Free RECYCLED ASPHALT DELIVERY in Sanford, FL

Reclaimed asphalt pavement (RAP) is the term given to removed and/or reprocessed pavement materials containing asphalt and aggregates. These materials are generated when asphalt pavements are removed for reconstruction, resurfacing, or to obtain access to buried utilities. When properly crushed and screened, RAP consists of high-quality, well-graded aggregates coated by asphalt cement.

Asphalt pavement is generally removed either by milling or full-depth removal. Milling entails removal of the pavement surface using a milling machine, which can remove up to 50 mm (2 in) thickness in a single pass. Full-depth removal involves ripping and breaking the pavement using a rhino horn on a bulldozer and/or pneumatic pavement breakers. In most instances, the broken material is picked up and loaded into haul trucks by a front-end loader and transported to a central facility for processing. At this facility, the RAP is processed using a series of operations, including crushing, screening, conveying, and stacking.

Although the majority of old asphalt pavements are recycled at central processing plants, asphalt pavements may be pulverized in place and incorporated into granular or stabilized base courses using a self-propelled pulverizing machine. Hot in-place and cold in-place recycling processes have evolved into continuous train operations that include partial depth removal of the pavement surface, mixing the reclaimed material with beneficiating additives (such as virgin aggregate, binder, and/or softening or rejuvenating agents to improve binder properties), and placing and compacting the resultant mix in a single pass.

Crushed asphalt is most commonly used for roads and parking lot construction, such as:

• In paved roads as aggregate base, aggregate subbase, and shoulders
• In gravel roads as surfacing
• As base for building foundations
• As fill for utility trenches
• Road resurfacing
• Driveway resurfacing
• Parking lot resurfacing
• Material use for under buildings
• Build-up ground for special products

What Other Project Types Are a Good Fit for Crushed Asphalt?

Asphalt surfaces are hard and smooth, making them suitable for a wide range of recreational activities as well. The materials can be also used on steeper alignments without significant erosion concerns. In addition, research has shown that crushed asphalt pavements made with recycled materials perform the same as or better than those made with virgin materials.
