Life-cycle Cost. Life-cycle cost analysis is one of the tools by which pavement structures are evaluated and eventually selected by pavement owners. The life-cycle cost of a road includes the money spent on initial construction of a road, maintenance over its lifetime, and the costs to users for their delays during maintenance and reconstruction.
ASPHALT PAVEMENT LIFE CYCLE. As pavement progresses through its 20 year, average performance life cycle, it changes along the way. Its appearance and functionality diminish over time. This aging process begins immediately after construction even though these early changes are impossible to see.
Life-Cycle Cost A new position paper from the Asphalt Pavement Alliance (APA) articulates an appropriate and non-biased method for life-cycle cost analysis (LCCA) that follows guidelines from the Federal Highway Administration.
Pavement life cycle depends on a variety of factors, including how well they are constructed initially, the weather, amount and weight of traffic and
Asphalt is an organic material and is thus susceptible to the actions of nature. From the day it is placed, asphalt pavements begin to deteriorate. Ai

This section discusses the basic pavement life-cycle and how maintenance and rehabilitation affect this life-cycle. All pavement deteriorates over time.
2006a);(Santero et al, 2011)). For pavement, the life cycle includes material production, construction, use, maintenance and end-of-life (EOL) phases. Figure 1 shows a general pavement life cycle.

KEY WORDS: Asphalt pavements, life cycle assessment, recycling, sustainable construction. 1 INTRODUCTION The use of recycled materials in pavement construction needs prescriptive assessment of the associated environmental impacts including energy consumption, emissions and leaching, etc. A life cycle approach is gaining ground in
Good stewardship practices include a detailed, logical, and documented pavement type selection process that includes a life-cycle cost analysis as a key component. Pavement Type Selection - PTS. Pavement type selection, or PTS, is the process that identifies the best pavement structure for a given application.

The increasing use of recycled materials in asphalt pavements asks for prescriptive environmental assessment on associated impacts such as the energy and CO 2 footprint. Accredited by a number of industries already, life cycle assessment (LCA) is being accepted by the road industry to measure and compare the key environmental impacts
Today’s current national and local economic conditions – combining reduced funding with high infrastructure needs – have elevated the importance of prudent
