Asphalt paving installation in colder weather is okay.
The simple question has a quite complicated answer. In fact, the asphalt contractor remains with a thermometer hanging to figure out if the temperature is operational.
Or, is it too cold to pave?
In cold weather, achieving mixed temperatures for ideal compaction is challenging. The step compaction needs to be finished in lesser time. Obviously, due to the cold temperature, the mix will cool fast.
Understanding the key factors determining the cooling rate of the asphalt mix can help.
Hence, before beginning asphalt installation deciding which variable you are able to control can ease the task. For instance, preparing asphalt mix as per delivery temperature.
Keeping a few factors can help ease in the Asphalt Paving Toronto even in colder temperatures.
Pre Winter Check List For Asphalt Paving
Still, trapped in the fuss, is it too cold to pave?
Well, going through these key determining factors can help paving the pavement right without the adverse effect of low temperature.
#1: Ground Temperature
What’s the foundation temperature of the pavement? In most cases, the ground temp or temp of the foundation supporting pavement is a crucial factor.
Generally, installers don’t being the process when the ground temp is less than a certain point.
The cold the base is, the faster asphalt would lose its heat, making it difficult or entirely impossible to acquire appropriate compaction.
Moreover, the time available for compaction (TAC) signifies the time available for rolling to compact asphalt before it loses its heat and hardens.
#2: Lift Thickness
What is the final thickness of the asphalt pavement?
The thinner the asphalt layer is the quicker heat passes off. In short, in low tempt, the workers have a small window for functioning on thin asphalt.
Thicker Asphalt pavement holds heat much longer than thinner ones. However, the asphalt-retained heat isn’t linear but exponential.
For instance, a 3-inch pavement would preserve heat 4 times longer than a 1.5-inch asphalt installed in similar conditions using the same mix.
#3: Mix Delivery Temperature
What’s the distance between Jobsite and asphalt plant?
Asphalt is warm when it transports away from the plant. However, during the transition to the worksite, it cools down. In many cases, due to greater distance, it can be entirely unusable upon delivery.
Crusts on the top layer would lead to an inferior quality of pavement reducing the total life expectancy of pavement.
Nonetheless, different transport procedures can help preserve asphalt during transportation. Even then, in long-distance, these methods might be unsatisfactory.
#4: Ambient Air Temperature
The factor has a relatively trivial impact on the cooling rate of HMA. Nevertheless, the ambient air temperature accompanied by wind creates a situation. This leads to both conductive and convective heat transfer.
In this situation, heat dissipates to the base layer due to conduction and to air by convection. With greater wind speed, the process works more quickly eliminating heat from the HMA.
All in all, hot mix asphalt (HMA) temperature while the rolling process determines the final compaction results. Hence, taking ambient air temperature is critical for a long-lasting pavement.
#5: Solar Radiant Flux
The factor is the effect of the sun on the temperature of HMA. The next heat loss means the difference between the sun’s heat absorbed by asphalt and the heat radiating off into the air.
Simply, it means the sunrays help in lessening the cooling rate of asphalt. While Winter Asphalt Paving installation ensures the temp of HMA is at least 290° F for the mind layer before rolling.
These tips of asphalt paving would work for pre-winter asphalt paving installation. However, rather than asking, is it too cold to pave, our clients have other questions.
What about Winter Asphalt Paving. So, here are some helpful tips…
Is It Too Cold to Pave Asphalt Driveways In Winter?
As an asphalt paving contractor, what’s most challenging is Winter Asphalt Preparation and installation. Typically, we recommend holding off on the project till winter.
Still, we go for winter asphalt paving as long as conditions are dry and son snow has fallen. In different words, winter asphalt installation is possible in mild winters or late fall.
Here are quick round the table QAs and Asphalt Winter Care Tips.
When’s The Best Time To Pave Asphalt?
The best time for asphalt pavement is spring or once snow melts.
The dry weather condition provides better compaction. However, the Asphalt paving preparation and installation process can be done in winter too.
The applicable time to begin the process is in mid winter or late fall. In fact, as long as the condition is dry and the ground is snow-free, winter asphalt paving is possible.
Don’t Pave on Frozen Ground
Laying asphalt on frozen ground is the worst mistake possible. Firstly, the asphalt mix would be of extremely poor quality. Secondly, it would lose heat immediately making it impossible for sufficient compaction.
Hence, once winter is over, potholes, cracks, and other pavement issues would be common. Moreover, we recommend leaving potholes during winter due to similar reasons.
Wait for Dry Weather Conditions
Asphalt installation requires a completely dry day. In short, it should not be raining or snowing, the ground should be dry.
Just like paving on a frozen area, going for asphalt paving in snow or rain would compromise its quality. Indeed, the temperature affects the hot mix asphalt’s compaction.
Colder weather requires a quick operation. Hence, the crew needs to be larger in order to achieve ultimate finishing while ensuring strength and durability.
