ADDIS ABABA UNIVERSITY SCHOOL OF GRADUATE STUDIES INSTITUTE OF TECHNOLOGY COMPARATIVE LABORATORY STUDY ON FLY ASH AND WOOD ASH AS FILLER MATERIAL IN HOT MIX ASPHALT A Thesis submitted to the School of Graduate Studies of Addis Ababa University in partial fulfillment of the requirements for the Degree of MASTERS OF SCIENCE IN CIVIL ENGINEERING (ROAD AND TRANSPORT ENGINEERING) Advisor: Bikila Teklu (Ph.D) Co-Advisor: Asres Simeneh (MSc.) BY DAGMAY LEMMA BATU JUNE, 2016 ADDIS ABABA UNIVERSITY SCHOOL OF GRADUATE STUDIES INSTITUTE OF TECHNOLOGY COMPARATIVE LABORATORY STUDY ON FLY ASH and WOOD ASH AS FILLER MATERIAL IN HOT MIX ASPHALT BY DAGMAY LEMMA BATU Approved by the Board of Examiners Chairman Advisor Internal Examiner External Examiner Page | I 2016 Comparative laboratory study on Fly Ash and Wood Ash as a filler material in HMA Declaration This thesis is my original work and has not been presented for a degree in any other university, and that all sources of material used for the thesis have been duly acknowledged. Candidate’s name_________________________ Signature___________________ Date of submission: June, 2016 Addis Ababa Institute of Technology Page II 2016 Comparative laboratory study on Fly Ash and Wood Ash as a filler material in HMA ACKNOWLEDGEMENTS I would like to express my sincere gratitude from the bottom of my heart to my Advisor Bikila Teklu (Ph.D) and my Co-Advisor Asires Simeneh (MSc.) for their invaluable guidance throughout the thesis work and their voluntariness to support. I wish to express my gratitude to The Federal Democratic Republic of Ethiopia, Ethiopian Roads Authority (ERA) for giving me financial support to study this post graduate program. My Thanks also goes to the Addis Ababa City Roads Authority (AACRA) staff members who were supportive in collecting of aggregates and bitumen sample which is an input for my thesis work. The last but not the least I truly like to thank CORE Consulting Engineers Company which helped me to conduct the laboratory tests.
