Applications of Light Weight Deflectometer on the Construction Site
Posted by Frank Georg Schulz on September 23rd, 2015
The light weight deflectometer is the (1) more compact and (2) portable version of the falling weight deflectometer. These features make LWDs ideal in construction sites. Light weight deflectometers are reliable when you need to verify the quality of natural soil before construction begins. The portability enables you to bring the device anywhere on the site without the need for a loading vehicle. This way, you can conduct tests faster at no additional cost.
Light weight deflectometers are suitable for construction sites that have hard to reach places. It can be difficult to test areas like backfills and ditches when you have a bulky falling weight deflectometer, but an LWD eliminates that problem and will enable you to complete the testing in no time. Both cabled and wireless LWD units have a weatherproof box with an external control panel. The GPS system with built-in screen display provides more accurate data.
Some LWDs are cable-free and can transfer data into your smartphone or tablet via Bluetooth. The wireless data transfer is ideal for construction sites because it eliminates the need to have a measuring computer exposed to the harshest conditions, and no wire can get in the way and slow down your progress. Wireless LWDs are more durable and ideal for the toughest conditions in construction sites due to the absence of its 'Achilles' heel', which is the load plate socket. Without the cable, there should be no problem and you can avoid having to cancel or delay your projects because the testing device must be repaired.
You can print results on site using the integrated printer in LWDs. This way, you do not have to wait to get back to your lab to review the results and you can increase productivity in the workplace. LWDs are designed to work with special software to help you analyze, manage and evaluate data. All LWD models have a USB drive for easy data transfer to your PC, too. The high-performance battery is reliable and rechargeable to help you save money in the long run.
LWDs are versatile for a wide range of construction projects. They are compliant with international and German regulations for light weight deflectometers. TP BF-StB part B 8.3 edition 2012 is the German regulation that ensures the suitability of an LWD for rock and soil in road construction. ZTV E-StB 09 is a German regulation that provides the additional terms of rules and contract for earthwork in a construction of roads.
