Amp-100 waterproof coating for bridge deck used in the special waterproof project of Datong Road and Bridge in Shanxi

Shanxi Datong Road and Bridge Waterproof Special Use of amp-100 Deck Waterproof coating

The handover and acceptance of Changzhi Linfen Expressway is imminent November 5, 2018

On November 5, the reporter learned from Shanxi Road and Bridge Construction Group Co., Ltd. that on November 2, the handover and acceptance meeting of Changzhi Linfen Expressway was held in Linfen City. The handover and acceptance working group was composed of relevant units and relevant persons, such as the Provincial Department of Transport, the Key Points Office of the Provincial Department, the Provincial Bureau of Transport Quality Supervision, the Provincial Senior Management Bureau, Shanxi Traffic Control Group, Shanxi Road and Bridge Group, etc, After three days of intensive work, it was unanimously recognized that the project of Changling Linzhou Expressway was qualified for handover and acceptance, and the project was handed over for acceptance.

　　 With a total length of 166.234km, the Changlin Expressway Project is an important part of Qingdao Lanzhou Expressway in the national expressway network in our province, and it is also the tenth horizontal in the backbone of Shanxi's "three vertical, twelve horizontal and twelve ring" expressway network. The main line adopts the standard design of four lane expressway, and the design speed is 100km/h. The project starts from Tunliu County, Changzhi City, connects Taichang Expressway and Changhan Expressway from east to west, passes Tunliu and Changzi in Changzhi and Anze, Gu County, Hongdong, Yaodu and Xiangfen in Linfen, seven counties (districts) in two cities, to Xiangfen County, Linfen City, connects Linji Expressway and Dayun Expressway, and connects Shaanxi, Gansu and Ningxia provinces.

　　 After the opening of the Changsha Linzhou Expressway Project, from a national perspective, it will open up the last section of the "dead end road" of the State Grid Qingdao Lanzhou Expressway in our province, become the main highway to the sea in Gansu, Ningxia, Shaanxi, Shanxi and other central and western regions, and connect the eastern coastal developed areas and the western economically underdeveloped areas, which will improve the national expressway network and give play to the network effect, It is of great significance. From the perspective of the whole province, the Taihang Mountain Tourist Attraction and the Yellow River Tourist Attraction will form a regional tourist route of "Taihang Culture", "Ancestor Culture", "Yao Culture" and "Yellow River Culture" because of this highway, so as to help the development of tourism in our province and provide "traffic support" for the construction of a new pattern of tourism development in the whole region.

　 The opening of the whole line of Changzhi Linfen Expressway has shortened the opening time of Changzhi and Linfen from four hours to one and a half hours, breaking the history of Anze and Guxian without expressway exits, and promoting the economic development of the two counties.

AMP-100 second-order reactive deck waterproofing coating

Product introduction:

AMP-100 second-order reactive waterproof coating for bridge deck One component black modification asphalt Waterproof coating It can integrate the foundation road (bridge) and road (bridge) surface into a whole, forming a high elastic improved plastic bearing, waterproof and shear resistant whole, thus greatly improving the performance of roads, bridges and roads, and extending the service life of roads and bridges, especially heavy loaded roads on steep curves, to more than 13 years

AMP-100 second-order reactive waterproof adhesive contains permeable materials, which can penetrate into the 3mm~5mm high level of the gross pores of the road and bridge pavement concrete. After curing, it can not only repair the micro defects of the road and bridge pavement concrete, but also plug the capillary water seepage holes of the road surface, playing an excellent waterproof effect; Penetrate and form nail effect, firmly adhere to cement Concrete surface course It can effectively prevent delamination and peeling of the waterproof layer, and is not easy to be damaged by construction vehicles and paving equipment and cause water leakage.
Reaction curing function: the initially cured waterproof bonding layer is subject to high temperature (higher than 100 ℃) under the action of asphalt pavement concrete, micro melting distribution will occur. Under the action of rolling, large aggregate particles will be embedded in the waterproof bonding layer, forming a uniformly distributed shear force key ； After cooling, a good elastic plastic waterproof bonding layer is generated The cohesion is further improved, and the shear strength and bond reach more than 1.0Mpa at the same time. The lower cement concrete and the asphalt concrete of the surface layer are integrated into a stressed whole.

Construction Procedure

1. Foundation surface treatment before construction
New concrete bridge deck shall at least 7 day curing period, sand blasting and roughening are recommended.
（ 1) Firstly, the bad attachments on the road surface shall be removed, and the sand particles and sundries on the road surface shall be cleaned. The places with oil stains shall be specially treated, which can be dissolved by solvent;
（ 2) After the road is cleaned, sand blasting machine is used for sand blasting, so as to remove laitance on the road and some sundries that are not firmly attached, and make the road cleanliness and roughness meet the requirements;
（ 3) The interface can be completely purged and dried by professional hair dryer.

2. Base surface treatment
Cement concrete required The surface shall be dry and clean, free of laitance, pollutants, looseness, peeling, hollowing and serious cracking, and the interface shall be completely dry.

3. AMP-100 scattering
