Study On The Key Measures And Technology Of Improving The Pothole Repairing Quality Of Asphalt Pavement

By the investigation on the Anqiu arterial highway asphalt pavement deseases that at present Anqiu arterial highway pothole disease more serious, and further appeared potholes a greater probability of. Annual custody institutions put the great manpower, material resources into pothole disease treatment, but still can not solve the problem of this group of diseases. Therefore, how to improve the quality of asphalt pavement pothole repair becomes Anqiu Highway Bureau facing one of the most important maintenance task. The main research work covers the following aspects:(1) By the investigation on the Anqiu arterial highway pothole desease, summaried on the typical pothole damage type of present Anqiu arterial highway, made a comprehensive, detailed classification.And then analyzed the cause of the pothole distresses and expansion.(2) By the investigation on damage of the Anqiu arterial highway repaired potholes, summaried on the typical repaired pothole damage type of present Anqiu arterial highway. And then analyzed the damage cause of the several forms of damage one by one, Through analysis of the impact factors of repairing pothole quality of Anqiu arterial highway asphalt pavement were determined.(3) By the verification analysis of factors affecting the construction quality of pothole repair of asphalt pavement one by one, the key influence factors of construction quality of Anqiu Highway Bureau were determined at present. And then made countermeasures one by one, and further improve and refine construction technology of the pothole repair of asphalt pavement. In addition to pothole repair of asphalt pavement and new construction is not the same, but there is no specific inspection and evaluation standards of maintenance engineering, construction quality control inspection standards of the pothole repair of asphalt pavement of the Anqiu Highway Bureau was determined.
