PAVEMENT RESPONSE AND EQUIVALENCES FOR VARIOUS TRUCK AXLE AND TIRE CONFIGURATIONS

Many changes in allowable loading and operating procedure for trucks are under consideration in Washington and other states. For example, daul tires and single "flotation" tires for heavy truck loads may have varying damaging effects on pavements. Furthermore, at least for asphalt pavements, time of year and vehicle speed may also influence the analysis for special heavy load permits. This paper is a brief attempt to consider some of these variables on a relative basis. This paper is intended to be a limited approach to answer several pertinent questions from a theoretical study based on hypothetical pavements and loads and also on reasonable material characteristics and pavement behavior from previous research. The computer program was used to compute structural behavior. Maximum allowable numbers of load applications were determined by use of known fatigue and failure design curves. The results are a series of relationships based on pavement life that can be used to determine any number of equivalences. These equivalences can be used to compare the relative destructive effects of various sizes of single and dual tires, axle loads, pavement thicknesses, speeds, and temperatures. The general nature of these relationships provides a wide range of conditions for comparison. Within reason, interpolation is valid. One must keep firmly in mind, however, that these relationships are for assumed conditions (although reasonable) and do not represent actual pavements. /Author/
