Composition of Mixture: |

Stripping Test: |
Immediately after mixing, the mixture shall meet the requirements of
ASTM 1664, whereby not more than 5% of the aggregate particles shall
remain uncoated.
|
5.
Storing or Stockpiling: |
Immediately following the production of the WESPRO product the material
should be allowed to cool down to ambient temperature before loading
out or placement in repair areas. The stockpile can be however large
you decide is best for space requirement. Also, in case of inclement
weather, such as rain, during the period while material is still above
ambient temperature it would be best to cover material to ensure stripping
does not take place.
It is normal for
a crust to form on the exterior of the stockpile due to the product
characteristics, but the interior will remain pliable and ready to use
along with the crust when blade mixed together.
|
6.
Handling Precautions: |
In handling of WESPRO Asphalt Patching Material normal industry-wide
safety precautions such as the prevention of cigarette smoking, and
any other form of ignition or combustion, should be strictly adhered
to
