摘要： A spreader box for spreading cold mixed asphaltic concrete paving mixtures including a supporting frame or "bridge" attached to a left and right side plate. Within the spreader box and at the front portion of the box is situated a left and right side hydraulic motor or other power means, which is used to power a left and right side auger for lateral distribution of the paving mixture. Adjustment means on each end and in the middle to allow for vertical adjustment of the distribution auger. A left and right side "ROLLING SCREED" roll which has an adjustment means on each end and in the middle to allow for vertical adjustment of depth of spread.A left and right side compression roll which has adjustment means at each end and in the center for vertical adjustment of down pressure. Screed roll and compression roll connected by chain and sprocket or other power transfer means. One or more wheels or caterpillar tracks are mounted on each side plate.
