Description

Bridge deck paving and bridge paving the paving block and processing method of the paving block

Technical field

The invention relates to a bridge deck and a processing method of the paving, and to a bridge paving the paving.

Background technique

The steel bridge is beneficial to alleviate the dead load and the characteristics of the space structure, and is the preferred structural form of the large span bridge. However, the steel bridge deck is characterized by smoothness, flexibility, large local deformation, complex dynamic characteristics and small heat capacity, all of which impose strict requirements on the bridge deck pavement. Existing steel bridge deck pavements, regardless of cast asphalt concrete (GA), asphalt mastic concrete (MA), modified asphalt (SMA), epoxy resin asphalt (EA), premature high temperature rutting, lateral displacement, cracking Other diseases, these diseases are not only related to the unfavorable use conditions of steel bridge deck pavement, but also directly related to the traffic conditions in China, but the key is that the various structures of pavement GA, MA, SMA, EA can not meet the steel bridge deck Functional requirements: good fatigue resistance to cracking, excellent high temperature stability, perfect water and drainage resistance, good interlayer bonding performance, good followability with steel sheet deformation, good flatness and anti-slip performance, as much as possible Small appropriate thickness (to reduce structural weight).

According to incomplete statistics, at present, the domestic large-span highway bridge has completed the steel bridge deck pavement area of only 2 million square meters. In the past 20 years, the research and practice of Chinese steel bridge deck pavement has not stopped. However, the problem of steel deck pavement has not been effectively solved so far. From the technical level, the steel box girder is a large thin-walled space structure. Under the action of temperature and load, the steel box girder will undergo deformation such as elongation, shortening, bending, partial downward deflection and torsion. Deck paving requires the ability to follow the steel box girder for cooperative deformation. On the other hand, the bridge deck pavement directly bears the wheel load rolling, the bridge deck pavement needs to resist the local deformation caused by the wheel load, and the steel bridge deck pavement is required to keep the appearance smooth and easy to drive. This contradictory demand determines the technical complexity of steel deck pavement engineering. Coupled with the phenomenon of heavy-duty vehicles that are common in China's highways, this undoubtedly exacerbates the complexity of contradictions. Steel bridge The surface pavement structure and materials and choices have not only been a difficult point and a hot technical issue in the construction of highway engineering in China, but also an unsolved problem in the international arena.

At present, steel bridge decks in all countries of the world basically adopt asphalt concrete systems. The steel bridge deck pavement structure mainly has the following four categories: 1 Casting asphalt concrete GA (Guss Asphalt) structure represented by Germany and Japan. The thickness of the general German cast asphalt concrete is 2×35mm, and the Japanese 35mm cast asphalt concrete. +30mm modified dense grade asphalt concrete; Mstic Asphalt structure represented by the United Kingdom (actually cast asphalt concrete, but the pavement thickness and process are different from those in Japan), generally 38mm The main disadvantages of pouring asphalt concrete are: low temperature stability and easy formation of ruts; construction requires a series of special equipment, and the construction organization is more complicated; the temperature of the mixture during construction is very high, reaching 240 °C or above, and the impact on the bridge cannot be ignored. . Cast steel deck pavement technology is suitable for countries and regions with low summer temperatures, such as Germany, the United Kingdom, and Northern Europe. Cast-in-place steel deck pavement technology is also widely used in Japan. 2)Stone Mastic Asphalt recently adopted in Germany and Japan, the main disadvantage of modified asphalt SMA: Modified asphalt SMA is widely used in pavement structure, but through the application survey of completed steel bridge, The application effect of modified asphalt SMA in steel bridge paving is not ideal. There will be different degrees of rutting, partial crowding, shifting, oil flooding and local fatigue cracking soon after the pavement is opened. The double-layer SMA is applied in the early stage in China. For a long time of use, the bridge deck pavement of some bridges has been seriously damaged, and various forms of damage have been manifested. Due to the poor crack resistance of SMA materials using SBS asphalt, cracking is one of the most common diseases of double-layer SMA paving, and there are also ruts, pits, and displacements on the bridge deck. 3 Epoxy asphalt concrete structure represented by the United States, with a total thickness of 32-76mm epoxy asphalt concrete (EA). The main disadvantages are: the price of epoxy asphalt is high, and the key technologies are controlled by large foreign companies. The preparation process of epoxy asphalt mixture is complicated; the time and temperature requirements in the construction of epoxy asphalt mixture are very strict, the construction environment is demanding and the construction is difficult. Epoxy asphalt pavement has a long curing time and is difficult to repair. At present, there is no repair method for the damage of epoxy asphalt. Epoxy asphalt pavement has a smooth surface and a small macroscopic structure depth, especially in rainy days. The main problem that occurs in epoxy asphalt paving is construction control, and the lack of construction control is the main reason for pavement damage. The flexibility is inferior to the asphalt material, and the bridge deck pavement is prone to cracking and other diseases; since the epoxy asphalt pavement layer is impervious to water, the residual moisture inside the construction layer is likely to cause the paving layer to be bulged, if not effective. The processing will further develop into a pit. There is no good way to repair the epoxy asphalt pavement. After re-paving after milling, it takes a long time to maintain the health, which has a great impact on traffic. The repairing construction often succumbs to the traffic pressure and ultimately affects the repair effect.

The steel bridge deck pavement is generally composed of anti-rust layer, adhesive layer and asphalt mixture pavement layer, which is directly laid on the top of the steel box girder with a total thickness of 35-80mm. Due to the special conditions of use conditions, construction technology, quality control and requirements of steel box girder deck pavement, it has high strength, fatigue resistance, rutting resistance, shear resistance and deformation coordination. It is required that China has not yet formed a universally valid steel bridge deck pavement design theory and method.

At present, there are three steel bridge pavement structures that are the most commonly used in the world and are considered to be the best in the industry. Structure 1: Double-layer modified SMA domestic early steel bridge deck pavement often adopts this structure. The main diseases are cracking, pits, ruts and shifts. Structure 2: Cast asphalt concrete (GA) + high elastic SMA. Due to the high-elastic asphalt SMA used in the upper layer, the disease type is similar to that of the double-layer SMA. Structure 3: Double layer US epoxy asphalt concrete. Since 2008, many steel bridge decks using American epoxy asphalt concrete paving technology have begun to appear diseases and defects. The common diseases of epoxy asphalt steel bridge deck paving are: bulging, cracking, pits and so on. The problem is also becoming more and more prominent, and at one time there seems to be no recognized paving technical solution. Due to the special conditions of use conditions, construction technology, quality control and requirements of steel bridge deck pavement, its strength, fatigue resistance, rutting resistance, shear resistance, seismic performance and deformation coordination are different. Requirements for use on the roadbed.

So far, the development of domestic steel bridge decking has gone through three stages. From 1997 to 2002, with the Humen Bridge as the representative, it actively introduced foreign advanced paving technology. The technologies introduced and promoted during the period were: double-layer SMA concrete, British cast asphalt concrete and American double-layer Epoxy asphalt concrete and other technologies, but all have delamination and disease. From 2002 to 2008, the first two technologies appeared problems in engineering applications, and the US epoxy asphalt concrete technology represented by Nanjing Second Bridge began to be applied. Since 2008, many steel bridge decks using American epoxy asphalt concrete paving technology have also begun to appear diseases and defects. The industry has lost confidence in the US epoxy asphalt concrete paving technology, and the steel bridge deck pavement problem Increasingly prominent, there seems to be no recognized paving technical solution for a time. It can be seen that the use of bridge deck asphalt pavement for large-span steel bridges in China is not ideal, and there is still a lack of successful experience in steel deck pavement. In addition, the service life of foreign steel bridge decks has never exceeded 30 years.
