Product Description
Pavement physical properties evaluating machine FWD falling weight deflectometer
A falling weight deflectometer (FWD) is a testing device used by civil engineers to evaluate the physical properties of pavement . FWD data is primarily used to estimate pavement structural capacity for 1) overlay design and 2) to determine if a pavement is being overloaded. Use includes (but is not limited to) highways, local roads, airport pavements, harbor areas and railway tracks. The machine is usually contained within a trailer that can be towed to a location by another vehicle. It can also be built on a pickup truck, inside a mini van or on a heavy truck together with a TMA protection.
FWD makes it possible to treat pavement structures in the same manner as other civil engineering structures by using mechanistically based design methods. Selecting the type of rehabilitation to be implemented on a given pavement is of considerable economic significance. To reach that decision without an adequate knowledge of the structural condition of the pavement may have very costly consequences. The use of a FWD enables the engineer to determine a deflection basin caused by a controlled load with accuracy and resolution superior to other existing test methods. The FWD produces a dynamic impulse load that simulates a moving wheel load, rather than a static, semi-static or vibratory load. These developments allow the use of mechanistic approaches to analyse FWD data.
Features
• Several models for different applications
• Easy to operate, and fully-automatic
• "One-Key Operation"
The whole testing task can be completed by one single person with pressing just one key. That means the driver himself can finish the task if the "Start" key is located beside him. The testing task can also be started by PC.
• Fast measurement
≤20s/point, and can be reduced to ≤10s/point if fast measurement software applied.
• Multi-functional and Professional
• Strong and durable trailer base plate, imported from Germany
• Equipped with laptop for wireless data transmission
• GPS location and temperature measurement
• Auto capture of deflection value and load value.
• Continuous outdoor working.
• Storage Battery Charging
charging by electric generator on the tractor or 220 V electricity supply
• Double Locking System: Hydraulic/ Mechanical
• Emergency System: Lift the load plate when system breaks down.
• Operation Options: Manual/ Automatic
• Working status of load plate can be monitored on the screen.
• Inertia Braking
Synchronized turn/break/back light and head warning light with the tractor Powerful Software
