Asphalt surface heating apparatus which has a body, rubber wheels and heating member units (20a, 20b, 21a, 21b, 21c, 21d, 30) consisting of heating members that have been placed next to one another in groups for heating an object to be heated, such as the asphalt surface of a road or other area so that the old asphalt material present in the asphalt surface can be milled and removed, wherein the heating apparatus can be brought into a heating position and into a transport position, in which - in the heating position, at least some of the heating member units (21a, 21b, 21c, 21d) protrude outside the body of the heating apparatus and heat the asphalt surface within an area as large as possible, and - when brought into the transport position, at least some of the heating member units (21a, 21b, 21c, 21d) have been turned in relation to the body of the heating apparatus to reduce the size of the heating apparatus so that the heating apparatus can be transported on a public road on the rubber wheels, wherein the asphalt surface heating apparatus includes - at least one heating member unit (20a, 20b) located below the body, - side heating member units (21a, 21b, 21c, 21d) located on the sides of the body, which, in the heating position, are arranged as an extension of the heating member units (20a, 20b) located below the body on the sides of the heating apparatus and, in the transport position, are turned upright along the sides of the body, and - a movable heating member unit which can be turned, with a lifting device located at the back of the body, into the heating position, behind the body, as an extension of the heating member unit located below the body, characterized in - that the movable heating member unit can be turned, with the lifting device located at the back of the body, into the transport position on top of the body, - that the movable heating member unit attached to the back of the body of the asphalt surface heating apparatus includes a centre part attached to the lifting device and, on both its sides, two side parts (32a, 32b, 33a, 33b), which have been attached to one another with joints, allowing the adjacent parts to turn into a perpendicular position in relation to one another, and - that, in the heating position of the heating apparatus, the side parts (32a, 32b, 33a, 33b) located on both sides of the movable heating member unit have essentially been turned horizontal so that, together with the centre part, placed on the same level, they form a heating member unit, the width of which is essentially equal to the combined width of the heating member unit (20a, 20b) located below the body of the asphalt surface heating apparatus and the side heating member units (21a, 21b, 21c, 21d) located on both its sides in the heating position, and - that, in the transport position of the heating apparatus, the side parts (32a, 32b, 33a, 33b) of the movable heating member unit have been turned on top of its centre part and the movable heating member unit has been turned on top of the body of the heating apparatus. - in the heating position, at least some of the heating member units (21a, 21b, 21c, 21d) protrude outside the body of the heating apparatus and heat the asphalt surface within an area as large as possible, and - when brought into the transport position, at least some of the heating member units (21a, 21b, 21c, 21d) have been turned in relation to the body of the heating apparatus to reduce the size of the heating apparatus so that the heating apparatus can be transported on a public road on the rubber wheels, wherein the asphalt surface heating apparatus includes - at least one heating member unit (20a, 20b) located below the body, - side heating member units (21a, 21b, 21c, 21d) located on the sides of the body, which, in the heating position, are arranged as an extension of the heating member units (20a, 20b) located below the body on the sides of the heating apparatus and, in the transport position, are turned upright along the sides of the body, and - a movable heating member unit which can be turned, with a lifting device located at the back of the body, into the heating position, behind the body, as an extension of the heating member unit located below the body, - that the movable heating member unit can be turned, with the lifting device located at the back of the body, into the transport position on top of the body, - that the movable heating member unit attached to the back of the body of the asphalt surface heating apparatus includes a centre part attached to the lifting device and, on both its sides, two side parts (32a, 32b, 33a, 33b), which have been attached to one another with joints, allowing the adjacent parts to turn into a perpendicular position in relation to one another, and - that, in the heating position of the heating apparatus, the side parts (32a, 32b, 33a, 33b) located on both sides of the movable heating member unit have essentially been turned horizontal so that, together with the centre part, placed on the same level, they form a heating member unit, the width of which is essentially equal to the combined width of the heating member unit (20a, 20b) located below the body of the asphalt surface heating apparatus and the side heating member units (21a, 21b, 21c, 21d) located on both its sides in the heating position, and - that, in the transport position of the heating apparatus, the side parts (32a, 32b, 33a, 33b) of the movable heating member unit have been turned on top of its centre part and the movable heating member unit has been turned on top of the body of the heating apparatus.
