Final report on road test one-MD : effect of controlled truck axle loadings on concrete pavement.
Tests were conducted on a 1.1-mi. section of portland- cement-concrete pavement near La Plata, Maryland, to determine the relative effects of four different axle loads on a concrete pavement. The loads employed were 18,000 lb. and 22,400 lb. on single axles, and 32,000 lb. and 44,800 lb. on tandem a...

| Summary: | Tests were conducted on a 1.1-mi. section of portland- cement-concrete pavement near La Plata, Maryland, to determine the relative effects of four different axle loads on a concrete pavement. The loads employed were 18,000 lb. and 22,400 lb. on single axles, and 32,000 lb. and 44,800 lb. on tandem axles. There were four separate test sections with trucks selected for each section to obtain the highest practicable rate of acceleration between 10 and 40 mph. on the existing road profile. Controlled-traffic tests were conducted from June through December 1950, soil and strain tests made in 1951. The analyses of these data, which included 6,000 soil tests and 12,000 strain and deflection readings, were completed in April 1952. |
