Paving Cost Comparisons: Warm-Mix Asphalt Versus Concrete

Paving Cost Comparisons: Warm-Mix Asphalt Versus Concrete Key Findings Concrete pavement enjoys both an initial and life cycle cost advantage over HMA as well as the most cost effective WMA case for many roadways. WMA production uses less fuel than hot-mix asphalt (HMA): With temperature reductions of up to 100°F, burner fuel consumption can be reduced by up to 50 percent of HMA

PDF Methods of Rehabilitating Pavements with Moisture Damaged

Stripping is moisture damage to old hot mix asphalt (HMA) layers, which are often buried several inches down in the pavement structure. Certain aggregates, such as gravels, are known more susceptible to stripping. While the current generations of asphalt mixtures often use

Gradation and Size – Pavement Interactive

Gradation and Size. The particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material. In HMA, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue

Placement - Pavement Interactive

Placement. Mix laydown involves everything used to place the delivered HMA on the desired surface at the desired thickness. The asphalt paver is the principal machine involved in mix laydown and is assisted by the material transfer vehicle (MTV) in some instances. Figure 1: Asphalt Paver. Figure 2: HMA Placement.

PDF Performance of Steel Slag Aggregates in Hot-Mix Asphalt

The trial project included a one-mile trial section of hot-mix asphalt pavement constructed using steel slag aggregate as a replacement for 20 percent of the coarse aggregate in the HMA. The trial section was part of a project that improved five miles of SR 203 by grinding out the existing pavement and replacing it with new pavement.

and grade, meeting grade of other adjacent pavements and structures, etc. The most difficult part of designing hot mix asphalt overlays for flexible pavements is the determination of the properties of the existing pavement. Subgrade and subbase properties can be measured by conducting NDT. The subgrade and subbase must be at the equilibrium
