Summary

    SYD-0705 compacted bituminous mixtures density tester is designed and made as per T0705-2011 “Compacted Bituminous Mixtures Density Test (Surface Drying Method)” in the Industry Standard of People’s Republic of China JTG E20-2011 Standard Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering. Meanwhile it gives consideration to T0706-2011 “Test Method for Compacted Bituminous Mixtures Density (Water Weight Method)” and T 0707-2011 “Test Method for Compacted Bituminous Mixtures Density (Wax Sealing Method )” .

The instrument is suitable to:

1.The instrument is suitable to determine the bulk volume relative density and the bulk volume density of the water
   absorption that is less than 2% for kinds of bituminous mixtures specimen by the surface drying method as per T0705
   standard.

2.The instrument is suitable to determine the apparent relative density and the apparent density of the water absorption
   that is less than 0.5% for the compacted bituminous mixtures specimen by the water weight method as per T0706
   standard.

3.The instrument is suitable to determine the bulk volume relative density and bulk volume density of the water
   absorption that is more than absorption that is more than 2% for the bitumen concrete or bituminous mixtures specimen
   by the wax sealing method as per T0707 standard.   

4.The instrument is equipped with the balance; it can be used to weigh the air quality of the dried specimen as per T0708
   standard, and then calculate the bulk volume relative density and bulk volume density of the specimen by the
   volumetric method.
