Gross axle weight rating : ウィキペディア英語版 | Gross axle weight rating The gross axle weight rating (GAWR) is the maximum distributed weight that may be supported by an axle of a road vehicle. Typically, GAWR is followed by either the letters FR or RR, which indicate front or rear axles respectively. ==Importance== Road damage rises steeply with axle weight, and is estimated "as a rule of thumb... for reasonably strong pavement surfaces" to be proportional to the fourth power of the axle weight. This means that doubling the axle weight will increase road damage (2x2x2x2)=16 times.〔(【引用サイトリンク】title=Equivalent Single Axle Load )〕〔(【引用サイトリンク】title=Truck Weights and Highways )〕 For this reason trucks with a high axle weight are heavily taxed in most countries. Examples of GAWR on common axles.
