Portable asphalt recycling trailers let crews reproject materials on-site, trimming hauling expenses by up to 40%.

Contractors using asphalt recycling systems report 15-25% faster project timelines due to reduced material sourcing. Cold planers and stabilizers enable in-place recycling, minimizing road closure durations. With recycled asphalt pavement equipment, agencies meet sustainability targets while maintaining DOT-spec pavement performance.

Next, let’s break down the machinery types powering these benefits.

Types Of Asphalt Recycling Machinery

Modern road rehabilitation relies on specialized tools to handle old pavement. Distinct methods demand custom-built units for optimal results. From in-place operations to mobile setups, machinery varies by project scope and recycling technique.

Hot In-place Recycling (HIR) Machinery

HIR machinery reworks worn surfaces without full removal. This method cuts material hauling by up to 80%, slashing costs for highway repairs. Units work in tandem to heat, loosen, and blend pavement layers.

Heaters and Pre-Mix Units

Infrared heaters soften existing asphalt up to 300°F, allowing scarifiers to break it apart. Pre-mix injectors add fresh binders like PG 64-22 directly into loosened material. This combo restores structural integrity in a single pass, saving 40% time compared to traditional methods.

Hot Mix Asphalt (HMA) Plant Integration

Larger HIR jobs feed reclaimed material into HMA plants. Conveyor systems transport millings to drum mixers, combining with virgin aggregates at 320°F. Plants with RAP capabilities process 200-400 tons hourly, maintaining mix consistency per Superpave specs.

Cold In-place Recycling (CIR) Machinery

CIR units tackle projects without heat, ideal for rural roads with base failures. This approach stabilizes pavement using additives like foamed asphalt or cement slurry, cutting CO2 output by 35% versus hot methods.

Cold Planers and Stabilizers

Cold planers grind pavement to 6-inch depths, creating uniform particles below 2 inches. Stabilization units follow, spraying binding agents at 50-100 gallons per minute while mixing. Final compaction yields a base layer strong enough for 10+ years of service.

Mobile Asphalt Recycling Units

Contractors favor mobile setups for jobs requiring rapid relocation. Compact designs fit standard trailers, while high-capacity models process 150 tons daily. Units slash transport needs by treating material on-site.

Portable Asphalt Recycling Trailers

Trailer-mounted systems handle parking lot patches or utility cuts. Built with 15-25hp motors, they crush and screen millings to 3/8-inch specs. Add-on bins store up to 5 tons of processed RAP for immediate reuse.

On-Site Recycling Systems

Larger mobile plants integrate crushers, dryers, and mixers on flatbed trucks. Capable of 50-75 tph output, these units supply hot mix for road widening or shoulder repairs. Dual-fuel burners trim fuel costs by 22% during prolonged runs.

Asphalt Reclaimers and Material Processing Units

Reclaimers transform stockpiled millings into graded RAP. Jaw crushers reduce chunks to 2-inch minus, while trommel screens sort by size. Advanced units add fractional rejuvenators to restore aged binders, pushing RAP inclusion rates to 50% in new mixes.

Choosing proper tools impacts both project budgets and pavement longevity. Up next: how these units function within full-cycle asphalt recycling workflows.

The Asphalt Recycling Process

Asphalt recycling turns old roads into new ones. Special gear breaks down used pave, cleans it, and blends it with fresh parts. This cuts waste and costs by up to 30% per ton.

Steps in Recycling Asphalt Pavement (RAP)

RAP recycling has three main steps. Each needs specific tools to work right.

Milling and Collection

Cold planers grind old roads into chunks. These machines chew up pave at 6-12 inches wide per pass. Front loaders scoop RAP into trucks. One milling rig can fill 20-ton haulers in 45 minutes.

Crushing and Screening

Jaw crushers smash RAP to 2-inch bits. Screens sort chunks by size—3/4″ for base layers, 1/2″ for top coats. Mobile units handle 200-400 tons daily. Fines under 1/8″ get reused as filler.

Mixing with New Material

Batch plants blend RAP with fresh bitumen and rock. Temp controls keep heat at 300-350°F. For every 10% RAP added, 1% new binder gets mixed in. Portable trailers make 150 tons per shift on-site.

Role Of Recycled Asphalt Pavement (RAP) in Production

RAP acts as both rock and glue in new mixes. Plants use 15-30% RAP in standard hot mix. High-RAP gear (up to 50%) needs extra burners and PG 64-22 binders. Reclaimers melt old pave at 500°F to pull out pure bitumen.
