Abstract
This study focuses on the applicability of new technology to accurately quantify aggregate stockpiles. As part of the investigation, the study was divided into three phases. The first phase encompassed a literature review of different technologies currently employed by various departments of transportation (DOT) across the country to measure stockpiles. Furthermore, interviews with varying maintenance crews from the Nevada Department of Transportation (NDOT) and other states belonging to the Western Association of State Highway and Transportation Officials (WASHTO) provided insight into the regional methodology. It was found that both an accurate volume estimation and a realistic unit weight factor determination are crucial to quantify a stockpile. Thus, the second phase involved the laboratory testing of sampled aggregates to determine their physical properties and correlation with the unit weight. After the research and laboratory sections were completed, it was decided that implementing an iOS-based application named Stockpile Reports was suitable for NDOT’s needs. Thus, the third phase aimed to compare the current NDOT methodology against this new alternative with a significant focus on measurement accuracy, data-collection time, and user adaption to the latest technology.
