What are standard conditions for aggregate testing established by IDOT?

The standard conditions for aggregate testing established by IDOT focus on temperature, humidity, and curing conditions. These parameters are crucial for ensuring that test results are consistent and reliable, reflecting the performance of the aggregate under typical field conditions.

Temperature affects the physical properties of the aggregate and can influence factors such as moisture absorption and the effectiveness of bonding agents during the curing process. Humidity plays a significant role in moisture content determination, which is vital for accurate testing outcomes. Curing conditions are essential for simulating the environment that aggregates will encounter in actual construction scenarios, ensuring that the testing reflects real-world applications.

The other options include factors that may be relevant in different contexts (such as chemical composition or pressure) but do not represent the standard conditions set by IDOT for aggregate testing. Standardizing these specific conditions helps in achieving uniformity across tests, leading to better quality assurance in construction practices.
