Get answers you can count on with the new Asphalt Annualized Lifecycle Calculator
Two important factors come into play in the design of any asphalt mix: Initial Cost and the Projected Years of Life. Engineers, contractors and pavers all wrestle with decisions on which mix will yield the longest pavement life for the best value in dollars spent. To aid in this endeavor, engineers use an equivalent annualized cost approach called Life Cycle Cost Analysis (LCCA), to aid in the decision.
Phil Blankenship, P.E., has combined his years of experience in the asphalt industry with a wide range of documented results from studies of asphalt pavement to create the Asphalt Annualized Lifecycle Calculator, an online tool that can help determine both lifespan and payoff time frames.
“Tools like this are important to use, because they can evaluate various mixes and lengths of time to see how they compare,” said Blankenship, an independent industry consultant who also serves on the Surface Tech Advisory Committee.
One critical feature of the new calculator is its ability to compute results in terms of today’s dollars (net present value), an important capability to evaluate the time value of the pavement investment . The calculator allows a user to compare several mixtures and combine each with various additives to see how the estimated value of the mixture will compare in cost to a standard.. The current estimated life of US pavement surfaces averages about nine years before needing replacement. Additionally, the calculator takes into account the salvage value of the pavement to produce results that compare equally across various mix designs in terms of cost.
“The objective for this calculator was to achieve an apples-to-apples comparison,” said Blankenship.
With construction costs rising, it becomes ever more critical to seek out new ways to predict return on investment (ROI). This new calculator shows you what can happen when you test various mixes against their projected lifespans. In short, it’s a try-before-you-buy tool that can save you both money and buy you time.
