The Expressway Pavement Maintenance Project Management Research-a Case Of W Expressway

Since the last century eighty’s, China’s first expressway, highway traffic mileage has reached85000km. Due to the early technology and conditions, part of the expressway in the aspects of design and construction have some defects, coupled with China’s accession to the WTO after the rapid economic development, the car retains the quantity increases, accompanied by the increase of service life of highway, China’s annual about300000kilometer highway asphalt pavement need to be overhauled, so the study of highway pavement overhaul project management it is particularly important. In addition, our country highway mileage in increasing, construction job is very onerous, therefore, the highway pavement maintenance overhaul has become the main project construction. Expressway sustainable development is the key to how to manage highway rehabilitation project.This article on Expressway overhaul engineering project management process were discussed, with W Expressway overhaul engineering project management for reference, on Expressway overhaul engineering project management system in quality management, schedule management and safety management are analyzed and studied. Combined with the W freeway design scheme of the project quality control, schedule control and safety protection of free control puts forward the concrete measures and countermeasures. The main contents are as follows:(1)Combined with the overhaul engineering characteristics, the project feasibility study, project approving, survey and design, bidding, construction, supervision, acceptance, and acceptance of the completed completion audit, various elements of management concept analysis and overview.(2)Analysis of overhaul engineering design work characteristics, as well as the work in the project management the particularity and the importance, emphasizing the expressway overhaul engineering design work is a dynamic design process, design overhaul to determine the service life of the existing road conditions, investigation and evaluation of pavement structure combination, choice is the design key point and the difficulty, and puts forward the design should be fully considered in the operation characteristics of highway repair, ensure’ half site opened half site construction " ensure the smooth demand and construction organization requirements.(3)Combined with W Expressway overhaul engineering management practice, analysis the construction units in the whole quality management system in the role and the overhaul engineering quality management difficulties and characteristics, such as primary reinforcement, crack treatment, joint processing, mix and transport and so on; use of causality diagram, through analysis, strategy making, strategy implementation, the effect inspection steps to the cold regeneration following surface evenness quality special problem gives solve; elaborated the SMA mastic asphalt Expressway Pavement Repair Technology in the w application, to break the structure due to high construction difficulty and cannot be applied to the maintenance of the inherent thinking.(4)Combined with W Expressway overhaul engineering progress control measures, illustrates the importance of project progress control, briefly introduces the progress of the project planning process, such as Gantt chart method, and the expressway overhaul engineering schedule control factors and countermeasures are analyzed, from which to reduce costs, improve quality, shorten the construction period, works for the task the smooth completion of security.(5)Combined with W Expressway overhaul engineering safety free measures, emphasizing the maintenance construction safety free coequal and as important as quality, achieve quality and ensure the smooth construction and ensure the smooth simultaneously, if the conflict, priority should be given to ensure the smooth, firm establish service consciousness, past Secretary multiplied and social interests in the first place. And put forward Expressway overhaul engineering of two kinds of traffic organization, as well as in uninterrupted traffic construction situation of traffic management, safety free measures, safety measures and accident emergency measures.Through the theory analysis, measures and application of engineering as an example to discuss, system of expressway project management standards, norms, strict measures, for the subsequent expressway pavement repair project management practice to provide the necessary theoretical basis and reference data.
