    (b) Inadequate wearing course: If the wearing course is of inadequate thickness or if it is totally absent the sub-base or base courses are exposed to the damaging effects of the climatic agencies and the traffic. (c) Lack of lateral confinement: If lateral confinement is not provided for granular sub-base or base courses the action of traffic causes the materials of these courses to spread out.
