Overview

I. Functional Introduction:

The asphalt nuclear-free density gauge can quickly detect the density, porosity, and compaction of asphalt mixtures on road surfaces and asphalt core walls of hydraulic dams. It uses electromagnetic induction technology instead of nuclear source radiation methods, which reduces costs, enhances safety, and eliminates concerns over complex environmental impact assessments, time-consuming training, and stringent transportation regulations. Calibration is simple, precision is high, repeatability is good, and touchscreen operation allows users to complete relevant operational training and master field quality inspection techniques within a short period of time.
