| Asphalt road is the main operating Nowadays our country roads, road transport more than 50% of the volume of asphalt road through to the finish. The volume of asphalt road maintenance works Large wide asphalt road with the conservation project of road construction machinery adapted to demand. Microwave heating uniformity of heating technology, control a timely manner, the superiority of non-polluting and so on, used in hot asphalt pavement on-site renewable sources to meet the high-grade highways "into the Express, Express homework, rapid withdrawal" of the job requirements will be able to obtain considerable economic benefits and significant social benefits.In this paper, the Asphalt Pavement Maintenance Truck microwave heating to achieve the main function - heating the wall of waveguide arrays, through simulation, testing, made a homework for heating the wall of the flared waveguide, improve the microwave power density, and through mobile achieve dynamic heating heating wall, improve heating uniformity, can reduce the heating time and lower power consumption. New type of metal wall heat shield installed Net-chain structure of the implementation, enhance the service life of the microwave shielding devices, improved shielding chain network installation, maintenance conditions. |
