Introduction Surface Engineering Aggregates and Pavement Management

Introduction Surface Engineering & Aggregates and Pavement Management 1

Surface Engineering & Aggregates • Responsible for: • Pavement Management – Maintaining the departments pavement management system and identifying rehabilitation needs • Standards for pavement design – Assist regions in reviewing pavement designs, do some designs in-house. • Construction Standards – Most technical construction standards related to roadways • Aggregates – Work with regions to manage aggregate needs to support department construction program 2

Pavement Management • Overview of Pavement Management • Performance monitoring and data collection – Review of latest developments for pavement distress • Process of developing PM sections • Identify pavement rehab needs • Connect to other systems for programming • Workflow and Roles 3

Pavement Management • Overview of Pavement Management Network Inventory Update Inputs Data Collection – Condition, As-built Analysis Inputs Needs & Treatment Analysis Prioritization Analysis Outputs PMS, Inventory Reports Analysis Reports 4
