Recycled materials in pavement | Sustainability VictoriaSwinburne University investigated the use of recycled crushed glass (5mm minus glass fines) as a supplementary material with recycled concrete aggregates in cement treated bound pavement appliions. This project resulted in VicRoads updating their specifiions.
PCC Recycling – Pavement InteractiveSome general conclusions about RCM material properties from NCHRP Synthesis 154: Recycling of Portland Cement Concrete Pavements (Yrjanson, 1989 [2]) are:. Aggregate particle aggregate particles produced by crushing have good particle shape, high absorptions, and low specific gravity compared with conventional mineral aggregates.
