Abstract:

Iowa's county road system includes several thousands of miles of paved roads which

consist of portland cement concrete (PCC) surfaces, asphalt cement concrete (ACC) surfaces,

and combinations of thin surface treatments such as seal coats and slurries. These pavements are

relatively thin pavements when compared to the state road system and therefore are more

susceptible to damage from heavy loads for which they were not designed. As the size of the

average farm in Iowa has increased, so have the size and weights of implements of husbandry.

These implements typically have fewer axles than a truck hauling the same weight would be

required to have; in other words, some farm implements have significantly higher axle weights

than would be legal for semi-trailers. Since stresses induced in pavements are related to a

vehicle's axle weight, concerns have been raised among county and state engineers regarding the

possible damage to roadway surfaces that could result from some of these large implements of

husbandry.
