Sick road why "permanently"? After a long period of use and rolling mill, the road surface will crack, carbuncle package, subsidence and other diseases. Director of Municipal Facilities Supervision Department Huo Tiejian said that the above-mentioned disease is caused by the long-term uneven stress of the cement stabilization layer, which is a normal physical phenomenon after long-term use of the road. Responsible for urban road maintenance work of the municipal construction group executive vice president of Meng said the whole,[url=http://roadcuttingmachine.com/blog/3286.html]Operational Safety Of Road Thermal Spray Gun[/url] to solve such problems usually only a minor road surgery, "removal of lesions" can be. That is, to remove the asphalt and concrete structures of the pavement, re-lay the roadbed and pave the asphalt. Meng Lingquan said that each year before the opening of the Peony Culture Festival, they urban road disease in the centralized conservation and found that many diseases pavement, "every year to treat sick every year." To this end, the municipal facilities supervision and municipal construction group of experts conducted a number of field research, experts found that the disease pavement, usually taken by local cutting repair method, the past to fill the "wound" with the new asphalt pavement Old asphalt does not achieve real bonding, cutting the existence of cracks in the section, encountered rain and snow days, the water will penetrate the cracks along the roadbed, and quickly destroy the surrounding embankment. After the car grinds, the road surface will appear the crack, the collapse and so on more serious disease. Colloid asphalt "bandage" to prevent the wound and then "infection" So, how to solve this problem? In 2012, the city for the elimination of road cracks using asphalt grouting technology, the width of the cracks in the road with a slotting machine cut into about two centimeters wide gap, and then use the high pressure dust removal machine in the gap of garbage, Gap filled asphalt (commonly known as "potting"). Meng said the whole for the filling of the asphalt used in colloidal asphalt, can penetrate the small gap, and play the role of adhesion,[url=http://roadcuttingmachine.com/blog/3406.html]Imported Machinery Asphalt Heating Plate[/url] the equivalent of the road "wound" wrapped in a circle of "bandage." The city road maintenance, the relevant departments in the reference fill "potting" this method, based on the old and new asphalt pavement at the junction of the "glue" approach "to heal" disease, which can effectively prevent the rain, Dust penetration into the gap, causing new damage to the roadbed to ensure that the treated pavement in 3 years without disease. This technology is the city's first, has been widely used in urban areas road repair and maintenance work. The conservation work will be completed by April, the public during the trip in the face of conservation workers in the sealing operation,[url=http://roadcuttingmachine.com/blog/1471.html]emulsified asphalt sprayer practical tips[/url] as far as possible to bypass the operating surface access, so as to avoid the car tires will be taken away the road gel.
