The investigations has shown that, apart from conserving precious construction materials and reducing the maintenance requirements of the previously unpaved roads, a significantly better level of service was achieved with a concomitant reduction in road user costs. Although the roads have required intermittent maintenance during their lives, they have clearly shown that current materials standards may be too conservative for affordable low volume roads.
