Research Report 574 Geosynthetics in basecourse stablisation

Published: | Category: Activity management , Research programme , Research & reports | Audiences: Road controlling authorities, Road traffic engineers & consultants, Roading contractors

The application of geosynthetics (ie geogrids) for the stabilisation of basecourses prepared with a River Run rounded gravel aggregate was investigated. Reductions in the rate of rut formation by over 50% were observed when geogrids were included either at the basecourse/sub-base interface or at half-height of the basecourse. The rate of rut formation was reduced further if a square type geogrid was used in place of a triaxial type geogrid. It was found that the basecourse rutted rapidly if the surface was not confined, due to the lack of particle interlock and surface confining stress. If the surface was confined with a thin (ie < 40mm) asphalt layer to bind together the particles in the surface, then the aggregate provided significant support and reduced rutting by over 90%, even without the addition of geosynthetic stabilisation.

Roading data quality reports – South Waikato District

Published: | Category: Waikato Region , RCA data quality , Research & reports | Audiences: Local & regional government, Road controlling authorities, Road traffic engineers & consultants, Roading contractors

These reports are the result of Road Efficiency Group’s (REG) annual assessment of the South Waikato District Council’s ONRC and asset management (AM) data quality. The 2017/18 ONRC data quality framework consists of 35 metrics and the asset management data quality framework consists of 31 metrics. These metrics interrogate the South Waikato District Council’s RAMM and Transport Investment Online (TIO) data for completeness, accuracy and timeliness. Each report includes a summary of the metric results by dimension and category plus for each metric it shows how the South Waikato District Council is positioned against what’s considered good (the expected standard) and where the sector sits. The metrics in the framework have been selected to test a cross section of the data underpinning the ONRC Performance Measure results and our decision-making processes. An individual metric result is intended to raise a red flag when not at the expected standard.
