Study On Preventive Maintenance Technology Of Asph Alt Pavement Of S211 Beitai Line

In recent years,traffic has increased year by year,traffic pressure is increasing.Asphalt pavement usually in the early construction will be a slight disease,if not timely measures will bring damage to the structure of the road,is not conducive to the late road maintenance work needs.Therefore,in view of this situation,how to carry out reasonable and timely preventive measures on the existing road,in the asphalt pavement before the structural damage to the road before the corresponding preventive maintenance measures to ensure good road performance,to extend the road Of the service life,to reduce the late asphalt pavement maintenance costs of great significance.The traditional road maintenance is carried out when the road surface damage is serious,even the road structure has also been destroyed.If there is a serious disease before the timely detection of early pavement pavement are small,by regular inspection of road conditions,and take appropriate preventive maintenance measures to dispose of them,so as to shorten the maintenance period,to reduce unnecessary waste of money.Based on the investigation and analysis of the existing types of disease and the causes of the existing diseases on the Sinkai pavement of S211,this paper analyzes the current situation of the existing diseases of the asphalt pavement based on the development of the asphalt pavement preventive maintenance technology.According to the indicators such as road damage,road running quality,pavement structure strength index The paper analyzes the technical characteristics,construction characteristics,applicability and different technical requirements of the preventive maintenance measures at home and abroad,and introduces the raw material requirements of the microfilm,fog seal and other conservation measures,Construction technology,construction points.And in accordance with the project,taking into account the technical factors put forward the application of potting,micro-surface,fog seal and other pre-curing technical measures in the S211 line maintenance project,and relying on the project S211 North Taiyuan preventive maintenance effect of the final show that the pre-maintenance Effectively inhibited the development of pavement disease,played a timely protection of the role of pavement structure,and in improving the road performance at the same time,reducing the late maintenance costs,resulting in significant social benefits.
