As per Indian Road Congress (IRC) the stripping value of aggregate sho...
The stripping value of aggregates is determined as the ratio of the uncovered area observed visually to the total area of aggregates, expressed as a percentage. If the road aggregates are dry and free from dust then the bitumen adheres well to all normal types of aggregate. In the absence of water there is practically no problem of adhesion with bituminous construction. Adhesion problem occurs when the aggregate is wet and cold. This problem can be dealt with by removing moisture from the aggregate by drying and increasing the mixing temperature. Further, the presence of water causes stripping of binder from the coated aggregates. This problems occur when bitumen mixture is permeable to water.
Static immersion test is one specified by IRC and is quite simple. As per Indian Road Congress (IRC) the stripping value of aggregate should not exceed 5% for the use in bituminous surface dressing, penetration macadam, bituminous macadam, and carpet construction when aggregate coated with bitumen is immersed in water bath at 48oC for 24 hours.

Stripping Value of Aggregate According to IRC
According to Indian Road Congress (IRC), the stripping value of aggregate should not exceed a certain value when it is used in bituminous surface dressing, penetration macadam, bituminous macadam, and carpet construction. The stripping value is determined by immersing the aggregate coated with bitumen in a water bath at a specific temperature for a specific duration.
Values of X, Y, and Z
The values of X, Y, and Z depend on the type of construction and the expected performance of the pavement. The correct values for the specified types of construction are:
- X = 5%
- Y = 40°C
- Z = 24 hours
Explanation
The stripping value test is used to determine the adhesion between the bitumen and the aggregate. If the adhesion is poor, the bitumen film will separate from the aggregate surface, and the pavement will fail. The stripping value is expressed as the percentage of the coated aggregate retained after immersion in water.
IRC has specified the maximum stripping value for different types of construction to ensure the durability and performance of the pavement. For bituminous surface dressing, penetration macadam, bituminous macadam, and carpet construction, the maximum stripping value should not exceed 5%.
The test temperature and duration are also specified by IRC. The test should be conducted at 40°C for 24 hours to simulate the real-world conditions that the pavement will experience.
Conclusion
In summary, the stripping value of aggregate should not exceed 5% for bituminous surface dressing, penetration macadam, bituminous macadam, and carpet construction according to Indian Road Congress (IRC). The test should be conducted at 40°C for 24 hours to determine the stripping value.
