Abstract:

Pavement performance and behavior have been monitored for up to five years on roads in central Brazil. Surveys of surface conditions were made at 4- to 6-month intervals to obtain rutting, cracking, and patching data. At periodic intervals road roughness and deflection measurements were obtained by using Mays meters and the Benkelman beam and Dynaflect, respectively. Test pits were dug to measure in situ density, California bearing ratio (CBR), and moisture. Laboratory testing produced material gradings, Atterberg limits, laboratory CBR, and density of the road materials. This information, together with data on traffic volume and weight, is analyzed to produce equations that predict pavement roughness, patching, and cracking. Rutting was found to be slight in the study area and probably will not trigger maintenance. The influence of slurry sealing on cracking progression is also investigated. A model for the initiation of cracking after slurry sealing reflects the experience that the slurry seal is ineffective in sealing pavements. (Author)
