Road damage due to heavy vehicles : Introducing 74-ton trucks on the road system (English)
Abstract [sv]

Näringslivet efterfrågar ett införande av 74 tons lastbilar på det statliga vägnätet. Det finns ett

flertal fördelar med att höja maximala bruttovikten från nuvarande 64 till 74 ton. Däremot är

höga bruttovikter direkt kopplade till bärighetsrelaterade skador. Syftet med denna studie är

att ligga till grund för vidare arbete av Trafikverket. Detta för att uppnå bättre kontroll på hela

det statliga vägnätet och den tunga trafikens inverkan. Studien har utgått från observationer i

PMSv3, ett webbaserat system med grafiska tvärprofiler baserade på vägytemätning samt

information om det statliga belagda vägnätet. Observationerna innefattar mönsteridentifiering

av återkommande tvärprofilstyper tillskrivna skador av den tunga trafiken. Resultatet av

tvärprofilstyperna har sedan analyserats och beskrivits som representativa spårtyper för det

statliga vägnätet. Slutsatsen är att det finns indikation på mönster av spårtyper. Utifrån

observationerna i PMSv3 har spårtyperna formulerats som hypoteser för vidare forskning.

Abstract [en]

The wood industry asks for an imposition of 74-ton trucks on the national road system. There

are several advantages of increasing the maximum gross weight from 64 to 74 tons. On the

other hand, high gross weights are directly connected to structural road damage. The purpose

of this study is to serve as foundation for further research by the Swedish transport

administration. The ulterior goal is to reach better control on the national road system. The

basis of the study is a web-based system - PMSv3, which contain road information and

transverse road profiles. The observations in PMSv3 have led to rut-types ascribed due to

heavy gross weights. The conclusion is that rut-patterns indications exist. Based on the

observations in PMSv3, the rut-types have been formulated as hypothesis for further research.
