Detailed Design and Construction of the Upgrading National Road No. 48 Project

I have an honor to express my very deep and endless gratitude to my dear parents who have not just brought me up every well but also continuously love, encourage, support, advice, and care for me always. Without both, I would not have been as I am today.
I would like to express my truly sincere appreciation to my generous supervisor, Dr. Yin Hor, for his valuable time, useful instruction, support, encouragement, and helpful guidance.
I am grateful to all lecturers and professors at National Polytechnic Institute of Cambodia (NPIC) for providing me the knowledge, advice, discussion, and encouragement in order to successfully obtain my master’s degree.
My grateful thanks to all official staff working in the Graduate School office, who inform the updated information to international students, for their helpfulness and kind cooperation.
I also would like to show my appreciation to all my brothers, sisters, and friends for their support and encouragement to make me work through successfully.
Finally, I thank my beloved wife for her remarkable patience, continuous encouragement, unrelenting support, and warming care. She is truly my friend and my wife; I am so blessed from the Lord to marry her.
