Review of Economical Efficiency of ECOPHALT Pavement ; The concept of L.C.C (Life Cycle Cost) is positively adopted Comparison with ASPHALT mixture's price (per ton) Conventional close grade #78 : 35,500won New Technology Ecophalt : 65,000won Economic price reduction ratio : 80% (per 100§³)   Conventional pavement #78 pavement (material cost + construction cost) 8800,000 won-110,000 won construction cost Soundproofing walll (2MSPAN) per M (based on 4 lane road) 1,300,000 won environment cost slipping prevention per a ( 50% of pavement) 3,500,000 won safty cost total 5,600,000- 5,900,000 won environmental safty new technology of ECOPHAT ECOPHALT (material cost + construction cost) 1,100,000 won saves 80-81% of the initial cost(4,500,000-4,800,000 won) cost-cutting of noise insulation wall and slipping prevention pavement(environment cost+safety cost) Comparison with Conventional pavement zone : Cost reduction of 50% and above/after 4 years (The concept of L.C.C)   -life cycle: ordinary pavement- 4years -ECOPHALT-10 years Comparison in respect to Environmental Pollution (50% reduction)   -Conventional pavement: Construction of noise insulation wall required -ECOPHALT pavement : Soundproofing wall not required or only lower wall required (47%-54% reduction) Prevention of Traffic Accident & Reduction in Cost caused by Traffic Congestion   -Conventional Pavement : Measures are required to prevent traffic accidents occurring on slippery rainy road. -ECOPHALT : Pleasant and safe driving conditions are maintained (Increase in resistance to slipping : Cost reduction : 23%-25%) Road designed to prevent life loss/ Cost of life loss can not compared -ECOPHALT : Cost of traffic congestion caused by rainy road and fuel consumption (per car) An average of 6000-7000 won (compiled by Britain) (In the case of a road with 10,000 cars running a day) : In case of Seoul 1 million cars a day/2*7000 won=3.5 billion won worth of cost
