How to Measure Hot Mix Asphalt Temperature with Myzox AST-10 Malaysia
How to Measure Hot Mix Asphalt Temperature with Myzox AST-10 Malaysia
Accurate temperature measurement is an important part of hot mix asphalt paving and road construction quality control. Contractors need to know the actual asphalt temperature during delivery, placement and compaction instead of relying only on visual observation or elapsed time.
The Myzox AST-10 Digital Asphalt Thermometer is designed for pavement temperature control and can be used with a penetration probe for asphalt temperature measurement.
This guide explains how the Myzox AST-10 can be used for hot mix asphalt temperature checking during road construction projects in Malaysia.
What Is the Myzox AST-10?
The Myzox AST-10 is a portable digital thermometer compatible with Type-K thermocouple probes.
The main instrument supports a wide Type-K measurement range of:
-200掳C to +1,370掳C
The actual usable temperature range depends on the connected probe.
For asphalt applications, the AST-10 is supplied with the Myzox SE-IN needle probe.
The SE-IN probe offers:
200 mm probe length
Penetration-type measurement
Measurement range from -50掳C to +650掳C
Suitability for asphalt measurement
This makes the combination useful for road paving and asphalt quality-control applications.
How Do You Measure Hot Mix Asphalt Temperature?
A typical asphalt temperature measurement procedure involves inserting a suitable temperature probe into the asphalt material and allowing the reading to stabilize.
Always follow the project's approved testing procedure, safety requirements and applicable specifications.
Step 1: Prepare the Myzox AST-10
Before starting work, check that the thermometer and probe are in suitable condition.
Ensure that the Type-K thermocouple probe is properly connected to the AST-10.
Check the display and battery condition before taking measurements.
Step 2: Select an Appropriate Measurement Location
Choose the measurement location according to the project's quality-control procedure.
Temperature may be checked at different stages, including:
Hot mix asphalt delivery
Asphalt before placement
Material behind the paver
Freshly placed asphalt
Before rolling
During compaction
Pavement repair works
Avoid assuming that one temperature reading represents the entire paving area.
Step 3: Insert the SE-IN Probe into the Asphalt
The Myzox SE-IN is a 200 mm needle-type penetration probe.
Carefully insert the probe into the asphalt at the required measurement location.
Penetration measurement allows the sensor to measure temperature within the asphalt material rather than only the exposed surface.
This is particularly useful because the surface and internal material may cool at different rates.
Step 4: Allow the Reading to Stabilize
Do not immediately remove the probe after insertion.
Allow sufficient time for the displayed temperature to stabilize.
Once the reading becomes stable, record the temperature according to the project's inspection or quality-control procedure.
The AST-10 also provides a Data Hold function, which can make it easier to retain a displayed value when working on site.
Step 5: Repeat Measurements Where Required
Road paving involves a large volume of material spread across a considerable area.
For this reason, multiple temperature measurements may be required according to the project specification or quality-control plan.
Possible measurement points include different:
Truck loads
Paving locations
Sections of road
Times during placement
Compaction stages
Repeated measurements provide more useful information than relying on a single reading.
Why Measure Inside the Asphalt?
The temperature at the pavement surface does not necessarily represent the temperature deeper inside the asphalt layer.
Surface temperature can be influenced by:
Wind
Ambient temperature
Rain
Direct exposure to air
Existing pavement temperature
Asphalt thickness
Time after placement
A penetration probe allows temperature measurement within the material.
This is one reason the 200 mm Myzox SE-IN probe is particularly useful for asphalt applications.
Can the AST-10 Measure Asphalt Surface Temperature?
The AST-10 can also be paired with the optional Myzox SE-SU surface probe.
The SE-SU measurement range is:
-20掳C to +400掳C
This provides another measurement option when contact surface temperature measurement is required.
For penetration into asphalt, however, the SE-IN needle probe is the more relevant accessory.
What Is the Measurement Range of the Myzox AST-10?
The AST-10 main instrument supports Type-K thermocouple measurements from:
-200掳C to +1,370掳C
However, users should always consider the operating range of the connected probe.
For example:
SE-IN Needle Probe:
-50掳C to +650掳C
SE-WI Wire Probe:
-30掳C to +200掳C
SE-SU Surface Probe (Optional):
-20掳C to +400掳C
The correct probe should therefore be selected according to the measurement application and expected temperature.
Useful AST-10 Functions for Asphalt Inspection
The Myzox AST-10 provides several useful functions for field temperature measurements, including:
MAX measurement
MIN measurement
Data Hold
Relative measurement mode
Type-K thermocouple compatibility
These features make the instrument suitable for repeated measurements during construction and inspection work.
When Should Asphalt Temperature Be Checked?
Depending on the project requirements, asphalt temperature measurement may be performed during several stages of the paving process.
During Delivery
Checking the temperature when hot mix asphalt arrives at site can help contractors monitor material condition after transportation.
During Placement
Measurements during paving provide information about the temperature of the material being placed.
Before Compaction
Temperature information can assist the site team in managing the compaction process according to the project's requirements.
During Road Maintenance
The same measurement principle can be applied to asphalt resurfacing, patching and pavement repair operations.
Common Asphalt Temperature Measurement Mistakes
Some common mistakes to avoid include:
Measuring only one location
Removing the probe before the reading stabilizes
Using a probe outside its specified temperature range
Assuming surface and internal temperatures are identical
Using damaged thermocouple probes
Failing to record measurement locations
Relying only on visual estimation
Ignoring project-specific testing procedures
A good thermometer is only one part of reliable temperature measurement. Consistent measurement technique is equally important.
Who Should Use the Myzox AST-10?
The Myzox AST-10 is suitable for professionals involved in:
Road construction
Highway projects
Asphalt paving
Pavement resurfacing
Road rehabilitation
Civil engineering
Infrastructure projects
Asphalt quality control
Construction inspection
Road maintenance
It can be particularly useful for contractors, site engineers, supervisors, technicians and quality-control personnel who need a portable asphalt temperature measurement instrument.
Is the Myzox AST-10 Suitable for Road Construction in Malaysia?
Yes. The AST-10 is designed for pavement temperature control, while its SE-IN 200 mm needle probe is suitable for asphalt measurement.
This makes it a practical temperature measurement solution for Malaysian road construction, highway, pavement rehabilitation and asphalt maintenance projects.
