PROBLEM TO BE SOLVED: To provide an expansible screed plate heating means capable of switching the heated part of an expansible screed plate according to the width of pavement. SOLUTION: The whole of a main screed plate 30A is heated by an induction coil 34A. The expansible screed plate 30B is individually switched and heated on the left side by an induction coil 34B<SB>1</SB>and on the right side by an induction coil 34B<SB>2</SB>. An expansible screed plate 30C is individually switched and heated on the left side by an induction coil 34C<SB>1</SB>and on the right side by an induction coil 34C<SB>2</SB>.
