Grasan Portable Inclined Screen Plants

Wacker offers a new generation of ride-on asphalt rollers to the industry. The RD 12-90, RD12A-90 and the RD 16-90 offer various enhacements to improve performance and operator comfort.

RD 12 series
Modeled after the RD 11, the RD 12 rollers offer a number of new features suggested by asphalt contractors. It starts with the elimination of overhang on the back of the machine. This was achieved by a redesigned frame and operator’s platform and the use of a pressurized water system.

This new design provides excellent visibility for the operator and allows for the roller to get right to the edge of the asphalt for a complete and smooth finish.

These versatile rollers offer improved performance with an increase in compaction force of 15 percent. The exciter frequency has been increased resulting in faster travel speeds which allows for more efficient and smoother finishes.

The RD 12 rollers feature dual-drum drive and articulated steering for extremely accurate control. The hydrostatic drive with infinitely variable forward and reverse operation and even accelerations and stops guarantees a smooth asphalt finish. Front drum vibration with static rear drum provide for an excellent asphalt finish.

Also contributing to the excellent finish is a new pressurized water system. The advantage to this system is that it allows for a much more efficient and consistent water flow. The water pump timer is adjustable to eight positions which allows the operator to better control the water flow, based on the asphalt conditions. Because this system is more efficient, the overall size of the water tank could be reduced, but the running time per tank of water has been increased.

This redesign also contributes to improved operator comfort including significantly reduced whole body vibration and quieter operation. Contractors will appreciate the more spacious operator platform and sloped hood for excellent visibility. The roller continues to feature the user-friendly control panel and right hand forward and reverse lever with integrated vibration control for easy operation.

Wacker’s new one-ton class RD 12 ride-on asphalt roller series is offered with two engine options. The RD 12-90 comes with a 20.5-hp Wacker engine and comes with a complete two-year bumper to bumper warranty.

The RD 12A-90 is equipped with an 18-hp Honda model. Both units have an operating weight of 2,490 pounds, 35.4-inch drum width and centrifugal force of 3,400 pounds.

The RD 12 series is suited for compaction of level sublayers and finish layers on road repairs, driveways, parking lots and any asphalt surface.

RD 16-90 asphalt roller
Also new to Wacker’s asphalt roller line is the larger RD 16-90. This new 1.5-ton diesel-powered unit offers the same new features as the RD 12 series including the overall redesign to eliminate overhang, increased compaction performance, pressurized water system and ergonomic enhancements.

The CE-compliant RD 16 also offers additional features to enhance performance and operator comfort. The centrifugal force of the RD 16 has been increased 30-percent over previous models and offers thicker drums for additional weight, plus dual drum vibration for outstanding overall performance and a quality asphalt finish.

The RD 16 also offers as standard a foldable rollover protection systems (ROPS) for easier transportation and storage, a rotating beacon light, working lights, horn and back up alarm. The ergonomic operator’s platform features a fully adjustable suspension operator’s seat for maximum comfort.

Wacker’s new RD 16-90 is powered by a 26.8-hp Lombardini diesel engine. The unit has an operating weight of 3,274 pounds and with both the front and rear drums in the vibration mode, it can produce up to 6,800 pounds of total centrifugal force. The RD 16-90 is designed for compacting base and finish layers of asphalt as well as granular material in confined areas. It’s ideal for applications such as parking lots, driveways and shoulder work. 

Although concrete may seem pretty tough, it actually is vulnerable to many environmental factors. People often overlook the fact that concrete is porous. And as with porous surfaces, moisture, stains, molds, and other environmental hazards can seep in, wrecking havoc on your beautiful concrete surfaces.

Your concrete is always vulnerable to water. These porous surfaces will allow moisture to loosen your vinyl tiles or ruin your carpet.

How does water get in my concrete, (and how do I stop it)?

Water can enter concrete in two ways: from the top side or from the ground. Water entering from the top is called positive moisture. It comes from rain and other liquids that spill on the concrete surface. Ground moisture is called negative moisture. It comes from the natural moisture of the ground over which the concrete is laid.

Concrete surfaces act like sponges when exposed to water. It will draw water until it is saturated, or if there is no more water available. It will then disperse the water until it reaches equilibrium state.

What does water do to my concrete?

Water may cause many processes that can lead to noticeable damage. Water causes the rebar to rust. This in turn weakens the concrete.

Water also activates alkali disintegration. During the curing process of concrete, the alkali in the concrete becomes dormant. As water seeps into the concrete the alkali begins to react again with the concrete around it. This destroys the concrete from within.

Water is also causes mold, mildew and algae to grow. Mold has been known to influence severe health problems. Algae, on the other hand, cause the concrete to become slick and discolored while mildew often give off a bad odor and stains organic materials.

Up to 60% of homes have basements that suffer from this sort of problem. This could seriously affect the resell value of your home and make your home a health hazard to its occupants.

The moisture must be stopped to stop the damage.

To protect your concrete walls or floors, you need to have them protected with a concrete sealer. Concrete sealers protect concrete from deterioration brought about by road salt, stains, oil, moisture, and molds. It also provides a layer of protection that allows for easier sweeping and cleaning.

You will most likely need only one application of concrete sealant to keep your concrete surfaces protected.

Needed Equipment

First of all, you need to assemble the needed equipment. First of all, you must wear protective clothing since you are about to work with potential irritants. Gather a stiff brush and a water bucket. You will also need some rubber gloves, goggles and small-particle filter to protect you against chemical agents. You will also need some paintbrushes and a paint roller. Make sure there is proper ventilation at the place you are to work with the concrete sealer.

How to Apply

   1. Clean the Floor. Your surface must be free of dirt, grime, grease, and oil. The stiff scrub brush will help remove stubborn stains. Use a commercial cleaner to help remove the dirt. Stubborn stains might need some soaking in a detergent solution before they can be removed. Rinse thoroughly with clear water. A second application may be required.
   2. Apply Sealer: Before painting the floor, make sure you test the sealer on a small patch of floor. This will tell you if the floor is clean enough or if there are still imperfections that should be remedied. Uneven density in the concrete may result in a blotchy appearance that may be undesirable. Apply the sealer using a paint roller with an extension handle. Use the brush to cut in when working the perimeter. Start in a rear corner and work your way out of the area you are working on. Work the sealer into the surface. Spread it in a way that all the puddles are eliminated and apply a relatively thin uniform coat. You will probably only need one coating. Allow the sealer to dry. This will take a few hours.
   3. Clean Up: Don’t forget to wash up with soap and warm water immediately afterwards. Remember you had just dealt with a potentially hazardous chemical. Always keep safety in mind as you work on your area. Also, dispose of the roller and the brushes you used for the job. Concrete sealers may require that you use these equipments just once.

The Army is always completing hundreds of construction projects and Concrete and Asphalt Equipment Operators are integral to this process. Airfields, roads, dams and buildings can’t be created without moving tons of earth and building materials. Construction equipment operators use bulldozers, cranes, graders and other heavy equipment to complete these kinds of projects.

Concrete and Asphalt Equipment Operators are responsible for supervising or operating all equipment used in concrete and asphalt production and paving.

Some of your duties as a Concrete and Asphalt Equipment Operator may include:

    * Producing concrete with a concrete mobile mixer
    * Assisting in the building and operation of asphalt producing plant
    * Operating asphalt distributors, aggregate spreaders and asphalt kettles
    * Assisting in the operation of asphalt paving and surfacing equipment
    * Assisting in the performance of combat engineer missions

Training:

Job training for a Concrete and Asphalt Equipment Operator consists of nine weeks of Basic Training, where you’ll learn basic Soldiering skills, and four to 12 weeks of Advanced Individual Training, including practice operating construction equipment. Part of this time is spent in the classroom and part in the field. You’ll learn:

    * Operation of different types of construction equipment
    * Maintenance and repair of equipment

Helpful Skills:

Helpful attributes include:

    * An interest in operating heavy construction equipment
    * A preference for working outdoors

Hard-surfaced pavements, which make up about 60% of U.S. roads, typically are constructed with either hot-mix asphalt or portland cement concrete (commonly referred to as “asphalt” and “concrete,” respectively). Of those roads, more than 90% are asphalt. Both asphalt and concrete pavements can be designed for long life with routine maintenance and can be constructed as quality products. However, there are many practical, economical, and even political reasons for choosing one type of pavement material over the other for pavement construction.

To understand the practical and economic reasons, a simplified look at how the pavements function is necessary. Asphalt pavements are typically constructed in several layers with a hot bituminous surface. The asphalt may be constructed over a gravel base layer, stabilized subgrade, or natural soils. These pavements are referred to as “flexible” because the total structure flexes under traffic loads. Concrete pavements are constructed with a concrete surface typically poured in one lift over the soils. These pavements are referred to as “rigid” due to the greater stiffness of the material compared to asphalt.

A few reasons asphalt pavements are selected include:
# Asphalt pavements have a lower initial construction cost, allowing agencies to pave more with less funding.
# Traffic noise is generally lower with asphalt pavements.
# Newly constructed asphalt pavements can have a very smooth ride.
# The flexibility of asphalt pavement can help it perform well in areas of expansive soils, especially when coupled with proper subgrade stabilization.
# Routine maintenance can be performed quickly, reducing service interruptions.

Some reasons concrete pavements are selected include:
# Concrete pavements are typically more expensive initially; however, the life-cycle cost of concrete can be comparable to that of asphalt.
# The increased stiffness of concrete makes it able to withstand heavier wheel loads without risk of rutting. This is the main reason concrete pavement is used for bus stops, areas of heavy truck traffic, and even loading docks and warehouse slabs.
# Since concrete does not rut, there is less risk of water accumulation on the pavement, which reduces the chance of vehicles hydroplaning.
# During construction, concrete is less dependent upon the subgrade soils and is better able to “bridge” soft spots.
# Routine maintenance can be reduced for some concrete pavements. When maintenance is required, it can be smaller in scope when having to replace select concrete areas.
# Concrete can be colored and/or stamped into a pattern that can be aesthetically appealing.

While there are some recognized benefits to selecting one material over the other, many political factors come into play. Many issues, such as life expectancy, ease and cost of maintenance, and long-term smoothness are hotly debated in the industry. In the end, personal preference and construction costs are often the deciding factor in whether to select asphalt or concrete for the paving material.
