技术数据：
了解热拌沥青混凝土（HMA）重量、体积、体比重的相互关系。对混合设计与结构两者是很重要的。根本上说，混合设计的目的是确定沥青胶结料的体积和所需的骨料，而生产所期望特性的混凝土。
测量压实沥青混凝土的体比重（Gmb）尽可能准确是非常重要的，因为量测值是用来转换实际的重量与体积重要的依据，任何在压实沥青混合物体比重（Gmb）的微小错误，将造成实际体积值的错误。
体比重是热拌沥青混凝土（HMA）一个重要依据，因为它被用于计算其它热拌沥青混合料（HMA）添加量与孔隙率的计算。
沥青混凝土标准密度，以沥青拌和厂取样试验的马歇尔密度或试验段密度为准。
沥青混凝土密度试验时应根据混合料本身的特点，可采用下列方法之一：
A：试件的吸水率小于2％时：表干法
B：试件的吸水率大于2％时：水中称重法、封蜡法。
C：空隙率较大的沥青碎石混合料及大空隙透水性开级配沥青混凝土试件：体积法。

MH-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 b,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) accuraby is very important as far as possible, because the measuring value is according tothe weight and volume conversion practical important,any of the compb of asphalt mixture proportion(Gmb) b 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 bs:
A: specimen bibulous rate is less than 2%: surface dry
B: specimen bibulous rate is greater than 2%: underwater weighing, sealing wax.
C: void frb of open graded asphalt concrete specimens of asphalt macadam mixture and porouspermeable larger: Volume b.
