There are a type having only a pair of screeds, a type having a pair of screeds, and a type further having a pair of telescopic screeds each having an elastic function, but in the present example, the former will be described. A first embodiment of an asphalt finisher of the present invention will be described with reference to FIGS. 1 and 2. The structure of the other parts not explained is almost the same as the conventional asphalt finisher described in the section of the prior art,
The repeated description is omitted by using the reference numerals given in FIGS. 3 and 4. The asphalt finisher of this example is used for constructing a relatively narrow road. This asphalt finisher moves along the center line of the main body 1 and the center line of the road surface with the center line of the road surface aligned with each other, and can pave the entire width in the width direction of the road orthogonal to the moving direction in one run. .

The screeds 10 are arranged symmetrically with respect to the center line of the main body which is parallel to the traveling direction, and are arranged along the width direction of the road surface (the lateral direction in FIG. 1, the direction perpendicular to the paper surface in FIG. 2). The total width of the pair of screeds 10, 10 is substantially equal to the width of the road surface to be paved. In other words, the asphalt finisher can pave a road surface having a width corresponding to the width of the pair of screeds 10, 10 by a single construction.

If such a posture is set, the road surface spread by the screed 10 can be made a medium-high gradient road surface having a high central portion. For example, the width is 1250 mm and the height of the center is 30 mm compared to the road edge.
Consider a case where a road surface with a high medium-high slope is constructed at once using the asphalt finisher. In such a case, the inside of each screed 10 may be lifted to incline each screed 10 with respect to the horizontal plane by an angle θ = tan −1 (30/625).
