Latex Modified Concrete(LMC) has been widely used on highway bridges over the past 35years around the world since it is more resistant to the intrusion of chloride ions, has higher tensile, compressive, and flexural strength, and has greater freeze-thaw resistance. However, in Korea it has not been introduced to fields due to higher initial construction cost for its overlay than conventional pavement materials. Due to durable characteristics it should be noted that the LMC may be cost-effective than conventional pavement technique such as asphalt pavement technique considering life-cycle cost(LCC) concept. The objective of this study is intended to suggest a practical LCC analysis model for pavement projects and to demonstrate relative cost-effectiveness of LMC overlays comparing with conventional pavement techniques. It may be stated that the procedure proposed in this study can be utilized for optimal decision of cost-effective pavement design.
