ABSTRACT:
A system for producing asymmetrical barrier wall section assemblies from a combination of standardized precast concrete components of complex cross section and custom dimensioned precast components of simple cross section includes first and second half-sections having symmetrical inclined outer face portions, at least one filler block for supporting the second half-section so that its inclined outer face portion is vertically displaced above the inclined outer face portion of the first half-section, and a filler panel for filling a gap between the top of the first half-section and a top portion of the second half-panel. The at least one filler block and the filler panel are essentially rectangular in cross section, so that they can be cast with any desired height dimensions within a predetermined range in simple open-top box molds having one adjustable side. Various arrangements for securing the precast concrete components together include lateral volts and vertical undercut channels containing slidably positionable nuts, cement grout filled vertical roughened recesses on vertical interfaces of the components, and longitudinal interengaging extensions and depressions on horizontal interfaces of the components. With appropriately selected dimensions of the first and second half-sections, symmetrical assemblies can be produced with the first and second half-sections alone or optionally including a filler panel.
