ABSTRACT:
A road surface heating apparatus for repairing a deteriorated asphalt paved road includes an air shut out device with skirt members surrounding the heating panel so as to prevent air from entering into the heating apparatus, thereby restraining smoke generation. The generated smoke is filtered and purified by an after-burner and a catalyst burner and then exhausted, thus air pollution problems at the work site are solved.
