    The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.2 percent in May, before seasonal adjustment, to a level of 162.8 (1982-84=100). For the 12-month period ended in May, the CPI-U increased 1.7 percent. The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) rose 0.3 percent in May, prior to seasonal adjustmen ...
  • Development of a Rolling Dynamic Deflectometer for Continuous Deflection Testing of Pavements
    Development of a Rolling Dynamic Deflectometer for Continuous Deflection Testing of Pavements
    Bay, James A. ;
    Stokoe, Kenneth H. II
    1998-05-01 | PDF
    A rolling dynamic deflectometer (RDD) was developed as a nondestructive method for determining continuous deflection profiles of pavements. Unlike other commonly used pavement testing methods, the RDD performs continuous rather than discrete measurements. The ability to perform continuous measurements makes RDD testing very effective for quickly ch ...
