavement performance, noise reduction and the like. The drainage asphalt pavement is divided into a single-layer drainage pavement and a double-layer drainage pavement, and the single-layer drainage asphalt pavement is poor in noise reduction effect and easy to be blocked by broken stones and dust, so that the drainage performance is sharply reduced, and the service life is short. Therefore, more countries have conducted studies on double-layer drainage asphalt pavement: the upper layer is a skeleton gap structure consisting of finer gradations, mainly plays a role in filtering, filters some dust and gravels on the road surface to prevent the dust and gravels from blocking the lower layer of mixed material, and usually PAC-10 is used as the upper layer; the lower layer is a skeletal void structure composed of a coarser grading, which primarily functions to drain water and remove a small portion of the debris falling from the upper layer, and PAC-16 is commonly used as the lower layer. The problem that the drainage effect of the drainage pavement is lost due to the fact that the pavement is blocked can be effectively solved after the double-layer drainage asphalt pavement is adopted, the upper layer can effectively filter many impurities, dust and the like, the drainage effect of the pavement after the pavement is blocked for a period of time is poor, the impurities in pores of the upper layer can be sucked through the vacuum pump, and the pavement drainage performance can be greatly improved after the impurities are cleaned at intervals.
However, the double-layer drainage asphalt pavement has high requirements on the construction process, the upper and lower surface layers need to be well combined, and meanwhile, the strength and the fluidity of the lower surface layer are ensured during paving, otherwise, the pavement performance of the pavement and the reasonable distribution of the upper and lower surface layers cannot be met. The construction process of the double-layer drainage asphalt pavement is mainly divided into two types of layered paving and simultaneous paving. The simultaneous paving refers to the simultaneous paving of an upper surface layer and a lower surface layer, and the simultaneous paving has great advantages only by using one paving machine to synchronously pave the lower surface layer and the upper surface layer, but has higher requirements on construction instruments, and the machinery of China is not popularized yet, so that the paving is mainly carried out by using a cold and hot layered paving construction mode. The layered paving is to pave the lower surface layer first and then pave the upper surface layer after the lower surface layer is cooled and formed.
When the double-layer drainage asphalt pavement is paved in a layered mode, the phenomenon of weak adhesion between an upper layer and a lower layer exists, emulsified asphalt is sprayed to serve as an adhesion layer when an upper layer mixture is paved, and the upper layer asphalt mixture is paved after the emulsified asphalt is demulsified. The bonding layer prepared from the common emulsified asphalt has weak bonding force between the upper surface layer and the lower surface layer after being used, and the bonding layer has a barrier effect on water seepage, so that the water seepage performance of the lower surface layer of the drainage pavement is reduced, the water seepage speed is reduced, and the pavement drainage is not smooth.
Therefore, the invention improves the adhesion performance of the common asphalt by modifying the common asphalt, improves the adhesive force between the upper layer and the lower layer, fully utilizes the hydrophobic effect to modify the asphalt, and can quickly seep water drops in the adhesive layer.

The invention aims to provide a preparation and spraying method of an interlayer hydrophobic bonding layer material of a double-layer drainage asphalt pavement, and solves the problems of low bonding strength, slow moisture permeation speed and unsmooth drainage of the double-layer drainage asphalt pavement between the upper surface layer and the lower surface layer of the conventional double-layer drainage asphalt pavement.
(2) Technical scheme
The technical problems that the bonding strength between the upper surface layer and the lower surface layer of the existing double-layer drainage asphalt pavement is low, the drainage performance loss of the double-layer drainage pavement is reduced, the drainage performance is improved and the like are solved. The invention firstly selects the hydrophobic agent with stable molecular structure, excellent performance and better compatibility with the emulsified asphalt according to the application range of the bonding layer, and then provides a preparation and spraying method of the interlayer hydrophobic bonding layer material of the double-layer drainage asphalt pavement according to the preparation flow and the construction process of the emulsified asphalt. The technical scheme of the invention is as follows: adding styrene-butadiene-styrene block copolymer (SBS) and high-viscosity modifier into molten matrix asphalt, fully swelling and grinding to obtain high-viscosity SBS modified asphalt, adding cationic emulsifier, stabilizer, hydrochloric acid and the like into distilled water to prepare soap solution, sequentially pouring the soap solution and the high-viscosity SBS modified asphalt into a preheated colloid mill, carrying out high-speed shearing and stirring until no segregation and agglomeration phenomena exist to obtain high-viscosity SBS modified emulsified asphalt, adding organic silicon rubber particles and interfacial agent, carrying out high-speed shearing and stirring to obtain hydrophobic high-viscosity SBS modified emulsified asphalt, finally spraying hydrophobic high-viscosity SBS modified emulsified asphalt on the surface of the lower layer of a clean, smooth and dry double-layer drainage pavement, after the emulsified asphalt is completely demulsified, preparing an interlayer bonding layer of the double-layer drainage asphalt pavement, paving an upper layer asphalt mixture of the double-layer drainage asphalt pavement, the bonding strength and the moisture permeation speed between the upper surface layer and the lower surface layer of the double-layer drainage asphalt pavement are improved, and the drainage performance of the double-layer drainage asphalt pavement is improved.
(3) Advantageous effects
The drainage asphalt pavement has better social benefit, and the double-layer drainage asphalt pavement has greater advantages than the single-layer drainage asphalt pavement. However, when a double-layer drainage road surface is constructed, the double-layer drainage road surface cannot be directly paved due to condition limitation, and the problems that the upper surface layer and the lower surface layer cannot be well combined, the water seepage speed of the lower surface layer is reduced, drainage is not smooth, and pores inside the double-layer drainage road surface are blocked due to the bonding layer can be caused by the method of paving the lower surface layer firstly and paving the upper surface layer after the lower surface layer is formed. The invention provides a preparation method and a spraying method of a hydrophobic bonding layer material between double-layer drainage asphalt pavement layers, and the hydrophobic high-viscosity SBS emulsified asphalt sprayed on the lower surface layer of the double-layer drainage asphalt pavement has very important practical significance for improving weak bonding between the upper and lower surface layers of the double-layer drainage pavement, reducing the loss of drainage performance between the upper and lower surface layers and improving the drainage performance of the double-layer drainage asphalt pavement.
