Microwave Heating Characteristics of Emulsified Asphalt
Emulsified asphalt needs to be cured for a certain age after demulsification to produce strength, which seriously affects the traffic opening time. In this work, microwave heating technology was applied for emulsified asphalt repair materials. Steel slag with high microwave activity was adopted to improve the performance of Steel slag, a by-product of steelmaking, imposes lots of negative impacts on the environment. For alleviating negative impacts, more and more experiments have been carried out to explore the application possibility of steel slag.

Optimizing asphalt mixtures to be heated by microwave
Fig. 1. Asphalt mixtures heating. 3.2 Electrical resistivity The electrical resistance of the asphalt mixtures was measured with the two-probe method by using a megohmmeter with 5 ranges (50 V-1000V). The asphalt specimen, with a thickness of ~4 cm was placed between two copper plate electrodes with dimensions 15 x① Asphalt layer was removed from the steel deck plate as a large piece of plate and no injury was given to the plate. ② Noises generated through the IHIR work process were mainly due to the generator’s work and a wedge bucket’s contact with the steel deck plate, but no noise was generated from striping work.Noiseless In-Place Removing Using Induction Heating System of Asphalt
