This study was intended to evaluate the air void characteristics of concrete in an attempt to identify, quantitatively or semi-quantitatively, different types of voids and to predict their influence on strength and durability. At the outset, it was anticipated that total air contents and water-- cement ratios of concrete mixtures would reflect the

The study reported here was performed to extend the body of knowledge concerning the use of internally sealed concrete to protect bridge deck reinforcing steel. A laboratory determination of the properties of the wax and concrete used and a field evaluation of a method of heat treatment were made. The experimental structure was a three-span bridge

Right turn on red (RTOR) maneuvers have been permitted at signalized intersections in Virginia since 1972. However, until January 1, 1977, following a study requested by the General Assembly, the maneuver was restricted to intersections at which a sign was posted to inform the motorist that RTOR was permitted. Under the pre-1977 legislation RTOR wa

The need for a suitable method of designing the thickness of overlays and predicting the performance of the overlaid pavement has recently been recognized. The AASHTO Road Tests included studies on 99 overlays, but they failed to produce conclusive results and hence provided no guidance for overlay designs. In the present investigation the raw data
