Embodiment

[0044] Xi'an City Ring Expressway, 80 kilometers in length, is fully enclosed and fully interchanged. It is designed according to the two-way six-lane standard, and the design speed of the entire line is 120 kilometers per hour. It is the main hub of the modern highway network in Shaanxi Province. The Xi'an City Ring Expressway is divided into two sections, the south and the north. Among them, the north section of the city belt is 34 kilometers long. It starts from the Fangjiacun Interchange and ends at the Maoerliu Interchange. The subgrade width of this section is 35 meters, and the road surface is asphalt concrete pavement. Channelized traffic is implemented, and vehicles are strictly divided into lanes.

[0045] Since it was completed and opened to traffic, due to the increase in traffic volume and the gradual increase in heavy-axle-loaded vehicles, coupled with the continuous high temperature in summer, there have been obvious cracks and ruts in the wheel tracks of some se...

Abstract

The invention discloses a bituminous pavement preventive maintenance method based on swinging lane markings, which overcomes the shortcomings including long construction period and high construction cost of the existing roadway maintenance methods. The method is carried out from a traffic engineering perspective, swings construction partition positions of traffic lane markings at adequate time and amount, realizes guiding of re-distribution of driving wheel marks of vehicles, and further achieves the aims of improving road surface effective utilization, delaying development of road surface diseases and prolonging the service life of the road surface. The bituminous pavement preventive maintenance method based on swinging lane markings has the advantages of being low in cost, fast in construction speed, energy-conservation and environment-protection.

Description

technical field [0001] The invention relates to a method for preventive maintenance of asphalt pavement, in particular to a method for preventive maintenance of asphalt pavement based on swinging lane markings. The method is suitable for preventive maintenance of asphalt pavement of expressways. Background technique [0002] Asphalt pavement has the advantages of good driving comfort, short construction period, easy maintenance and repair, and is suitable for phased construction, so it is widely used. At present, the vast majority of highways in my country use asphalt pavement, and the proportion reaches more than 90%. However, under the combined effect of vehicle load and environmental factors on asphalt pavement, the following diseases are prone to occur: rutting, cracks, potholes and other diseases. These diseases will reduce the performance and service level of the pavement, and shorten the service life of the pavement. [0003] In order to ensure the safe, orderly and...
