PAVEMENT DAMAGE ATTRIBUTABLE TO FOUR AXLE SINGLE UNIT TRUCKS

The objective of the study was to investigate and define the types of pavement damage which may be attributed to four axle single unit trucks and identify and define applicable terms and uses of the truck. Assesment of pavement damage was accomplished by determining average equivalent axle loads (EALs) associated with each class of truck. Also, truck traffic patterns on Arkansas highways and percent of (EALs) generated by each class of truck on rural arterials were determined. A test plate was developed which measured the resultant tire forces produced by the four axle single unit truck during tight turns. A national survey of state highway departments, weight and permit divisions and enforcement divisions was conducted. The survey asked for information concerning the usage and restrictions associated with four axle single unit trucks. Truck and lift axle manufacturers were surveyed for information on the manufacture and sale of lift axles. Recommendations were made concerning four axle single unit trucks which could reduce the EALs associated with these trucks by a factor of two to three. These recommendations would impose a minimal economic hardship on the truck owners and operators.
