Asphalt Temperature Measurement for Highway Resurfacing with Myzox AST-10 Malaysia
Asphalt Temperature Measurement for Highway Resurfacing with Myzox AST-10 Malaysia
Highway resurfacing requires careful coordination between pavement preparation, asphalt delivery, paving and compaction. Because hot mix asphalt continuously loses heat throughout these operations, temperature measurement can form an important part of the project's QA/QC process.
The Myzox AST-10 Digital Asphalt Thermometer, used with the SE-IN 200 mm needle probe, provides highway contractors, site engineers and QA/QC teams with a practical solution for penetration temperature measurement during asphalt resurfacing and pavement rehabilitation works in Malaysia.
Why Is Temperature Measurement Important During Highway Resurfacing?
Highway resurfacing operations often work within limited construction windows.
Contractors may need to coordinate:
Lane closures
Traffic management
Milling
Surface preparation
Asphalt deliveries
Paving
Rolling
Reopening of the road
Any delay in this sequence can affect the timing of asphalt placement and compaction.
Actual temperature measurement provides useful information about the asphalt condition at specific stages of the operation.
Typical Highway Resurfacing Workflow
A resurfacing project may involve:
Existing Pavement → Milling → Surface Preparation → Asphalt Delivery → Paving → Temperature Measurement → Compaction → Inspection
The exact construction sequence varies according to the project.
Temperature checks can be incorporated at appropriate stages according to the approved method statement and QA/QC plan.
Asphalt Temperature at Delivery
Hot mix asphalt may travel from the production plant to the highway work zone.
Transportation conditions can include:
Long travel distance
Traffic congestion
Waiting at site
Lane closure timing
Weather changes
Paving delays
By measuring asphalt temperature when the material arrives, contractors obtain an actual reading after transportation.
Temperature Behind the Paver
Freshly laid asphalt begins cooling immediately.
Where required, temperature can be checked at selected locations behind the paver.
Recording the measurement location and time helps provide context for each reading.
Temperature Before Compaction
Rolling and compaction must be carried out according to the asphalt mix and project requirements.
A temperature measurement before compaction provides numerical information about the material at that stage.
The AST-10 measures temperature but does not determine the correct compaction temperature.
The required criteria should always come from the applicable project documentation.
Temperature During Compaction
Additional measurements may be taken during rolling where required.
This allows the QA/QC team to observe temperature changes as the asphalt continues to cool.
Multiple readings can be particularly useful when resurfacing long highway sections.
Myzox AST-10 for Highway Works
The Myzox AST-10 is designed for pavement temperature control.
It supports Type-K thermocouple probes with a main instrument measurement range of:
-200°C to +1,370°C
The actual usable range depends on the connected probe.
For asphalt penetration measurement, Myzox offers the SE-IN Needle Probe.
SE-IN 200 mm Penetration Probe
Key SE-IN specifications include:
Probe length: 200 mm
Measurement range: -50°C to +650°C
Probe type: Penetration needle thermocouple
Myzox identifies the SE-IN as suitable for asphalt measurement.
This allows direct contact temperature measurement within the asphalt material.
Why Penetration Temperature Measurement?
The exposed pavement surface is directly affected by environmental conditions.
These can include:
Wind
Ambient temperature
Rain
Moisture
Time after paving
Material below the surface may retain heat differently.
For this reason, a surface temperature measurement and penetration temperature measurement should not automatically be considered equivalent.
AST-10 vs Infrared Thermometer for Highway Resurfacing
An infrared thermometer generally measures the exposed pavement surface.
The AST-10 with SE-IN probe measures temperature by penetration into the asphalt.
An infrared thermometer may be convenient for quick surface scanning, while a penetration thermocouple provides direct contact measurement within the material.
The correct measurement method should follow the project requirements.
Night Highway Resurfacing
Many highway resurfacing projects are carried out at night to reduce traffic disruption.
Night work can involve:
Different ambient temperatures
Changing wind conditions
Limited working periods
Traffic management constraints
Tight paving schedules
Actual asphalt temperature measurements can provide useful information throughout these operations.
Temperature Monitoring After Delays
Highway works can experience unexpected interruptions caused by:
Traffic incidents
Equipment problems
Rain
Asphalt delivery delays
Paver stoppages
During these interruptions, asphalt continues changing temperature.
Where relevant, contractors can take an updated measurement before operations continue.
Data Hold for Active Work Zones
The AST-10 includes a Data Hold function.
Once a stable temperature is obtained, the displayed value can be retained.
This can make it easier for technicians to record the result after moving to a safer position away from active paving equipment.
MAX and MIN Functions
The AST-10 also provides:
MAX measurement
MIN measurement
Relative measurement mode
These functions provide additional flexibility for repeated field measurements.
Can AST-10 Measure Pavement Surface Temperature?
Yes, with the optional Myzox SE-SU Surface Probe.
The SE-SU has a specified measurement range of:
-20°C to +400°C
This provides contact surface temperature measurement.
For asphalt penetration measurements, the SE-IN needle probe is the more relevant choice.
Highway Resurfacing QA/QC Records
Temperature readings can be documented together with:
Highway or project name
Date
Time
Lane
Chainage
Asphalt mix
Truck number
Batch
Measurement stage
Temperature
Weather
Inspector
Remarks
This creates traceable information across long resurfacing sections.
Suitable Applications
The AST-10 can be considered for:
Highway resurfacing
Expressway maintenance
Asphalt overlay
Pavement rehabilitation
Lane repair
Interchange resurfacing
Toll plaza pavement works
Road widening
Highway patching
Preventive maintenance projects
FAQ: Is Myzox AST-10 Suitable for Highway Resurfacing?
Yes.
The AST-10 is designed for pavement temperature control, and its SE-IN 200 mm needle probe is suitable for asphalt measurement.
It can therefore be considered for temperature monitoring during highway resurfacing where penetration measurement is required.
FAQ: Can AST-10 Be Used During Night Highway Work?
Yes.
It can be used during night paving and resurfacing operations, subject to proper site lighting, work-zone safety and approved measurement procedures.
FAQ: Can AST-10 Measure Temperature Before Rolling?
Yes.
The SE-IN probe can be used for penetration temperature measurement before compaction where required by the project procedure.
FAQ: Does AST-10 Determine Whether Asphalt Can Be Compacted?
No.
The instrument provides the temperature reading.
The responsible engineering personnel should interpret that reading according to the asphalt mix requirements and applicable project specification.
Asphalt Thermometer for Highway Contractors Malaysia
Highway resurfacing involves more than simply placing a new asphalt layer.
Transportation, traffic management, paving timing, environmental conditions and compaction all need to be coordinated.
Temperature measurement gives contractors numerical information that can support this process.
The Myzox AST-10 Digital Asphalt Thermometer with SE-IN 200 mm penetration probe provides a practical field solution for asphalt temperature monitoring during highway resurfacing and pavement rehabilitation projects in Malaysia.
