Detailed Description
The present invention will be described in detail with reference to fig. 1 to 3, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a drainage and noise reduction asphalt concrete implementation road surface by improvement, which comprises a drainage asphalt road surface structure and a drainage and noise reduction asphalt road surface edge structure; the drainage asphalt pavement structure comprises a drainage asphalt mixture layer 1, a dense-graded asphalt mixture layer 2, a lower sealing layer 3, a base layer 4 and a road bed 5. Wherein drainage nature pitch miscella 1 is the drainage functional layer, and close-packed asphalt mixture 2 is well, lower floor, has waterproof bonding layer between 1, 2, and lower seal 3 forms the lower floor of close-packed asphalt mixture 2, has closely knit waterproof to have stronger anti rutting performance.
The thickness of the drainage asphalt mixture layer 1 is 4-5 cm.
The asphalt concrete implementation road surface for drainage and noise reduction, and the edge structure embodiment 1 of the asphalt concrete implementation road surface for drainage and noise reduction; as shown in fig. 2, the concrete backfilling device comprises backfilling soil 6, wherein a C20 concrete precast block 7 is arranged at the top of the backfilling soil 6, a phi 40mmPVC-U pipe 8 is embedded below the C20 concrete precast block 7, and C15 large-pore drainage concrete 9 is arranged on the side surface of the C20 concrete precast block 7.
The asphalt concrete implementation road surface for drainage and noise reduction, and the edge structure embodiment 2 of the asphalt concrete implementation road surface for drainage and noise reduction; as shown in fig. 3, the macadam blind ditch 10 comprises a non-woven geotextile filter 11 arranged at the bottom of the macadam blind ditch 10, a phi 10cm soft permeable pipe 12 is pre-embedded, a C20 concrete body 13 is poured at the upper end of the macadam blind ditch 10, and a reinforced concrete cover plate 14 is correspondingly arranged.
When the drainage and noise reduction asphalt pavement is constructed, in order to facilitate drainage, the elevation of a drainage facility (the joint part of the drainage facility and the asphalt surface layer) can be lowered to be lower than or flush with the elevation of the surface of the middle surface layer, so that rainwater can be smoothly drained out of the pavement. Considering the particularity of the drainage function of the drainage asphalt pavement, 10cm drainage gaps are reserved at intervals of 10m on the kerbstones so as to ensure the range of rainwater drainage road width in the drainage asphalt pavement.
For a roadbed filling road section, the elevation of the roadbed shoulder filling is flush with the top surface of the middle surface layer, and rainwater can be discharged through gaps on the side surfaces of the road surface. For the square digging section and the road surface super high section, the connection between the drainage asphalt road surface and the existing drainage system is needed to be made.
The drainage noise reduction asphalt pavement firstly needs to break through the problems of removing accumulated water on the pavement during precipitation and preventing surface water leakage. The key to solving this problem is to provide a good waterproof adhesive layer. At present, most of pavement structures are semi-rigid base asphalt pavements, a plurality of technical measures for reducing base cracking do not achieve good effects, and the base cracking phenomenon exists all the time. The waterproof bonding layer generally has better extensibility, and the bonding strength between the surface layer and the middle layer of the drainage asphalt mixture can be enhanced by arranging the waterproof bonding layer, because the contact area between the surface of the drainage asphalt mixture and the lower layer of the drainage asphalt mixture is reduced by 15 to 20 percent compared with that of a dense-graded asphalt mixture. In addition, road surface water can be prevented from permeating to the middle and lower surface layers and the base layer, and water damage is prevented.
In the actual construction process, a proper amount of waterproof bonding layer material is usually spread on the middle surface layer to increase the waterproof effect. It should be noted that the drainage noise reduction asphalt pavement is different from the adhesive layer oil spread in the construction of the middle surface layer of general asphalt concrete, the waterproof bonding layer of the drainage noise reduction asphalt pavement is matched with the mixed material with the density adaptive to the density of the middle surface layer to jointly form a waterproof layer, the waterproof effect is exerted, and meanwhile, the spreading of the waterproof bonding layer enables the middle surface layer and the upper surface layer to be combined more tightly, and each layer of the pavement to be firmer. In the research, the influence factors of the interlaminar shear strength and the tensile strength are respectively analyzed according to the interlaminar direct shear strength and the direct drawing strength, so as to provide theoretical guidance for the design of the waterproof bonding layer of the drainage pavement.

The invention has the following characteristics;
1. the structure of the drainage edge of the drainage bituminous pavement shoulder is optimally designed, and water can be drained away in time in rainy days.
2. The interlaminar shear strength shows the trend of increasing and then decreasing, and the dosage of the viscous layer oil of the maximum shear strength is 0.8kg/m2Left and right. When the vertical pressure is increased to 0.7MPa, the change amplitude of the interlaminar shear strength along with the increase of the using amount of the viscous layer oil is relatively small.
3. The shear strength between the asphalt pavement layers is gradually increased along with the increase of the vertical pressure. However, under different temperature conditions, the shear strength of the composite material is increased in different magnitudes, and the influence of the vertical pressure on the interlayer shear strength is larger as the temperature is higher. Under the action of vertical tensile force, the interlayer shear strength is reduced sharply, and the interlayer shear strength is smaller along with the increase of the vertical tensile force.
4. For the mechanical property of the adhesive layer, the SBS modified asphalt shows the optimal shear resistance under the temperature condition of 25 ℃, and then the normal asphalt and the cation emulsified asphalt are sequentially used.
5. With the increase of the dosage of the viscous layer oil, the tensile strength shows the rule of increasing firstly and then reducing. After the horizontal thrusts with different magnitudes are acted, the optimal dosage of the interlaminar tensile strength is slightly different, but compared with the optimal dosage determined by the shear strength in the prior art, the optimal dosage determined by the tensile strength is larger than the optimal dosage determined by the shear strength.
7. With the increase of the dosage of the viscous layer oil, the oblique shearing strength shows a trend of increasing first and then decreasing. In addition, the optimal dosage of the sticky layer oil is different under different temperature conditions, and the optimal dosage of the sticky layer oil is lower when the temperature is higher. The oblique shearing strength is the same as the direct shearing strength, has strong temperature sensitivity, and the oblique shearing strength is rapidly reduced along with the increase of the temperature.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
