Abstract

The embodiment of the invention discloses a pavement performance prediction and maintenance method and device based on maintenance history correction. The method is based on road conditions, traffic volume data and maintenance history data of a route over the years, and adopts a modeling idea of "model grouping, year-by-year accumulation and elimination of maintenance history influences, data update dynamic correction" to finally obtain a pavement performance decay model that is based on untreated actual road condition data over the years and considers traffic volume cumulative axle-load influences. The model established by the method not only can be used to accurately predict the natural attenuation index of road conditions of a pavement in future years, but also can be used to assist incalculating preventive maintenance benefits and judging the best maintenance time in the aspects of pavement maintenance planning and decision-making, and meanwhile, when performing multi-year planning, more scientific and reasonable maintenance schemes and plans can be formulated based on accurately predicted road condition attenuation values, and the reasonable forecast of pavement maintenance funds can be achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of road surface maintenance, in particular to a method and device for predicting and maintaining road surface performance based on maintenance history correction. Background technique [0002] In the project-level pavement maintenance decision-making system, the core element it relies on is the establishment of the pavement performance model. Traditional methods for establishing pavement performance models mainly include deterministic and probabilistic models, among which the deterministic model is easy to use and more widely used. In the deterministic model, the traditional method mainly has the following deficiencies: 1) It does not reflect the impact of traffic volume and axle load on road attenuation. The traditional method establishes the relationship between the road condition index and the road age, which fails to reflect the attenuation of the road surface performance by th...
