  • Effect of Liquefaction on Lateral Response of Piles by Centrifuge Model Tests
    Effect of Liquefaction on Lateral Response of Piles by Centrifuge Model Tests
    Liu, L. ;
    Dobry, Ricardo
    1995-01-01 | PDF
    This article presents work conducted on the effect of liquefaction on lateral pile response. Many existing bridges are founded on piles driven through loose sand that may liquefy during earthquake shaking. Both lateral stiffness and lateral capacity of piles (friction or end-bearing) are very sensitive to the properties of the surrounding soil. In ...

  • Determination of Pavement Thickness with a New Ultrasonic Device
    Determination of Pavement Thickness with a New Ultrasonic Device
    Baker, Mark R. ;
    Crain, Kevin
    1995-01-01 | PDF
    The TxDOT spends a significant amount of money and effort to perform concrete coring. Coring is normally done to monitor the thickness and/or quality of PCC slabs during construction. Because a considerable amount of time is required to perform the procedure, it is done at widely spaced intervals. As a result, the most critical points, in terms of ...
  • Development of a Bonded Concrete Overlay ComputerAided Design System
    Development of a Bonded Concrete Overlay Computer-Aided Design System
    Rasmussen, Robert Otto ;
    McCullough, B. Frank
    1995-01-01 | PDF
    Bonded concrete overlays are increasingly being used to rehabilitate concrete pavements. Among other benefits, bonded concrete overlays (BCO) can reduce life-cycle costs and can expedite construction (thus lowering user costs and delays). Until recently, the design of bonded concrete overlays has been a tedious process. Several design methods are a ...
