Embodiment 1

[0031] Pothole disease is the most common disease on asphalt pavement, and it is also the maintenance object with the largest number of pavement minor repair and maintenance operations, and it is also the most difficult type of disease to deal with; this is due to the small scale of pothole repair and low degree of mechanization; on the other hand It is because the construction time is limited and the interface is difficult to handle in place; therefore, the quality of pothole repair is often not guaranteed, and the probability of secondary damage in situ after repair is very high.

[0032]The detailed treatment of the boundary of the pothole repair process is the most easily overlooked process step, and it is also the most difficult part to achieve the expected effect. It is affected by subjective and objective factors such as the quality of emulsified asphalt, the performance of hand-held sprayers, and the degree of attention of personnel. There is no simple and reliable boun...

Embodiment 2

[0038] In the typical semi-rigid base asphalt pavement structure in China, a sealing layer needs to be set between the semi-rigid base and the asphalt concrete surface to prevent the road surface from seeping into the dense cement-stabilized gravel layer, thereby reducing the occurrence of pumping and subsidence on the pavement and other serious structural damage.

[0039] At present, the construction of asphalt pavement seal is mainly realized by on-site processes such as slurry seal and hot asphalt surface treatment. Due to the influence of current technology and material properties, neither of the two processes can achieve satisfactory results.

[0040] The ultra-thin bituminous film of the present invention is used as the sealing layer of the pavement engineering, and the specific use method is: spread a layer of 0.6mm ultra-thin asphalt film on the cement-stabilized gravel layer, and then spread a layer of 160 mm on the ultra-thin asphalt film. ℃ of asphalt mixture, that ...

Embodiment 3

[0044] Waterproof membrane is a kind of sheet-like impermeable material made of asphalt and tire core. The thickness is generally about 3mm. Its waterproof effect and durability mainly depend on the quality of the membrane itself and the bonding status of the membrane and the building. . At present, the construction of waterproof membrane mainly adopts flame spraying device to grill the membrane itself, and bond it to the top surface of the building when the asphalt on the surface melts. As mentioned above, the heating uniformity of this kind of process is not suitable to be controlled, and two workers are required to cooperate. operation, and because the thickness of the coil itself is large, the required heating time is long and the heating energy consumed is high.

[0045] Use the pure asphalt ultra-thin asphalt film of the present invention as the waterproof membrane interface adhesive (made of high-grade asphalt with a smaller heat capacity, usually with a thickness of 0....

Abstract

The invention relates to an ultra-thin asphalt film for engineering interface treatment and a using method for the ultra-thin asphalt film, and belongs to the field of building materials. The ultra-thin asphalt film is prepared from different kinds of asphalt and asphalt products, can meet technical requirements of waterproof roll interface glue, asphalt pavement seal coat and an asphalt pavement bonding layer by virtue of different performance indexes. The ultra-thin asphalt film is paved to an engineering interface part, is externally heated to construct through a flame or hot-air heating device, and is quickly fused to bond with the surface of a structure. The material and the method have the technical characteristics of saving energy resources, being controllable in quality, and being simple and convenient to construct, and are beneficial improvement and expansion of an existing engineering interface treatment technology.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an ultra-thin asphalt film for interface treatment in the field of highway engineering and waterproof engineering and its application method. Background technique [0002] In the construction and maintenance of asphalt pavement, the water sealing effect and bonding effect inside the pavement structure are important details that affect the performance of the pavement. Excellent sealing and adhesive layers can significantly reduce the occurrence of water-related diseases on the asphalt pavement and improve the pavement Structural mechanical properties, thereby improving the bearing capacity of the pavement and prolonging the service life of the pavement. [0003] In terms of sealing materials, the water sealing layer is an important pavement structure setting to prevent water seepage from the road surface and reduce road pits and slurry diseases. At present, the constr...
