Percentage of asphalt binder. Degree of compaction. Quality control.Abstract
Despite the different approaches to defining quality, it is understood that minimizing the variability of the main characteristics of a product or process provides a gain in quality. For this purpose, it is necessary to first measure such variability. Aiming to add greater quality to asphalt pavement works, this study describes and statistically compares the variations that occur during the plant mixing and compaction stages of dense asphalt mixtures in three real road construction projects, with the percentage of asphalt binder (%Pb) and the degree of compaction (DoC) as quality indicators for each stage, respectively. For the works under analysis, the results indicate variations intrinsic to the type of service, but also reveal a scenario of normative non-conformities and significant statistical differences among the variations observed throughout construction, indicating a potential for improvement in the process. The proposed statistical approach adds a quantitative understanding of the execution process and can be used by contractors to improve their procedures aiming at quality improvement. Additionally, when applied to works already completed and/or in progress, regulatory agencies acquire useful references to assist in the planning and implementation of compliance audits in an optimized and precise manner.
