Hot coefficient testing device assembles complete diagram.
Using the device that installation is complete measure the rate of heat transfer of different-thickness heated bitumen slurries and cement concrete top plate with
Heat transfer coefficient, technology path is as shown in Fig. 2, testing procedure is as follows：
(1) experiment prepares, and includes mainly equipment prepares, pitch prepares, Sorbet prepares etc..In the equipment preparation stage, cloth is needed
If good equipment each section, whether detection temperature sensor works normally with moisture recorder, and ensures that testing required tool arrives
Position；Ice cube is stored using foam insulation box, blocky ice is ground into before each experiment it is sand-like, as experiment Sorbet；It is testing
Preceding preparation slip casting pitch.
(2) Sorbet merging, compacting, leveling, temperature control.It, need to be to drop to ensure that the cooling-down effect for testing cooling slot every time is identical
Sorbet quality, temperature and surface smoothness carry out quantitative control in warm slot.Each electronic scale weighs the single drop of Sorbet 26g mergings
In warm slot, Sorbet in cooling slot is compacted and is flattened to cooling slot cornice flush.Using infrared temperature-measuring gun to ice in cooling holes
Carrying out temperature monitoring can be tested when temperature is at -0.5~0 DEG C.

Native top plate carries out a thermometric, and whether judgement cement concrete top plate is in test determination temperature range.
(6) after the test, test data is exported by moisture recorder, and carries out the processing of test data.
Since adiabatic pedestal is only the dissipation of dramatically reduction heat, and it is non-fully adiabatic, to improve test data
Precision need carry out systematic error eliminate experiment, keep experimental condition it is constant in the case of, cement concrete top plate is changed to
The adiabatic top plate of identical initial temperature, record pitch slurries temperature damping's rule under conditions of being up and down heat-insulating shield, then by the examination
It tests the test data that data are obtained with Fig. 2 technology paths to be handled, obtains heated bitumen slurries-coagulating cement under different-thickness
The rate of heat transfer of native plate.Testing procedure in addition to above-mentioned cement concrete top plate is changed to adiabatic top plate, remaining testing procedure with it is upper
State that testing procedure is identical, the technology path that systematic error eliminates experiment is as shown in Figure 3.

Slurry temperature change curve when showing capping cement concrete slab in height 1mm Asphalt tanks, i.e. asphalt temperature are at any time
Increase and constantly declines；Slurry temperature change curve when similarly obtaining being capped adiabatic top plate in height 1mm Asphalt tanks, such as Fig. 4
(b) shown in.
When pitch-cement concrete slab temperature difference is Δ T, the calculation formula of pitch rate of heat transfer isCause
This carries out derivation to the curve in above-mentioned Fig. 4 (a) and Fig. 4 (b) respectively, multiplied by with specific heat capacity c, asphalt density ρ and pitch thickness
B, pitch rate of heat transfer when adiabatic with the capping top plate of pitch rate of heat transfer when obtaining capping cement plate, only due to adiabatic pedestal
Dramatically to reduce heat loss, not can be completely adiabatic, to improve the precision of test data, it is necessary to systematic error into
Row is eliminated, i.e., subtracts each other the two, the true rate of heat transfer v of t moment pitch can be obtainedQ(t), and because of asphalt temperature T and time t
For one-to-one relationship, therefore when can derive that the temperature difference is Δ T, pitch rate of heat transfer v under unit areaQ(Δ T), such as Fig. 4 (c)
It is shown.It is by the heat transfer coefficient of pitch againWhen can derive that the temperature difference is Δ T, the heat transfer coefficient h of pitch, such as Fig. 4
(d) shown in.
By Fig. 4 (c) it is found that when pitch slot thickness is 1mm, with the increase of the temperature difference, pitch-cement concrete slab heat transfer
Rate significantly increases, and the two is substantially in a linear relationship.By Fig. 4 (d) it is found that heat transfer coefficient is constantly fluctuated with difference variation, numerical value
In 48~50.5J/m2Between s DEG C, maximum changing amplitude 4.8% has higher stability.In view of experiment misses
The presence of difference, it is believed that heat transfer coefficient remains constant, and pitch-cement concrete heat transfer coefficient is under 1mm thickness
49.6J/m2·s·℃。
