Product Overview

The EVD dynamic deformation modulus tester, also known as light weight falling weight deflectometer, is a portable rapid soil subgrade testing instrument. It simulates vehicle dynamic load through free falling hammer impact, automatically calculates soil dynamic deformation modulus Evd value, to evaluate subgrade bearing capacity and compaction quality. It complies with German TP BF-StB Part B8.3 and China railway TB10102 standards, widely adopted for highway, railway, municipal engineering, airport and building foundation construction quality inspection.

Core Product Advantages

  1. Fast Dynamic Impact Test, High EfficiencyNo long static load holding required, single test finished within 30 seconds, greatly improve field construction acceptance speed, ideal for large-scale road subgrade batch inspection.

  2. Standard Standardized Loading Structure10kg free fall hammer, 700±20mm fixed drop height, maximum impact force 7070N, impact duration 18±1ms; 300mm diameter 15kg thickened bearing plate, consistent test conditions to guarantee data repeatability.

  3. Intelligent Digital Handheld Host3.5-inch touch screen with Chinese & English bilingual display, automatically calculate Evd modulus, settlement deformation and test curve; built-in large memory to save 2000 groups of test data. Support Bluetooth thermal printer for on-site report output, USB data transmission to PC for analysis & archiving.

  4. Long Endurance Outdoor BatteryBuilt-in rechargeable lithium battery, continuous working time over 9 hours, adapt to all-day outdoor construction site operation without frequent power charging.

  5. Durable Anti-Corrosion Metal AssemblyLoading rod and bearing plate adopt thick stainless steel nickel plating treatment, anti-rust, anti-impact and anti-deformation, suitable for dusty, muddy construction environment. Test effective influence depth reaches 0~500mm, accurately reflect subgrade filling layer bearing performance.

  6. Wide Industry Compliance & ApplicationMeet domestic and international road construction test standards, applicable to various particle size soil, gravel mixed filler, subgrade backfill, road base layer compaction detection.
