The Government of Vietnam has been constructing rural roads throughout Vietnam to provide year-round access to communes hitherto suffering from lack of this basic infrastructure facility. Almost all road links constructed under major rural transport programmes are constructed to gravel or stone macadam pavement standard. The experience has been that in many provinces, these pavements have deteriorated quickly due to the particularly aggressive environment in Vietnam. Gravel roads also cause environmental pollution due to dust in the dry season (especially near markets,
schools, hospitals, etc.) and create a burden for local people who are principally responsible for the maintenance.
Clay Brick pavement is one of the options being investigated as an appropriate alternative surfacing for rural roads.
