Paving method and paving machine

摘要

Paving materials having excellent durability supplied to a front spreading screw 5 is prevented from dropping onto the center band of a road by a bottom plate 30, and by the rotation of the front spreading screw 5 is spread onto the two bands of the road where the left and right tires of cars make contact. In contrast, an ordinary paving materials supplied to rear spreading screw 7 is prevented from dropping onto the bands of the road with which the left and right tires of cars make contact by means of the bottom plates 32, 33 and is spread onto the center band and the outside bands of the road by the rotation of the rear spreading screw 7. Two types of paving materials spread and formed into alternating bands in this way are laid and paved at the same time by the screed 9, and as a result, a pavement with high durability can be constructed at low cost. <IMAGE>
