    TXLINE: A Computer Model for Estimating Pollutant Concentrations Downwind of a Roadway
    Bullin, J. A. ;
    Rodden, J. B.
    1983-03-15 | PDF
    A state-of-the-art computer model called TXLINE (Texas Line Source Dispersion Model) was developed to predict pollution concentrations near roadways. The model has a strong theoretical foundation, based on non-Fickian, gradient transport diffusion theory. The model does not assume constant wind speed and eddy diffusivity as is usually the case with ...

    Identification and quantification of the extent of asphalt stripping in flexible pavements in Oregon : phase I.
    Hicks, R. G. ;
    Wilson, James E.
    1983-03-01 | PDF
    This report is the first phase of a study in Oregon to evaluate the effect of material sources, void content and additive type on the retained strength (AASHTO T-165) or retained modulus (NCHRP 196). A total of 20 projects were evaluated. The results clearly indicate that material and additive type affect asphalt-aggregate interaction.

  • Raised markers placed in pavement grooves
    Raised markers placed in pavement grooves.
    Shepard, Frank D
    1983-01-01 | PDF
    Previous research has noted the feasibility of placing raised pavement markers in grooves cut into the pavement to prevent them from being damaged by snowplows. Because of the potential economic benefit of using this procedure in place of the one presently in use to install a durable, effective marking system for night-wet roadway delineations, a d ...
