The pre-determined temperature is close to the temperature of the fresh hot asphalt to be applied. An asphalt paver travels behind the seam sealer and applies fresh hot asphalt to the road surface still to be paved, overlapping it onto the previously laid down asphalt in the seam area. The fresh hot asphalt and the previously laid down asphalt form a molten mass, which is subsequently pressed to a smooth, fused and finished road surface by a road roller. | 01-28-2010 |
