Roll pressure machine and density estimation system of asphalt mixture

摘要

Problem to be solved: to provide a density estimation method of a asphalt mixture capable of estimating the density of asphalt mixture forming a road with a small workload, a pressure estimating machine, and a density estimation system for asphalt mixture.The pressure roller 10 isAttached to the rolling body 1The density estimating device 11 is provided for estimating the density of the asphalt mixture a on the road surfaceDensity estimation device 11 isA transmission part 3a for transmitting electromagnetic wave W1 toward road surfaceThe receiver 3B receives the reflected wave W2 of the electromagnetic wave W1 reflected from the road surfaceBased on reflected wave information indicating the characteristics of reflected waveAn arithmetic unit 4 for estimating the density of asphalt mixture on road surface 30 is provided.Diagram
