Texas State University and The University of Texas at Austin Project 0-6749 : Feasibility Study of Two-Lift Concrete Paving

Two-lift concrete paving (2LCP) involves placing two layers of concrete (wet-on-wet) instead of a single homogeneous layer, as is typically done in the United States. 2LCP offers the opportunity to optimize the use of local aggregates and recycled materials to produce an economical, durable, and sustainable pavement system with the most desirable surface characteristics (improved skid resistance and reduced noise). Challenges of 2LCP include having the proper paving equipment, pavement construction management, the right mixture proportions to use local materials in the bottom lift, which results in an economical pavement placement, and the proper proportions and materials to ensure adequate surface friction and abrasion resistance in the top lift. This study is to deliver a feasibility analysis and cost assessment of this alternative method of paving with current equipment and materials, but using more of the plentiful local resources (that might not be suitable as the surface course), instead of relying on imported materials.
