The recycled asphalt maintains a high temperature until
right before it is compacted. Hot-welded joints between old and new paving
materials create incredible adhesive strength, which prevents the rehabilitated
pavement from cracking. |
|
|
Excess moisture is effectively removed from recycled material making quality
control simple. |
|
|
Old asphalt can be recycled in accordance with any ordered specification. |
|
|
Recycled asphalt can be comparable to new asphalt. High assessment is obtained
from engineers of official organization in Canada and the United States. |

Adhesion between the repaired layer and the layer below is
imperfect due to insufficient heating. Cracks in the lower
layer may eventually lead to cracking of the repaired layer.
|
|
Hot in-place maintenance enables complete adhesion between
the repaired layer and the layer below it. This reduces recurrence
of cracks in the repaired layer.
