When, make the device can be used for testing by adjusting supporting construction 2.
Asphalt foaming performance test experiment is general to use standard drum access foamed asphalt, uses the measurement mark matched with it
Chi.The relation of surveyors' staff and bucket size is determined with water gauge：
Standard drum add water after gross mass：M1=ρ V1+ M=ρ SH1+M
The quality added water：Δ M=M1- M=ρ SH1
500g asphalt qualities：Ma=ρa·S·H
The corresponding height of 500g pitches：
In formula, M is the quality of empty barrel, g；ρ is the density of water, kg/m3；S is the cross-sectional area of standard cylinder, m2；MaFor
500g asphalt qualities；ρaFor asphalt density, kg/m3；H1To add the height of standard drum reclaimed water, mm；H is 500g pitches in standard
Height in bucket, i.e., the corresponding height of one expansion rate, mm.
As the above analysis, three parameter (H need to be only surveyed with such a method1, M1, M) and it is that can determine that access foamed asphalt
Bucket and the corresponding relation between surveyors' staff, Measurement scales.For standard drum, the corresponding height of an expansion rate is 8.9mm.
Vernier height gauge pointer is moved up to nH distance, n can be arbitrary constant, rotary motion body 3 according to demand
The pendant lower surface of the first rotating disk 32 is alignd with vernier height gauge pointer, scale is drawn in the position of reading line projection to side plate 23
The expansion rate graduation mark of line, according to this method drafting foaming effect test device.
Calculated according to perfect condition and the actual foam performance of existing foam device, maximum swelling rate has limiting value, phase
Rope length degree, each disk diameter answered have preferred scope.Because expansion rate graduation mark is to be plotted in the first rotating disk 32, the second rotating disk 33
Project to the circular scale line of side plate 23, to avoid the occurrence of the overlapping of scale, turntable rotation no more than one week to be advisable, i.e. rotating disk
Maximum swelling rate can be measured before being rotated by 360 °；Circumference is evenly distributed in make scale try one's best, rotating disk is being measured most
Turning over angle during big expansion rate also should not be too small.The arbitrfary point on H and the circumference of the first rotating disk 32 that pendant is moved straight up
Rotation distance L is equal, therefore the diameter D angle, θ relations that turn over corresponding with maximum swelling rate of traffic cycle are：
Hmax=L
In formula, HmaxPendant vertically movable distance during for maximum swelling rate.According to HmaxScope, it may be determined that suitable rope
Length, according to HmaxThe suitable diameter range of the first rotating disk 32 can be determined with angle, θ scope, corresponding second rotating disk 33 is a diameter of
The diameter 1/2 of first rotating disk 32.
Draw after pitch expansion rate graduation mark, specific testing process is as follows：The mobile measurement apparatus makes at pendant
Above standard volume barrel side, adjustment measurement apparatus makes it be unlikely to influence the injection of pitch, and pendant is avoided the foam sprayed
Pitch.Cross-line is set to be alignd with the zero line of graduation mark, adjustment rotating shaft 31 makes pendant lower surface concordant with standard cylinder bucket bottom.Carry out
Before pitch injection, rotatable rotor 3 makes pendant rise to foamed asphalt liquid level desired location.After pitch injection, foamed asphalt liquid
Face is gradually increased to peak, and rapid fine-adjustment rotary body 3 makes the pendant lower surface of the first rotating disk 32 and foamed asphalt liquid level peak neat
It is flat, stopwatch is pressed, keeps rotational body position motionless, cross-line corresponding scale on side plate 23 is read, this reading is foam
Pitch maximum swelling rate.Because circular diameter where the second rotating disk 33V type grooves bottom surface only has the half of the first rotating disk 32, when first turn
When disk 32, the second rotating disk 33 make concentric rotational movement, the pendant lifting height of the second rotating disk 33 only has the rising of the pendant of the first rotating disk 32
The half of height, i.e., when the pendant lower surface of the first rotating disk 32 rises to liquid level peak, the pendant lower surface of the second rotating disk 33 rises to
The position of maximum swelling rate respective heights half.Asphalt foam is gradually vanished, and its liquid level is gradually reduced by peak, until second
When the pendant lower surface of rotating disk 33 is exposed, stopwatch is pressed again, and stop watch figures are the half-life period of correspondence foamed asphalt, and test terminates.
The asphalt foaming measurement of effectiveness device that above-mentioned technical proposal is provided, using Concentric rotation rotating disk its angular speed it is equal,
The principle that linear velocity is directly proportional to diameter, by foamed asphalt liquid level peak position in foamed asphalt foaming effect measurement process with
The position of one half is indicated with marker respectively, reduces the influence that human factor reads the moment to half-life period and judged；Expansion rate
The traditional measurement scale for eliminating the reliance on that minimum scale is 6 is read, can be read directly from graduation mark, measurement accuracy is greatly increased.
Another embodiment of the utility model provides a kind of asphalt foaming measurement of effectiveness method, can be above-mentioned using the utility model
The asphalt foaming measurement of effectiveness device that embodiment is provided is realized.This method specifically includes following steps：
Step S10, drafting expansion rate graduation mark.Drafting zero line, maximum limit and lattice scale are specifically included, point
Lattice scale can be set must be than comparatively dense, to realize the measurement of high accuracy.
Corresponding position is determined when zero point line is located at measurement bottom of the barrel according to contact site bottom.Maximum limit is according to calculating
The corresponding position of theoretical maximum expansion height is obtained to determine.Lattice is then to divide equally the span between zero point and greatest limit.
The expansion rate graduation mark is used to read expansion rate in test process.Specifically, above-mentioned step S10 can include
Following two steps：
Step 1: determining the zero point of expansion rate graduation mark so that the of the zero point correspondence contact component of expansion rate graduation mark
One contact site and the second contact site contact the position of empty barrel bottom surface simultaneously.
Step 2: calculating the preferable maximum for obtaining expansion rate, expansion rate graduation mark range is determined according to experimental configuration
Maximum.
After step S20, foamed asphalt are ejected to from asphalt foaming apparatus in measurement bucket, will and the first contact site be moved
Move to the first contact site bottom surface and contact the peak of pitch liquid level after foaming, it is corresponding when reading the first contact site in the position
Expansion rate and the start time T0 of half-life period.According to the corresponding position of cross-line on rotating disk, pitch expansion rate is directly read.
Step S30, wait pitch decay, until the second contact site exposes and the second contact site bottom surface and pitch liquid level
Concordantly, the end time T1 of half-life period is recorded；
Step S40, calculating T1 and T0 difference obtain half-life period.
Above-mentioned technical proposal, foamed asphalt liquid level peak and one half height position are indicated respectively by two markers
Put, two markers are synchronized with the movement, wherein a marker indicates liquid level peak, correspondence expansion rate, one other identification thing indicator solution
Face peak half height and position, exposes time interval for half-life period from liquid level peak to one half height position.It can be seen that, on
Technical scheme is stated, by setting marker, expansion rate and the half-life period of asphalt foaming can be accurately measured, and it is workable.
