  • Detection of Voids Underneath Continuously Reinforced Concrete Pavements
    Detection of Voids Underneath Continuously Reinforced Concrete Pavements
    Birkhoff, John W. ;
    McCullough, B. Frank
    1979-08-01 | PDF
    The basic assumption in pavement design is that there is full support through out the length of the pavement. When a void developes, this is not true. This report investigates three methods of detecting voids underneath continuously reinforced concrete pavements. The methods; deflection, pumping, and vibration, are evaluated to find which has the h ...

    Ma, J. C. M.
    1979-08-01 | PDF
    The primary factors to consider in the thickness and reinforcement design for continuously reinforced concrete pavements are the structural response variables; crack spacing, crack width, and maximum steel stress. They plant an important role in the outcome of the pavement performance and can be related to the major distresses common to CRC pavemen ...

  • Draft for Design Manual Chapter 5 Deciding on Flat vs Hump Yard
    Draft for Design Manual, Chapter 5: Deciding on Flat vs. Hump Yard
    Wong, Peter J
    1979-07-11 | PDF
    We address the questions of whether a flat or hump yard should be built, or perhaps more importantly, whether an existing flat yard should be rehabilitated into a hump yard. One can classify a flat yard as a labor-intensive facility, whereas a hump yard is a capital-intensive facility. For this reason, it has been traditional to build flat yards fo ...
