4. If density testing results are below minimum requirements, submit proposed corrective action to Engineer.

1.06 FIELD OR SITE CONDITIONS

A. Place asphaltic mixture only on a prepared, firm, and compacted base, foundation layer, or existing pavement substantially surface-dry and free from loose and foreign material. Do not place pavement over frozen subgrade or base, when roadbed is unstable or during rain or snow.

B. Cold Weather Paving

1. Remove Subsections 450.3.2.1.1(1) of the State Specifications and replace with the following:

Asphaltic pavement shall not be placed when the air temperature in the shade and away from artificial heat sources is less than 36 ̊ F. If Engineer allows placing asphaltic mixtures below the specified minimum temperature, either at the Contractor’s request or to complete the Work to the stage the contract requires, the Work will be performed at the Contractor’s risk. Final inspection of the asphaltic concrete pavement will be deferred until May of the following year. Before final acceptance of the Work, restore all pavement damage or defects the Engineer attributes to temperature or other weather conditions. Repair or replace areas of pavement as identified by the Engineer.

C. Wet Weather Conditions
