Due to the large traffic volume, some sections of Xiyan Expressway expansion joint The concrete of the protection belt is broken and collapsed, resulting in the overall settlement of the entire expansion joint belt. The traditional method is to use asphalt Or ordinary concrete is used to fill the holes, but the asphalt adhesion is poor, and the compressive strength is low. The holes will appear in less than a month. Repeated repair has caused great trouble to citizens' travel, which wastes both manpower and financial resources.
After comprehensive investigation and comparison, it was decided to use the high-tech new material "Emergency Repair Treasure RT-2" produced by Xi'an Ruitai New Material Co., Ltd., which has been widely used in the national municipal, high-speed, airport, and has solved the problems of holes and fractures in bridge pavement and bridge expansion joints, and diseases of concrete roads for many years. The repaired roads and bridges are stable and high, and have been unanimously recognized by customers.
The core technical advantages of this product and its effect after trial repair:
(1) Short open traffic time: the road can be opened to traffic after 2-4 hours of maintenance after construction, completely solving the traffic jam problem.
(2) Good adhesiveness: the bonding parts are tightly connected.
(3) High flexural and compressive strength: the flexural and impact strength is more than 3 times that of ordinary concrete; The pressure resistance is more than 20 times higher than that of asphalt, and the pavement under heavy load will not fall off or crack.
(4) The construction is simple and convenient, and the comprehensive cost performance is good.
(5) High durability: greatly improve the pavement quality, reduce traffic accidents caused by road conditions, and facilitate people's travel.
(6) The beauty is not affected: the color after repair is basically the same as that of the road surface.
The rush repair treasure RT-2 rapid repair material developed and produced by Xi'an Ruitai New Material Co., Ltd. can be solidified in 30 minutes and opened to traffic in 2 hours. It not only has the advantages of waterproof and frost resistant products, but also has the characteristics of high compressive strength, high early strength, and no backward strength in the later period. It effectively solves the disease of municipal road damage in Huaihua, Hunan Province, alleviates the traffic pressure and improves the municipal cement The beauty, service life and wear resistance of concrete pavement help customers solve the problem of road disease repair, and provide reliable guarantee for the smooth traffic environment of the road.
