Life Cycle Cost

Today’s current national and local economic conditions – combining reduced funding with high infrastructure needs – have elevated the importance of prudent spending. Decision makers exercising good stewardship practices can easily justify their decisions and choices to their constituents. Good stewardship practices include a detailed, logical, and documented pavement type selection process that includes a life-cycle cost analysis as a key component.

Life-cycle Cost Analysis – LCCA

The APA has developed life-cycle cost analysis software that uses the principles recommended by the Federal Highway Administration (FHWA) to compare the economics of alternative designs for a given road project. It’s easy to use, unbiased, and free. There are two versions: LCCA Original, a comprehensive program, and LCCAExpress, geared to less-complex projects. Both are available as free downloads at: Asphalt Pavement Alliance Economics

Pavement Type Selection

Pavement type selection, is the process that identifies the best pavement structure for a given application. Road agencies such as state DOTs and city/county public works departments use PTS processes, which may be as simple as specifying a certain type of pavement on the basis of traffic level, or as complicated as assigning weighting factors to more than a dozen characteristics and evaluating the outcome through a scoring system. The APA’s white paper on pavement type selection provides guidelines that agencies and others will find valuable:  Asphalt Pavement Alliance Pavement Type Selection
