WHY DO EARTH ROADS DETERIORATE ?WHY DO EARTH ROADS DETERIORATE ?

� EXCESSIVE RAINFALL MAKES THE MOISTURE CONTENT OF THESOIL TOO SATURATED FOR OPTIMUM COMPACTION.

� INCREASING SCARCITY OF GOOD QUALITY LATERITE FOR THEWEARING COURSE.

� DIFFICULT CONDITIONS IMPOSED BY THE VILLAGERS BEFOREEXTRACTION OF LATERITE AT THE BORROW PIT.EXTRACTION OF LATERITE AT THE BORROW PIT.

� POOR ATTITUDE OF THE POPULATION AND ROAD USERS TOWARDSPROPER ROAD USAGE (E.G. DIGGING, OBSTRUCTION OF DITCHESFOR PATH-WAYS, ETC.).

� NON-RESPECT OF RAIN-GATES AND CONTINUOUS CIRCULATIONDURING RAINS BY TRUCK DRIVERS.

WHY DO EARTH ROADS DETERIORATE ?WHY DO EARTH ROADS DETERIORATE ?

� ABUSIVE OVERLOADING (NO WEIGHING STATIONS INSTALLED ONEARTH ROADS).

� POOR PERFORMANCE OF SOME ROAD MAINTENANCECONTRACTORS (e.g. LACK OF FUNDS, EQUIPMENT).

� INADEQUATE MONITORING & EVALUATION DURING THE EXECUTION� INADEQUATE MONITORING & EVALUATION DURING THE EXECUTIONOF WORKS (e.g. INSUFFICIENT LOGISTICS, PERSONNEL).

� SURFACE RUNOFF WATER CROSSING THE ROAD.

� LACK OF A SPOT MAINTENANCE POLICY [A STITCH IN TIME SAVESNINE].

� DURING THE DRY SEASON:� MANY HEALTH HAZARDS OF DUSTY GRAVEL ROADS,

(EX. RESPIRATORY INFECTIONS).� REDUCED VISIBILITY IS A FREQUENT CAUSE OF ACCIDENTS.

� DURING THE RAINY SEASON:� CRITICAL “BAD SPOTS” ON EARTH ROADS ARE A ROAD

ROAD SAFETY CONCERNS FOR EARTH ROADSROAD SAFETY CONCERNS FOR EARTH ROADS

� CRITICAL “BAD SPOTS” ON EARTH ROADS ARE A ROADSAFETY NUISSANCE TO TRAVELLERS WHO OFTEN SPEND THENIGHT THERE AND ARE EXPOSED TO THIEVES.

� TRAVEL TIME IS GREATLY INCREASED.� VERY HIGH IMPOSED TRANSPORT FARES.� INFLATED PRICES FOR HINTERLAND GOODS.� DIFFICULTIES IN EVACUATING PATIENTS.� OVER-LOADING OF TRANSPORT VEHICLES.� HIGH VEHICLE OPERATING COSTS.
