Thirteen short surfacing/pavement trial sections were constructed on seven different low volume roads under SEACAP 17 in North-western Lao PDR. These roads were notable for their low traffic volumes (roads carrying 43-210 vehicles per day excluding motorbikes) and low axle loads (motorbikes, tok tok and small number of cars and light trucks less than 5t). This presentation contrasts and compares the different techniques and materials used in order to see if certain engineered pavements can provide more economical alternatives to re-gravelling.
