R&D ADOPTION OF INNOVATIONS AND TECHNOLOGIES FOR SUSTAINABLE ROAD INFRASTRUCTURE PRESENTED BY : E-mail: eyothom@yahoo.com Website: www.eyotb.com Mobile: +234-803-370-5986 1

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. 2

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. 4

FERMA ROAD TECHNOLOGY 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 of the road and rolling in of 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. 16

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. 20

ASPHALT RUBBER 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. 26

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 of concrete or using bamboo sticks as reinforcement bars in concrete.  The present curriculum of engineering degrees in Nigerian Universities needs a radical change. 29
