Research Report 126 Surfacing for high stress areas

Published: | Category: Activity management , Research programme , Research & reports | Audience: General

Data consisting of levels of scabbing (chip loss) of rating sections of New Zealand state highway chipseals, together with a seal stress classification calculated from the road geometry, were collected and analysed to look for relationships between seal type, seal stress classification and susceptibility to scabbing.

The data indicates that there is no evidence of seal designers adjusting the seal type to accommodate for high stress sites.

There is a clear hierarchy of seal types as regards susceptibility to scabbing, but no relationship could be found for the proposed stress classification system.

Keywords: Chipseal, scabbing, ravelling
