Life Cycle Cost Analysis Comparison of Hot Mix Asphalt and ...

15/04/2021  Using higher RA contents in pavements results in lower life cycle costs. The RA material is a milled material obtained as a waste byproduct via the use of any rehabilitation technique, and it can be used by any recycling alternative in hot mix asphalt (HMA) [14]. Qiao, et al. [15] carried out a life cycle cost analysis (LCCA) for Interstate 95

Life Cycle Cost Analysis Comparison of Hot Mix Asphalt and ...

In the construction and maintenance of asphalt pavement, reclaimed asphalt pavement (RAP) is being widely used as a cheaper alternative to the conventional hot mix asphalt (HMA). HMA incorporated with a high RAP content (e.g., 40%), which is the most commonly used, may have prominent adverse effects on life cycle, performance properties, and related costs.

The “life-cycle costs”—money spent on road construction and maintenance over its lifetime—are significantly lower with Hot Mix Asphalt (HMA) than with concrete. Plus, maintenance on HMA pavements is a much less disruptive process. It can be completed quickly and economically. As a result, HMA pavement minimizes the often overlooked costs associated with traffic delays, detours and road ...
