Detailed Description

Suitable For：Construction, Geological Exploration, Research on Roadway Principle：In accordance with ASTM D 6752,C 127,D8,D70,AASHTO T 166,T 22. Adopt the buoyancy method of Archimedean principle, can measure the density accurately and fast. Technical data ＊In the field of composite design and for component structure, it's vitally important to understand the mutual relationship among HMA's weight, volume and bulk density. Basically, the aim of composite design is to judge HMA’s volume and its skeletal materials. To measure the bulk density of HMA as accurately as possible is important, because its value is the main foundation when transforming the real weight and volume. Any tiny mistake may cause fatal problem to real volume value. The bulk density is an important factor of HMA because its value is used for calculating on HMA’s addition and porosity. Measuring the density of HMA should notice the features of the composite materials, there are several methods recommended: A: when sample's water absorbing capacity <2%: surface saturated density B: when sample's water absorbing capacity >2%: weighing in liquid/ sealing wax method C: as to asphalt macadam mixture with big void or permeable HMA with big void: use volume method Functions and Features 1. Can show Bulk density, Apparent porosity, Wet density, Volume of Compacted asphalt concrete . 2. Only 10 seconds to show the testing result.
