Crushed stone is a versatile product that can be used in a wide range of applications from construction to road building and even agriculture. Processing this material may include reducing its size with a crusher, sizing the crushed material with a screen and conveying the material into different stockpiles.
Recycled Asphalt Pavement
The asphalt pavement industry has a long history of incorporating reclaimed asphalt pavement (RAP) into new asphalt pavement mix. In fact, Asphalt is America’s most recycled material making the asphalt industry is a leader in the use of recycled materials. Astec has a long history of building world-class tools to allow contractors and producers to collect and utilize this very valuable product.
Rail Loading & Unloading
Loading and unloading material at railways can be a challenge for any producer. Without having the appropriate equipment, retrieving and loading material can be a difficult and lengthy process. With dedicated systems, operators can avoid costly double-handling and avoid the use of dedicated haul trucks.
Ports & Terminals
Loading and unloading material at ports and terminals can be a challenge for any producer. Without having the appropriate equipment, retrieving and loading material can be a difficult and lengthy process. With dedicated systems, operators can avoid costly double-handling and avoid the use of dedicated haul trucks.
Construction aggregate is typically medium or coarse material that is used in construction applications. Processing this material may include reducing its size with a crusher, sizing the crushed material with a screen and conveying the material into different stockpiles.
Concrete is one of the most recycled materials in the world that can be repurposed several times over. Once the existing concrete is demolished or torn up, it needs to be processed for accurate shaping and sizing using a crusher and screen.
Loading & Unloading
Loading and unloading material from trucks, ports, terminals, stockyards and railways can be a challenge for any producer. Without having the appropriate equipment, retrieving and loading material can be a difficult and lengthy process.
Sand & Gravel
Sand and gravel are aggregates that are gathered from naturally occurring deposits. These aggregates, when gathered, may contain clays, silts and other deleterious material that needs to be processed out for commercial-grade products. Reduction and sizing can be accomplished with a variety of crushers and screens. Once the material is accurately processed, it can be used for road building, construction materials and a variety of other applications.
Surface mining involves removing soil and bedrock to reach resource deposits. The most common types of surface mining are strip mining and open-pit mining.
Underground mining involves digging into the earth and creating tunnels and shafts to reach hard rock deposits. The coarse ore that is removed from the stope can be crushed using a jaw or cone crusher or crushed using a rock breaker.
There are two main classes of aggregates: natural and manufactured. Deleterious material needs to be removed from both classes of aggregates. Processing these materials typically requires various steps including reduction and sizing and also may include dewatering and sorting. Producers can use a variety of crushing, screening, dewatering and conveying equipment to meet their desired specifications.
Railroad Tie Recycling
The creosote treated railroad ties are a valuable energy source, once they have been broken down into a manageable and consistent size.
Agriculture & Nursery
Processing nursery and agricultural waste with a horizontal grinder offers sustainable recycling solutions.
Cold-in-Place Recycling (CIR)
Cold in-place recycling (CIR) is a paving process where instead of applying all-new Hot Mix Asphalt (HMA), you treat remove and treat the existing asphalt with bituminous and/or chemical additives and then use it to pave the road. It normally involves a recycling train consisting of recycling agent tankers, a milling machine, an asphalt paver, and a combination of compaction equipment.
Blower trucks are beneficial when landscaping residential, commercial, and HOA settings. They facilitate easy and fast application of mulch, compost, and terra seeding through pneumatic delivery.
Fiberboard is an engineered wood product formed by breaking down wood into fibers, and using a binder to form them into panels. Fiber board is created by debarking logs and them chipping them with a disk chipper.
Asphalt Reclamation, also known as Full Depth Reclamation (FDR), is a cost-effective method of pavement rehabilitation. During FDR the full thickness of the asphalt surface and a portion of the underlying base is uniformly graded and pulverized to serve as the base for a new road. Additives such as cement or asphalt emulsion are often incorporated to increase strength. The result is a homogenous layer with improved structural capacity.
Motor Sports Paving
Motor Sports Paving requires nonstop paving, precise mat thickness, and consistent paving practices. The HMA mixture needs to be consistent in terms of temperature and consistency. The resulting pavement must be able to withstand massive stress.
Peterson horizontal grinders and drum chippers are an ideal tool for processing damaged wood from private timberlands, national forests, pulpwood plantations, and hazardous trees near roadways and other infrastructure.
