Jämförande provning – ballast 2015: flisighetsindex, korndensitet och kulkvarn

This report shows results, some statistical analysis and precision data for profiency testing (round-robin) performed on three materials of aggregate during 2015. The properties that was determined was Flakiness Index (EN 933-3), particle density...

Effect of Groundwater Table Rising on the Performance of a Swedish- Designed Gravel Road

Sweden has a wide network of gravel roads. When the water table levels rise during the freeze-thaw and wet seasons, the bearing capacity of the roads will decrease and rut depths increase. The road will suffer a small deterioration every time a...

Jämförelse mellan mekaniska egenskaper och nedbrytning av hjullast: del 2

To study the correlation between the degradation of unbound base layer and mechanical properties (primarily Los Angeles test but also micro Deval test) a number of materials has been exposed by wheel load of VTI’s Heavy Vehicle Simulator (HVS). The...

HVS-test för skattning av nedbrytningseffekter från den tunga trafikens belastning: SE14,...

This publication describes the aim and outcome of the constructions made to estimate deterioration/degradation of roads from the load of heavy traffic. The purpose was to study three constructions with three different wheel-loads (40 kN, 50 kN and...

Undersökning av mekanisk nedbrytning av obundna material vid tung trafik under byggnation...

In Sweden the rock qualities are based on mechanical analyses such as the Studded Tyre Test, Microdeval and Los Angeles Tests. One of the issues in this project is whether these tests are sufficient to determine the rock quality. The Heavy Vehicle...

Utveckling av expertsystem för bedömning av bergmaterialens mekaniska egenskaper:...

On behalf of the Swedish Transport Administration, Luleå University of Technology (LTU)/Envix North Ltd and the Swedish National Road and Transport Research Institute (VTI) developed the expert system for evaluation of rock materials' mechanical...

Expertsystem för bedömning av bergmaterialens mekaniska egenskaper

The purpose of this project was to develop an assessment system for crushed rock aggregates mechanical properties based on petrographic properties and use for constructions purposes. Decisive data parameters were identified from research papers and...

Jämförelse mellan Los Angeles-värde och nedbrytning från hjullast

Since 2004 the Swedish Road Administration has had requirements on unbound base layer concerning the resistance to fragmentation, the Los Angeles value. To study how degradation from traffic load is affected by resistance to fragmentation five...
