Cement; Durability tests; Life cycle costing
Investigating the performance of low cementitious paving mixes in terms of its early-age characteristics, potential durability issues, long-term serviceability, and life cycle costs will lead to a stronger understanding of the application and practice. Other benefits the state will receive from the results and conclusions of this research include: 1. Material cost savings: A reduced cementitious mix will cost less than a standard mix. A 470 lb/CY mix would amount to a 1 bag reduction of cement and approximately a $6/CY savings. 2. Potentially longer pavement life resulting in reduced life cycle costs: Reducing the total amount of cementitious materials would reduce the shrinkage cracking potential and ultimately extend the service life of the pavement. 3. Reduced environmental Impacts: The materials saving, especially the cementitious materials, will ultimately lower the carbon footprint, therefore reducing the impacts on the environment. 4. Safer and more reliable serviceability: Less cracking potential and the higher resistivity of a deicing chemical attack will result in a safer travel environment for the public.
