LCB-2 Type Field CBR Tester

This instrument is designed and manufactured in accordance with JTJ 059‑95, the “Field Test Procedure for Highway Subgrade and Pavement,” and is suitable for determining the in‑situ CBR value of various subgrade materials on highway construction sites. Its operating principle involves using a heavy‑duty vehicle with a rear axle load of at least 60 kN, applying incremental loads via a jack, and calculating the in‑situ CBR value based on the penetration depth measured by the penetration rod and the applied load determined by the load cell.

Description

Product Introduction:

This instrument is designed and manufactured in accordance with JTJ 059‑95, “Field Test Procedures for Highway Subgrade and Pavement,” and is suitable for determining the in‑situ CBR values of various subgrade materials on highway construction sites.

The principle of the test is to use a heavy-duty truck with a rear axle load of at least 60 kN, apply additional load using a jack, and determine the in‑situ CBR value of the subgrade by measuring the penetration depth with a penetrometer rod and the applied load with a load cell.

Technical Specifications:

Hydraulic jack	100 kN and ball seat
Dynamometer	60KN
Penetration rod	Diameter Φ50mm, length 200mm
Load-bearing plate	1.25 kg per piece, 4 pieces
Penetration Measurement Device	Platform and dial indicator
