MH-600B數字瀝青混凝土比重計Hydrometer
原理：根據ASTM D 6752、C 127、D8、D70、AASHTO T 166、AASHTOMH-600B digital asphalt concrete gravity meterHydrometer
Principle: according to the ASTM D 6752, C 127, D8,D70, T 166, AASHTO AASHTO
T 22 the Archimedes principle of water buoyancy method,accurate, fast, direct measuring values.
Technical data:
Understanding of hot mix asphalt concrete (HMA)relationship between weight, volume, body weight. Is very important for the mixture of both design and structure.Basically, the mixed design to determine asphalt binderand aggregate volume required, and the production of the desired characteristics of concrete.
Measurement of body density of compacted asphalt concrete (Gmb) accurately is very important as far as possible, because the measuring value is according tothe weight and volume conversion practical important,any of the compaction of asphalt mixture proportion(Gmb) object a slight error, will cause the error of the actual volume value.
Body proportion is the hot mix asphalt concrete (HMA) is an important basis, as it is used to calculate the mixture of other hot mix asphalt (HMA) calculation amount and porosity.
Asphalt concrete density, with asphalt mixing plantsampling test Marshall density or test section densityshall prevail.
Asphalt concrete density test should be based on themixture itself characteristic, can use one of the following methods:
A: specimen bibulous rate is less than 2%: surface dry
B: specimen bibulous rate is greater than 2%: underwater weighing, sealing wax.
C: void fraction of open graded asphalt concrete specimens of asphalt macadam mixture and porouspermeable larger: Volume method.
