8. WHY DO EARTH ROADS DETERIORATE ?WHY DO EARTH ROADS DETERIORATE ?
EXCESSIVE RAINFALL MAKES THE MOISTURE CONTENT OF THE
SOIL TOO SATURATED FOR OPTIMUM COMPACTION.
INCREASING SCARCITY OF GOOD QUALITY LATERITE FOR THE
WEARING COURSE.
DIFFICULT CONDITIONS IMPOSED BY THE VILLAGERS BEFORE
EXTRACTION OF LATERITE AT THE BORROW PIT.EXTRACTION OF LATERITE AT THE BORROW PIT.
POOR ATTITUDE OF THE POPULATION AND ROAD USERS TOWARDS
PROPER ROAD USAGE (E.G. DIGGING, OBSTRUCTION OF DITCHES
FOR PATH-WAYS, ETC.).
NON-RESPECT OF RAIN-GATES AND CONTINUOUS CIRCULATION
DURING RAINS BY TRUCK DRIVERS.

9. WHY DO EARTH ROADS DETERIORATE ?WHY DO EARTH ROADS DETERIORATE ?
ABUSIVE OVERLOADING (NO WEIGHING STATIONS INSTALLED ON
EARTH ROADS).
POOR PERFORMANCE OF SOME ROAD MAINTENANCE
CONTRACTORS (e.g. LACK OF FUNDS, EQUIPMENT).
INADEQUATE MONITORING & EVALUATION DURING THE EXECUTIONINADEQUATE MONITORING & EVALUATION DURING THE EXECUTION
OF WORKS (e.g. INSUFFICIENT LOGISTICS, PERSONNEL).
SURFACE RUNOFF WATER CROSSING THE ROAD.
LACK OF A SPOT MAINTENANCE POLICY [A STITCH IN TIME SAVES

15. 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 ROAD
SAFETY NUISSANCE TO TRAVELLERS WHO OFTEN SPEND THE
NIGHT 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.
