Local Road Management Manual 74 Table 3.4 Typical Gravel Pavement Distresses Scouring These defects are locally termed as water cuts. These are scouring of water onto the pavement that is longitudinal, transverse or diagonal to the road way. This may be caused by the excessive flow of surface water due to blocked or insufficient drainage; due to eroded surface material; or inappropriate cross slope or grades. These may be repaired by clearing clogged drainage; providing diversionary drainage; appropriate cross slope; or replace surface materials with better properties. Shoving / The condition of the Presence of pavement that exhibits Mud mud-like characteristics. The pavement material shows highly plastic consistency causing excessive surface deformation or slippery mud conditions. This may be due to the plastic deformation of the subgrade; excess ponded surface water; heavy axle loads; shallow water table; excessive fine materials or inappropriate cross slope. These may be repaired by installing the required pavement thickness; providing good surface and side drainage; laying well graded and compacted materials; or providing the correct cross slope.
