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. Assessment of pavement damage was accomplished by determining average EALs associated with each class of trucks. Also, truck traffic patterns on Arkansas highways and percent of equivalent axle loads (EALs) generated by each class of trucks 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. 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.
