Introduction of Stripping Value Test on Aggregates

The Stripping Value Test is used to determine the stripping value of an aggregate. The test is conducted by mixing the aggregate with water and allowing it to stand for a period of time. The aggregate is then removed from the water and allowed to dry. The stripping value is the percentage of the original dry weight of the aggregate that is lost during the test.

Objectives of Stripping Value Test on Aggregates

  • The stripping value test on aggregates is carried out to determine the loss in mass of fine aggregate particles when they are subjected to the action of water
  • The test is carried out in order to assess the suitability of aggregates for use in concrete or asphalt pavements
  • The test is also used to determine the resistivity of aggregates to stripping in pavements.

Apparatus Required in Stripping Value Test

  • A stripping value test is used to determine the amount of bitumen that can be extracted from an asphalt cement using a solvent
  • The test is conducted by weighing a known quantity of asphalt cement, adding a solvent to the asphalt cement, and then extracting the bitumen from the solvent
  • The bitumen is then weighed and the percentage of bitumen extracted is calculated
  • The apparatus required for a stripping value test includes an asphalt cement, a solvent, a beaker or flask, a graduated cylinder, a balance, and a spatula.

The procedure of Stripping Value Test on Aggregates

  • One of the most important tests for aggregates is the stripping test
  • The stripping test measures the loss of binding between the aggregate and the paste when the two are exposed to water
  • This test is important because it gives an indication of how the aggregate will perform in concrete that is exposed to moisture.

    To perform the stripping test, a small sample of aggregate is placed in a container of water

  • The container is then agitated for a period of time, typically 10 minutes
  • After the agitation period, the aggregate is removed from the water and the loss in mass is determined
  • The loss in mass is then divided by the original mass of the aggregate to determine the stripping value.

    The stripping value is an important measure of the durability of an aggregate

  • Aggregates with high stripping values are more likely to cause problems in concrete that is exposed to moisture.

Precautions Taken in Stripping Value Test

  • There are a few key precautions to take when performing a value strip test:

    1

  • Always test in a well-ventilated area.

    2

  • Wear gloves and protective eyewear.

    3

  • Follow the manufacturer’s instructions carefully.

    4

  • Be sure to Neutralize the area afterwards to prevent corrosion.

Conclusion

The Stripping Value test on aggregates is a new test that has been developed to help engineers and contractors alike to determine the suitability of an aggregate for use in hot mix asphalt. The test is simple to administer and provides clear and concise results. The test can be used to examine the potential for an aggregate to cause stripping of the asphalt binder from theaggregate surface. The test is conducted by adding a small amount of asphalt binder to the aggregate and then mixing the two together. The mixture is then placed in an oven and heated to a specified temperature for a specified period of time. After the specified time has elapsed, the mixture is removed from the oven and cooled. The cooled mixture is then examined to determine the percentage of
