The RoadReader 3450 Thin-Layer & Full Depth Density Gauge is the most versatile moisture density gauge ever produced. It combines the measurement modes proven in thousands of Troxler 3400 series gauges with a patented method for true thin-layer asphalt and concrete bridge deck overlay density measurement.
By combining thin-layer and full depth measuring capabilities in one instrument, the RoadReader 3450 is our flagship gauge in the 3400 series. With its versatility, speed, and economy, the RoadReader Plus is designed to satisfy your compaction control needs at every stage of your project.
Like all 3400 series gauges, the Model 3450 meets ASTM Standard Test Methods D-6938 (replaced ASTM D-2922 and ASTM D-3017 as of November 2006), D-2950, C-1040 and AASHTO T-310.
