Which procedure is used for determining the weight loss of cores?

The Core Drying Procedure is essential for determining the weight loss of asphalt cores because it involves a systematic method of drying the cores to achieve a constant weight. This procedure allows for accurate measurement by ensuring that any moisture within the core is removed, which can otherwise skew the weight measurements. By using this method, you are able to establish a true weight baseline for the core material, allowing for effective analysis of the asphalt’s properties and its performance characteristics.

In the context of the other choices, the Core Cooling Procedure does not focus on weight loss but instead deals with temperature management after extraction from the pavement. Core Additive Analysis examines the components or additives in the asphalt mix rather than assessing weight changes. Lastly, Core Integrity Evaluation is aimed at assessing the structural condition of the core, not its weight or moisture content. Therefore, the Core Drying Procedure is the appropriate choice for determining weight loss, as it directly addresses the need to measure the core’s weight accurately after moisture removal.
