3. MAP SOURCE: COOPERATION CAMEROON – UNION EUROPEENNE
CAMEROON being “Africa in
miniature”, with its vegetation ranging
from dense Equatorial Rainforest in
the Grand South (where the Rainy
season lasts for about 9 months), to
the semi-arid Sahara Desert
landscape in the Grand North (where
the Rainy season lasts for only 3
33
the Rainy season lasts for only 3
months), passing through the rugged
Savannah Plateaus in the Mid-West,
about 95 % of all soil types in Africa
can be found here in CAMEROON.
CAMEROON: One of the most
Peaceful Countries
in Africa.

5. WHY DO EARTH ROADS DETERIORATE ?WHY DO EARTH ROADS DETERIORATE ?
EXCESSIVE RAINFALL MAKES THE MOISTURE CONTENT OF THE
SOIL TOO SATURATED FOR OPTIMUM COMPACTION.
SCARCITY OF GOOD QUALITY LATERITE FOR THE WEARING
COURSE.
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.

6. WHY DO EARTH ROADS DETERIORATE ?WHY DO EARTH ROADS DETERIORATE ?
ABUSIVE OVERLOADING (NO WEIGHING STATIONS INSTALLED ON
EARTH ROADS).
SURFACE RUNOFF WATER CROSSING THE ROAD.
POOR PERFORMANCE OF SOME ROAD MAINTENANCE
CONTRACTORS.
DIFFICULT CONDITIONS IMPOSED BY THE VILLAGERS BEFORE
EXTRACTION AT THE BORROW PIT.

15. LATERITE IS NOT A RENEWABLE COMMODITY.
ITS DEPLETION DESTROYS THE ENVIRONMENT.
DURING THE DRY SEASON:
MANY HEALTH HAZARDS OF DUSTY GRAVEL ROADS AND
REDUCED VISIBILITY ARE A MAJOR ROAD SAFETY CONCERN.
DURING THE RAINY SEASON:
CRITICAL “BAD SPOTS” ON EARTH ROADS ARE A ROADCRITICAL “BAD SPOTS” ON EARTH ROADS ARE A ROAD
SAFETY NUISSANCE TO TRAVELLERS WHO OFTEN SPEND THE
NIGHT THERE AND ARE HARASSED BY 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.

19. THE WAY FORWARDTHE WAY FORWARD
USING COLD ASPHALT (e.g. CARBONCOR) AT
LARGE SCALE CAN BE A BREAK-THROUGH IN
DEVELOPING ROAD INFRASTRUCTURE IN AFRICA.DEVELOPING ROAD INFRASTRUCTURE IN AFRICA.
THIS IS A WORKABLE STRATEGY
&
A POSITIVE VISION FOR THE FUTURE OF AFRICA
