Abstract
Construction inspection plays a pivotal role in ensuring the quality and long-term performance of infrastructure products. INDOT is currently facing the challenge to effectively train novice inspectors and update experienced inspectors with the latest versions of quality requirements to perform construction inspection effectively and more efficiently. This project developed a digital inspection training system to train INDOT inspectors to inspect asphalt pavement construction. Inspectors can access the inspection instructions through a construction process-based approach or a pay item-based approach. The inspection guidance is developed using data and information from INDOT’s Standard Specification (2024), Manual for Frequency of Sampling and Testing and Basis for Use of Materials, General Instructions to Field Employees, Standard Drawings, risk-based check items developed in previous JTRP projects (SPR 4002 and SPR 4422), INDOT training materials, and relevant external references from Federal Highway Administration, state transportation agencies, and reports of National Cooperative Highway Research Program (NCHRP) projects. The system is implemented through a Web platform. It serves as a training tool for novice inspectors and a quick reference for experienced inspectors seeking update-to-date specifications and guidelines.
