Introduction â–Ş

Asphalt pavement refers to any paved road surfaced with asphalt. Hot Mix Asphalt (HMA) is a combination of approximately 95% stone, sand, or gravel bound together by asphalt cement, a product of crude oil.

Purpose of Pavement ▪

Smoothness.

▪

Drainage.

▪

Load Support.

▪

All weather operation.

▪

Direction and Guidance.

Top Benefits of Asphalt Pavement • It costs less to construct and maintain asphalt than alternative pavements.

• Asphalt construction projects can be completed more quickly than alternative pavements.

• Asphalt pavements are the smoothest pavements.

• Asphalt pavements generate less noise than alternative pavements.

• Smoother roads reduce the wear and tear on vehicles because there are fewer bumps on the road.

• Unlike concrete, asphalt roads can be applied one at a time, meaning only a lane or two will be closed to traffic.

Types of Asphalt Pavement Asphalt is the most recycled, reused and versatile pavement material.

Porous Asphalt. Porous asphalt has been around since the mid 1970s.

This type of asphalt is used in parking lots to enable water to drain through the pavement. This pavement solution is cost-effective and can last for more than twenty years.

Perpetual Pavement. Perpetual pavement is a combination of asphalt and the multi-layer paving design process. They are durable and longlasting. Installation of perpetual pavement is not time-consuming.

Warm-Mix Asphalt. Warm-mix asphalt is produced the same way that hot-mix asphalt is, except it is 50-100 degrees Fahrenheit lower.

Reducing the temperature of the asphalt has a few benefits. These include reducing fuel consumption and the production of greenhouse gases.

Thin Overlays. Thin overlays improve ride quality and reduce pavement distress, noise levels, and life-cycle costs. It is produced by using warmmix asphalt and recycled materials.

Quiet Pavement. Paving roads with asphalt significantly reduces the noise inside and outside of homes and businesses. Switching up the pavement of a noisy road with stone-matrix asphalt or open-grade friction course mix has been proven to reduce highway noise.
