Life-Cycle Cost Analysis
How it works
HMA pavement design begins with a strong base layer that absorbs and diffuses the stress of heavy traffic, preventing the initiation of cracks. A strong, load-bearing intermediate layer is topped by a smooth, rut-resistant surface layer that seals out moisture and deicing materials. Altogether, HMA pavements can handle the toughest traffic punishment.
Because construction cost less initially, and proper maintenance extends the life for decades, HMA pavements last longer and cost less than concrete. HMA pavements require only periodic surface restoration, providing a smooth, durable pavement for decades. Maintenance is quick, cost-effective and less disruptive than with PCC pavements.
Hot Mix Asphalt (HMA) Life-Cycle Costs - Fast Facts
- Reduces costs for initial construction.
- Requires less maintenance over the life of the pavement.
- Repaired and maintained cost-effectively with HMA overlays instead of complete removal and reconstruction with concrete.
- When maintenance is needed, HMA offers the widest variety of alternatives geared to solve the precise problems on the roadway.
- Can be overlaid to add structural capacity to account for increased traffic loading.
- Eliminates the need for costly reinforcing materials, which are subject to corrosion, which lead to more frequent and more costly repairs.
- Properly designed and constructed HMA pavements will last 50 years or more with occasional resurfacing, relieving road agencies of the need for costly, time-consuming and disruptive reconstruction.
- HMA can be recycled (milled and replaced along with fresh materials), saving dollars and preserving nonrenewable natural resources.
