The most commonly used equivalent load in the U.S. is the 18,000 lb (80 kN) equivalent single axle load (normally designated ESAL). At the time of its development (early 1960s at the AASHO Road Test ) it was much easier to use a single number to represent all traffic loading in the somewhat complicated empirical equations used for predicting ...

esal是轴载组成、轴载换算系数、交通量平均增长率和 轮迹横向分布系数 等的函数，这些参数本身是按一定的方法进行数据采集和统计分析的结果 。但由于这些统计参数都具有很大的随机性，导致其在检测和统计分析过程中必须存在一定的误差 。

The equivalent load most commonly used in pavement design in the U.S. is the 18,000 lb (80 kN) equivalent single axle load (ESAL). This tool calculates the total number of ESALs that have or will traverse a pavement for the purposes of pavement analysis or design.

2024年5月16日 · An ESAL, or equivalent single axle load, represents the damage effect from a single pass of a standard axle load. The damage effect of any vehicle can be expressed in terms of ESALs – the specific number of passes of a standard axle that would cause the equivalent damage as a single pass of the vehicle.

ESAL is the acronym for equivalent single axle load. ESAL is a concept developed from data collected at the American Association of State Highway Officials (AASHO) Road Test to

2025年2月23日 · In pavement engineering, determining the Equivalent Single Axle Load (ESAL) is a crucial step in designing a durable and efficient roadway. ESAL simplifies the complexity of mixed traffic loading by converting it into a single representative value, allowing engineers to assess the cumulative impact of various vehicle types on pavement performance.
