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
