Abstract:
THE INVESTIGATION INDICATED THAT, IN GENERAL, THE FREQUENCY OF HEAVY AXLES ON ROADS CARRYING 1,000 OR MORE TRUCKS DAILY IS ROUGHLY BETWEEN TWO AND SIX TIMES THE FREQUENCY ON THE LIGHTLY TRAVELED PORTIONS AND THAT THE VARIATION IN THE FREQUENCY IS IN DIRECT PROPORTION TO THE AVERAGE DAILY TRUCK TRAFFIC. THE HIGHWAY PLANNING SURVEYS HAVE GATHERED MUCH DATA CONCERNING THE COMPOSITION OF TRAFFIC IN THE VARIOUS STATES. USING THIS INFORMATION, AN INVESTIGATION WAS MADE TO DETERMINE VARIATIONS IN THE FREQUENCY OF HEAVY AXLES ON THE MAIN RURAL HIGHWAYS OF THE COUNTRY IN COMPARISON WITH THE AVERAGE DENSITY OF TRUCK TRAFFIC. IT FURTHER INDICATED THAT THERE IS A WIDE DIFFERENCE BETWEEN THE RATIO OF HEAVY AXLES TO TOTAL TRUCK TRAFFIC IN VARIOUS PARTS OF THE COUNTRY. /AUTHOR/
