Low volume roads (Periods 1995 to 2000 and 2000 to 2003) |
Two LVR options investigated: Surface treatment of existing gravel road near Bultfontein. Imported natural gravel base with surface seal at Lamberts Bay. Testing included HVS and comprehensive laboratory testing.
|
Assess structural bearing capacity of light pavement structures compared to estimated bearing capacity in TRH4. Assess appropriateness of HVS testing on these pavements - structural vs. functional performance. Establish minimum strength requirements for marginal base layer materials. HVS tests 385A4 to 393A4; 419A5 and 420A5 |
Large difference between structural performance under HVS and functional performance under real-life conditions. Structural capacity of LVR design seems adequate from early results. |
