Theory, Method And Application Of Highway Construction Policy Based On Life-Cycle Benefit

Besides the fast development and glorious achievements in the highwayconstruction of China, there are still some problems in construction quality andenvironment protect as well as structural durability etc. The theoretical andmethodological policy systems of the highway construction based on the optimizedlife-cycle benefit have been studied in three aspects of highway layout policies,construction policies and maintenance policies in this dissertationThe existed highway construction policy of China is reviewed. The author cameto a conclusion that there is an urgent need in improving our highway constructionpolicy system. The important role of the public goods theory, public managementtheory in management and economics theories is clarified, and their theoreticalrelationship and methodological guide on the constituting of highway policies areemphasized.The basic theory of highway construction policy is proposed, including itspracticability from policy making environment, policy overall design, policy system,policy technical means and fundamental principles. The theoretical framework of theconstituting of highway construction policy is generally set up, based on life-cycleconsideration. The traditional highway construction cost analysis and LCCA arecompared with each other. In the meanwhile, the general plans and basic techniqueeconomic principles of highway construction policy is stated, and the basic methodsystem of highway construction policy-making based on LCCA is finally established.The intension of the system proposed in this dissertation is further enriched inthe layout policies, construction policies, and management and maintenance policies.It is strengthened that the layout policy based on the life-cycle cost analysis requiredthe major policies orientation of land consolidation and utilization. Policy safeguardmechanisms required in the highway construction process are concluded here fromregulatory regime, quality control and environmental protection. Based on circulareconomy theory, the economics foundation of construction policy-making is established preliminarily, emphasizing the ecological design concept, the humanitydesign concept, the durability performance design concept, and such key policyconcepts, thereby establishing comparatively suitable theory and method systems inthe highway construction phase based on the life-cycle design strategy. With thesummarization of current management and maintenance stations and future demandof management and maintenance work in China, the author states clearly what isneeded to be improved. Then the technical gist of life-cycle management andmaintenance and raised proposals about policy-making of life-cycle highwaymanagement and maintenance is explanted.
