The aggregate impact value indicates a relative measure of the resistance of the aggregate to a sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load. From the calculations done we know that the aggregate can be acceptable as their Aggregate Impact value is less then 20% Aggregate Impact Value 10.

The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.

We determined that an indicator of Ukraine's external state debt per 1 person in 2017 amounted to 2,744 USD, exceeding the maximum permissible limit more than 10 times. We noted that one of the actual threats to the national security of Ukraine is the ineffective management of the state debt. Conclusions.
