Research Report 655 Performance benefits of polymer modified bitumen binders for thin surfacings

Published: | Category: Resilience and security , Research programme , Research & reports | Audience: General

Research was undertaken at WSP Opus Research in 2018 to investigate evidence from field studies supporting the performance benefits of polymer modified binders (PMBs) in thin asphalt and chipseal road surfacings. Improved performance benefits claimed for the use of PMB modified thin surfacings include reduced rutting and fatigue cracking in dense asphalt, reduced chip loss in chipseals and open graded porous asphalts and reduced flushing in seals.

Research Report 652 Assessment process for the condition of unsealed roads

Published: | Category: Resilience and security , Research programme , Research & reports | Audience: General

Unsealed roads remain the backbone of the New Zealand’s economy. Less than 40% of local roads in New Zealand are sealed, yet most of New Zealand’s farm produce, important tourism and forestry harvest start their journey to the international market on unsealed roads. It is therefore essential to plan the investment into this network based on appropriate data.
