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
