ABSTRACT:
The present spreading apparatus for road construction mixtures, such as bituminous cold mixtures, has at least two V- or U-shaped screeding structures or screeds one leading and the other trailing with respect to the working direction. The leading screed extends tandemly, partially into the angle formed by the trailing screed. The leading screed structure has a worm type conveyor connected parallel to each wall of the V- or U-shaped screed. The worm type conveyor assures the homogenity of the road construction mixture and reduces the inherent pressure of the mixture against the leveling elements. Both the leading and the trailing screed are adjustably inclined away from the working direction. The adjustment of the screed position may be made, for example, by a spindle with a hand wheel.
