Paving process

Abstract

A pavement paving process including incorporating a rejuvenator in a layer of compacted millings to yield a layer of rejuvenated layer; and compacting a layer of aggregate over the layer of rejuvenated layer to protect the layer of rejuvenated layer and to cause the layer of aggregate to at least be partially infused with the layer of rejuvenated layer.

What is claimed herein is: 
     
         1 . A pavement paving process comprising:
 (a) incorporating a rejuvenator in a layer of asphalt millings to yield a layer of rejuvenated asphalt millings; and   (b) compacting a layer of aggregate over said layer of rejuvenated asphalt millings to protect said layer of rejuvenated asphalt millings and to cause said layer of aggregate to at least be partially infused with said layer of rejuvenated asphalt millings.   
     
     
         2 . The pavement paving process of  claim 1 , wherein said layer of asphalt millings comprises compacted asphalt millings. 
     
     
         3 . The pavement paving process of  claim 2 , wherein said rejuvenator is configured to be applied at a rate of about 0.05-0.07 gallon per cubic yard of said compacted asphalt millings. 
     
     
         4 . The pavement paving process of  claim 1 , wherein said layer of asphalt millings comprises millings of about 0.5-3.0 inches. 
     
     
         5 . The pavement paving process of  claim 1 , wherein said layer of aggregate comprises crushed stone of about 0.25-3.0 inches. 
     
     
         6 . The pavement paving process of  claim 5 , said crushed stone comprises a stone selected from the group consisting of limestone, granite, basalt, quartz, sandstone and any combinations thereof. 
     
     
         7 . The pavement paving process of  claim 1 , wherein said compacting step is configured to be performed within about 1 hour of the start of said incorporating step and any one of said layer of rejuvenated asphalt millings and said layer of aggregate is disposed at at least about 70 degrees F. 
     
     
         8 . The pavement paving process of  claim 1 , wherein said incorporating step comprises spraying said layer of asphalt millings. 
     
     
         9 . A pavement paving process using asphalt millings, said process comprising:
 (a) incorporating a rejuvenator in a layer of the asphalt millings in a compacted form to yield a layer of rejuvenated asphalt millings, wherein said rejuvenator is configured to be applied at a rate of about 0.06 gallon per cubic yard of the layer of the millings; and   (b) compacting a layer of aggregate over said layer of rejuvenated asphalt millings to protect said layer of rejuvenated asphalt millings and to cause said layer of aggregate to at least be partially infused with said layer of rejuvenated asphalt millings.   
     
     
         10 . The pavement paving process of  claim 9 , wherein the asphalt millings comprise millings of about 0.5-3.0 inches. 
     
     
         11 . The pavement paving process of  claim 9 , wherein said layer of aggregate comprises crushed stone of about 0.25-3.0 inches. 
     
     
         12 . The pavement paving process of  claim 11 , said crushed stone comprises a stone selected from the group consisting of limestone, granite, basalt, quartz, sandstone and any combinations thereof. 
     
     
         13 . The pavement paving process of  claim 9 , wherein said compacting step is configured to be performed within about 1 hour of the start of said incorporating step and any one of said layer of rejuvenated asphalt millings and said layer of aggregate is disposed at at least about 70 degrees F. 
     
     
         14 . The pavement paving process of  claim 9 , wherein said incorporating step comprises spraying said layer of the asphalt millings in a compacted form. 
     
     
         15 . A pavement paving process using asphalt millings, said process comprising:
 (a) incorporating a rejuvenator in a layer of compacted millings to yield a layer of rejuvenated layer, wherein said rejuvenator is configured to be applied at a rate of about 0.05-0.07 gallon per cubic yard of asphalt millings; and   (b) compacting a layer of aggregate over said layer of rejuvenated layer to protect said layer of rejuvenated layer and to cause said layer of aggregate to at least be partially infused with said layer of rejuvenated layer,   wherein said compacting step is configured to be performed within about 1 hour of the start of said incorporating step and any one of said layer of rejuvenated asphalt millings and said layer of aggregate is disposed at at least about 70 degrees F.   
     
     
         16 . The pavement paving process of  claim 15 , wherein the asphalt millings comprise millings of about 0.5-3.0 inches. 
     
     
         17 . The pavement paving process of  claim 15 , wherein said layer of aggregate comprises crushed stone of about 0.25-3.0 inches. 
     
     
         18 . The pavement paving process of  claim 17 , said crushed stone comprises a stone selected from the group consisting of limestone, granite, basalt, quartz, sandstone and any combinations thereof. 
     
     
         19 . The pavement paving process of  claim 15 , wherein said incorporating step comprises spraying said layer of compacted millings.
