The world's first microwave road maintenance vehicle was unveiled in Guangzhou

a report recently released by international market analysis agency Smartech, "plastics in the 3D printing Market: 10-year opportunity forecast", said guide: besides being used to heat food, microwaves can also be used to heat roads? This sounds like a fantasy. Yesterday morning, I witnessed the scene of using microwave technology to repair the road surface in Kaiyuan avenue of Guangzhou Development Zone.

besides heating food, microwaves can also be used to heat roads? This sounds like a fantasy. Yesterday morning, I witnessed the scene of using microwave technology to repair the road surface in Kaiyuan avenue of Guangzhou Development Zone

although it has only been built for threeorfour years, the asphalt pavement on Kaiyuan Avenue has cracked to varying degrees. I saw a 78 square meter microwave heating wall protruding from a container car like maintenance car. Under its heating, hard asphalt had white smoke in less than 10 minutes. About 20 minutes later, the heating wall will automatically move away. At this time, the temperature of the asphalt has reached about 130 degrees Celsius, and the cracked road surface has been completely softened. The workers can shovel the road surface with a few light shovels with a shovel, and evenly lay the softened asphalt on the road surface. Finally, the workers use the small road compactor brought by the maintenance vehicle to compact the asphalt. Within an hour, the cracked road was repaired

according to the person in charge of the site, this is the world's first asphalt pavement maintenance equipment using the principle of microwave heating, with a value of more than 1 million yuan. One workflow is completed, and it is invested and developed by Weite company under Midea Group. It has completely independent intellectual property rights, breaking the monopoly of engineering machinery technology in the maintenance industry in Europe, America and Japan. As the development trend of repairing asphalt pavement, thermal regeneration has also experienced the development process from traditional fire baking to microwave heating. The equipment applies thermal regeneration technology to avoid the shortcomings of heavy pollution, low efficiency and poor repair quality of the traditional manual pavement excavation and repair. It can recycle the asphalt, and the warranty of a single repair can be one to two years. This is also the first field application of Guangdong's scientific and technological achievements during the 11th Five Year Plan in Guangzhou Development Zone

friendship is multifunctional and low consumption, which provides great impetus and development space
