INTRODUCTION

• Research begins where Why and How are asked.
• Questioning conventional wisdom is the origin of

research.

• Innovation is the answered question to a

successful research while adoption is the application of innovation.

• Sustainability is the application of innovations to

meet the needs of the present without compromising the ability of future generations to meet their own needs.

FERMA ROAD PRODUCTS & MATERIALS

ROAD MAT

• FERMA Road mat is a prefabricated road maintenance

product on kraft paper onto which bitumen mixed with crumb rubber holds a compacted aggregate of various sizes depending on the intended usage.

• Sheet size: 1.0m x 0.75m.

Aggregate sizes : 2.75mm – 19mm.

• Weight 4kg and 25kg.
• Local cost N900/mat as against the imported price of

N3000/mat.

• The product is highly flexible and totally waterproof.
• Road mat is used for Road Patching, Crack Sealing, Traffic

Calming and Safety Devices.

FERMA ROAD PRODUCTS & MATERIALS Cont’d

COLD ASPHALT

 FERMA Cold Asphalt;

100 % locally available materials.

 Unlike HMA concentrate

produces superior bonding strength resulting in a strong, trafficable, long lasting and skid resistance waterproof surface.

 Satisfies binder and

wearing course Marshal mix design specification in addition to boil test.

 FERMA Cold Asphalt

used in almost all states including highly trafficked Benin- Shagamu Road and Third Mainland Bridge in Lagos.

 The report has been very

promising.

FERMA BITUMEN EMULSION

 Bitumen emulsion;

bitumen, water, and an emulsifying agent.

• Bitumen / Kerosene =

Volatile Organic Compound (VOC) is a popular solvent used in the preparation of cutback bitumen for road works.

 Bitumen-kerosene

(cutback) mixture more harmful than carbon dioxide (CO2) which is greenhouse gases that causes global warming. USAGE

 Tack Coat, Priming,

Surface Dressing, Slurry Seal,Cold asphalt etc.

 Identified and well

labelled for use.

• Quality Control Tests.

Distillation, Viscosity,

• Particle charge and float

test

11

BITUMEN EMULSION CONT’D

ADVANTAGES

 Reduces carbon dioxide

emission by almost 2/3 while reducing the production of photo chemical smog generating VOCs emission.

 It saves energy since it does

not require heating or the use of a petroleum solvent.

 Reduces atmospheric

pollution as heating is not involved

 Road maintenance works

easier in remote areas and cold weather where heating might be cumbersome.

 Asphalt emulsions can coat

damp aggregate surfaces thereby reducing the fuel requirement for heating and drying aggregates.

 Improved workers health

and safety.

 Non toxic.  24 hours to fully cure.  Cutbacks 72 hours to fully

cure.

PAVEMENT RESURFACING BY FUMIGATION

• Pavement Resurfacing by Fumigation - a

jargon by the author, is the application of solvent to a film of excess bitumen on the surface

• f

the road and rolling in

• f

aggregate size of 3/8 to dust leaving a non skidding surface.

• First used to control bleeding on Km3+00-

km7+00 on Damaturu-Maiduguri Road, North East, Nigeria.

ASPHALT RECYCLING

 Reuse of material that have served its first

intended purpose.

 Types:

Cold In-Place, Hot In-Place, Central Plant, Cold planning. Advantages:

 Saving of about 40-80% in the use pavement

material.

 Reuse and conservation of bitumen and

aggregate.

 Energy conservation.  Shorter construction period.  Reduction in user delays during construction.

Monumental Waste of 100% Recyclable Resource

SLOPE PROTECTION USING GABION MATTRESSES AND GEOTEXTILE

 Traditionally slope

protection ;top soiling, grassing and stone pitching etc.

 Reinstatement of failed

slope; no work space for compaction.

 Quality and compaction of

the reinstated material is not always ascertained. Advantages:

 Permeability, Reduces pore

water pressures behind the structure and allowing free drainage.

 Cost effective, aesthetically

pleasing and environmentally friendly. No heavy plant or machinery.



Rapidly constructed making it ideal for emergency works.

 The geotextile underlayer

allows for filtration to prevent loss of subsoil material as a result of drainage flow through the gabion.

Engineers and Chemist incorporate Rubber into Asphalt with the Following Benefits:

• Resistance to bleeding.
• Reduction in traffic noise.
• Reduction in mat thickness.
• Last longer, chemical in scrap tyre retards aging

and oxidation.

• Bitumen rubber could be used as crack sealant.

Conclusion

 We owe the Nigerian engineering community and the

general public a duty if we fail to commence the needed reform in the nation’s highway sector.

 There should be synergy between NUC or Individual

Universities and MDAs, Civil Engineering contractors and consultancy firms so as to replace the volume of theoretical or abstract subjects or topics as it is contained in the present engineering curriculum in Nigerian Universities.

28

Conclusion cont’d

 Professional lecturers in the Universities should be encouraged

to do their sabbatical in MDAs and companies so as to bridge the gap between theory and practice.

 Universities should discourage students embarking on research

that would forever remain an academic adventure on the University library shelves e.g. using periwinkle shelve as aggregate for production

• f

concrete

• r

using bamboo sticks as reinforcement bars in concrete.

 The present curriculum of engineering degrees in Nigerian

Universities needs a radical change.
