Abstract: Regarding vehicle and road as one system , rational maxim axis load is put for ward definitely in the paper. Vehicle profit and road expense are calculated using zero-value profit method and cost incremental method. Axis load is converted according to rut evaluation system, more important, equivalent single axis load (ESAL) is introduced in calculating road expense. Consequently, ideal model of rational maxim axis load is established, which makes the
problem of insufficient data or inaccurate statistics abstained, moreover the same time, the calculating procedure is predigested greatly.

Key words: vehicle, road, axis load, vehicle-road system

摘要: 本文采用利润零值法和费用增量法对路面费用和车辆费用进行了计算,在以车辙作为
路面破坏衡量指标和轴载换算的条件下,建立了合理极限轴载(RMAL)的增量型优化模型,路
面费用的计算中引人了当量轴载次数(ESAL)值作为评价指数.采用这一理想合理轴载模型,
避免了因数据资料不足或统计不准确等带来的弊端,通过求优模型使得车辆和路面费用计算分
析大大简化.
