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

Pavement Management• Identify pavement rehab needs – factors
considered
– Road class, traffic
– Current/predicted performance
– Treatment history
– Pavement strength
– Safety and other local concerns
– Department PPS Guidelines
– Ranking based on need year and Cost-Effectiveness
