LATERAL PLACEMENT OF TRUCK WHEELS WITHIN HIGHWAY LANES

In recognition of the need for representative statistical data on the lateral placement of truck wheels within highway lanes, a video camera was used in a following vehicle to record rear-view images of trucks operating on multilane highways in Texas. Analysis of the data set that resulted from evaluating these images produced four frequency distributions of lateral wheel positions that are definitive for two different truck types and for two roadway alignment conditions. A single frequency distribution could not be used to describe the observed placement patterns with acceptable accuracy. To illustrate the effects of laterally distributed traffic loading on the design thickness of rigid pavements, computations were made for 1, 10, and 20 million repetitions of loads concentrated at the pavement edge and for the same number of loads distributed laterally in accordance with a representative frequency distribution. A thickness reduction of about 15 percent could be realized if the lateral distribution of loads were incorporated into the design process.
