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.
