Advanced Tools and Equipment for Non Destructive Testing

When building pavements, it is important to design them in such a way so that they do not get overloaded. A tool that can help with this is the falling weight deflectometer. It is very helpful in analysing the properties in the physical sense. Using this tool, the life expectancy of the pavement can be easily determined. There are products that have been designed according to the highest international standards. They are simple in structure and are available in vehicle towed and mounted versions.

The cable blower is yet another machine that is very helpful in the engineering department. It allows for easily installation and setting up of wires with the help of a hydraulic pusher. It is set on a frame that is light in weight. This facilitates easy transportation. This is a very safe and effective way of having them installed.

The portable non destructive testing equipment is available in the market today. They can be used to safely examine metal, or concrete. With this you will get to know how good the quality of the concrete is. They provide instant and very accurate details about the material that is being tested. The receiver is very sensitive and these machines can be used on dense surfaces as well. They are also built to be rugged and durable. 

Well Engineered Under-Ground UtilityPenetrating Equipment

Machines that are used for underground utility locating are manufactured and sold by some of the best companies in the world. They have many years of experience in the engineering industry. Sometimes pipes and other such objects can cause a lot of disruption in your work if you hit any of them during an excavation project. Cable avoidance tools can help to prevent this from happening by showing the accurate location of such items that are buried. They can be used at night or during the day as well. There is a locating receiver that is equipped with some of the most advanced technology ever made.

Fiber optic cable blowers are designed to be very durable and to function with maximum efficiency. These powerful machines help to install wires with absolute ease. There is a hydraulic power pack, pusher, and an air box that combine to deliver the cables at force that ranges between zero to one hundred kilograms. Some of them are made to handle micro wires that are being used all over the world today. The force of the push can be changed to the level of the stiffness.

Ground penetrating radar equipment can be used to map the sub-surface regions that are below the groundl. The software for these tools is specially made to handle both 3D as well as 2D graphics. This is of great help in detecting any anomalies so that you can take the corrective steps in advance. It is also helpful in preventing accidents at the site.

What Is The Depths That the Ground Penetrating Radar Can Reach?

GPR or Ground penetrating radar is a device that allows you to “see” underneath the surface using pulses or electromagnetic waves through the antenna. No matter how modern the equipment is, it’s not going to supplant the law of physics. So there will always be constraints depending on the condition on the ground. A monitoring screen is also present so the operator can study the results which are delivered in a matter of nanoseconds.

How deep can it see?

The problem is that the GPR can’t probe far through the rocks, soils or concrete. How does that happen? It’s called signal interference. The efficacy of radio waves will decline when they hit energy absorbing materials until they become undetectable. Try picturing out talking to a cell phone and entering a tunnel and the signal dies out. The concept is similar.

Lowering frequency

If you lower the frequency of the ground penetrating radar, you improve your chance of being able to see deeper. But there’s a drawback to this method. As you dial down the frequency, the resolution suffers. Second, the radio pulses diffuse instead of traveling as waves and you would be better off using the eddy current measurement machine which is another non-invasive way to probe the subsurface.

Another way to improve depth penetration is to increase the power of the transmitter but you will be limited by government regulation, which specifically limits the amount of radio emissions. If the transmitter power is increased past the limit, it will interfere with cell phone or TV signals.

Latest Testing Equipment Makes Life Easier For Road Contractors

Light weight deflectometer or LWDs as they are called, are used regularly in road and highway construction to determine the compaction quality of the earthworks that is done before and during any kind of road or highway construction.

Sophisticated Instruments

The other highly sophisticated road testing equipment - the Falling weight deflectometer(FWD) is an essential requirement for the road building contractors and inspectors to get an  idea about the ability of road or pavement to handle any future expected traffic. A big advantage of using this equipmentfor this kind of analysis is safety and ease of operation along with instant results; it takes 28 seconds to perform the standard test.

Being portable, the light weight deflectometer is favored by many road inspectors and contractors as they can get the test results on the spot and make the necessary adjustments or corrections.It isused to determine the dynamic modulus of deformation of soil (resilience) in the range Evd = 15...70MN/m .The FWD works by imparting an impulse weight simulating traffic load on the surface being tested and measuring the deflection waves. This gives an accurate picture of the structure of the road substrata and the surface.

Ease of Use

The waves created by dropping appropriate weights is picked up by the geophones  at the base of the falling weight deflectometer and the readings are communicated automatically by a communication port to a display unit which stores and/or prints out the readings. This type of testing allows automatic load adjustment for greater accuracy with wide load range of 0-150KN. Another advantage of using the FWD, you can repeat the tests as many times as required, and hence cover vast stretches of road /runway at one go 

Use the Latest Road Testing Equipments for Best Results

Building road, highways, pavements or something more complicated like an airport runways or taxiways is not something that can be done by ordinary contractors, but by someone who has a lot of experience. In an effort to minimize repair work, many of these works are regularly tested to ensure that they meet regulation standards with specialized road testing equipment.

Multiple Testing Equipments

Regular analysis of the work completed is checked using road testing equipment, and the readouts are then handed over to the supervisors, who will confirm that they meet the set regulations. Some of the equipment used to do this is the light weight deflectometer, falling weight deflectometer, ground penetrating radar equipment, special core drills, etc.

Road Construction

The light weight deflectometer is a portable impulse plate load tester for determining the compaction quality and load bearing capacity of soils and non-cohesive sub-bases.Useful in all types of earth works and ground engineering applications, by determining the dynamic deformation modulus.

Road Maintenance

Another useful equipment for autonomous evaluation of runway conditions with data output provided in standard excel sheets is the falling weight deflectometer. Highly recommended for  highways, local roads, airport pavements, and railway tracks .The FWD is useful for determining the approximate remaining available pavement life before rehabilitation will be required.An impulse plate load is employed simulating traffic loads to the pavement surface and geophone sensors are utilized to record the vertical deflection shape response of the pavement.The data is put in the back calculation software which is then used for determining elastic moduli of pavement layers.
