So many models or types of models, which one to select with as the ideal crack sealing paver to use on your projects? This all-inclusive guide eliminates the confusion. We will divide the crucial factors, including the size of a project and the efficiency of a melt system, maneuverability, and safety. Beauty, whether you have been a contractor since time immemorial or a facility manager with long-term experience, this article will make you be a wise investor, cut back on repair expenses in the long run and produce an impeccable, long-lasting performance each time.
Depending on the hot melt kettle’s size: Small crack sealing machines (30–200 liters), medium-sized crack sealing machines (300–500 liters), and giant crack sealing machines (600–1200 liters) are the three types of crack sealing machines.
Considering performance: There are four types of crack filling machines: self-propelled towing crack filling machines, vehicle-mounted crack filling machines, mechanical push-type crack filling machines, and towed crack filling machines.
An overview of a few popular fracture sealing devices is provided below:
The initial one is to gauge the average size and type of projects. There are three main types of crack sealing machine depending on the portability and capacity:
This type is smaller, maneuverable (commonly 10-30 gallon capacity) and used in small parking lots, driveways, sidewalks, and residential use. They are cost effective and not complicated to carry around, yet the output of production is low. They are ideal either to small scale contractors or in house property maintenance teams.
It is the workhorse of most medium to large-scale contractors. These machines have capacities of 50 to more than 200 gallons, have an inbuilt heating system, greater capacity, and in most cases, they have a powered application wand. They can be used in large commercial car parks, local and highways, and provide a compromise of great output and speed.
The biggest and strongest (250-500+ gallons) system. These are permanently attached to a truck chassis, have the greatest daily production, and are most adaptable to large highway, interstate and high volume municipal projects where 24 hour operation is necessary.
The machine you use also directly depends on what kind of sealant that you apply. Hot-pour asphalt crack sealer is practically the only contributor to professional and long-term outcomes.
This is a solid material in block form that has to be heated to an application temperature. Hot-pour sealant is a better bond and offers superior elasticity thus being the industry standard to use in lasting repairs. This will require a special crack melter applicator.
These are liquid ready-to-use sealants that do not need to be heated. They are generally less durable and only used on very small non-working cracks or temporary patches although simpler. Important Lesson: To maintain the pavement of professional and long-term pavement, it is better to focus on the machine that will be used as a hot pour crack sealer.
Your sealant performance and integrity largely rely upon how the crack melter is heated:
The heat is applied in the bottom of the tank holding the material. They are fast heating and generally less expensive. They however have the risk of overheating or scalding the sealant at the bottom and this can destroy the rubber polymer structure effectively shortening the life of the sealant. Be careful and keep an eye on the temperature.
These are high quality machines in which a heat-transfer oil (or other similar fluid) is used to wrap around the sealant tank. The heating of the oil is done in the burner then the hot oil heats the sealant indirectly, and uniformly. This design eliminates scorching and maintains the quality and elasticity of the sealant. This system is strongly recommended to high volume, professional users, who require guaranteed integrity of material.
Tank Capacity: Select a capacity that will enable you to work a full day without having to refill material too often, trade off between capacity and transport logistics (i.e. will it fit on your trailer/truck).
Agitation System: An efficient agitator (manual crank or hydraulic driven) is essential in ensuring that the sealant is uniformly mixed during its melting. This prevents settling of filler material and the application is uniform and smooth.
Application Wand and Valve Control: Find a convenient, comfortable wand. The process of discharge valve should give the exact instantaneous control over the flow of the hot-pour asphalt with the minimal waste, thereby guaranteeing professional smooth application bead (or overband).
Safety and Usability: Such features as pressure relief, insulated handles, and the clear display of temperature cannot be compromised on safety. The cleaning and maintenance should be made easy so that the downtime will be minimized and the life of equipment will be increased.
Burner Fuel and Efficiency: Compare the type of fuel (propane, diesel, etc.) and the BTU rating. Efficiency of a burner will save the operating cost in the long run, but cannot be at the expense of the heating rate.
The best crack sealing paver machine will be one that matches your project size, choice of material and budget with high quality engineering. An initial outlay on an oil-jacketed, tow-behind unit might be expensive, but the savings in time saved in production and material wastage and the high repair lifecycle will soon pay off.
Order a SINOTO machine that has accurate temperature regulation and stable application system. This way, you are not only doing the right thing by filling cracks but you are doing the right thing of maintaining pavement in a good condition, this will be an additional service that will be appreciated by your clients in the years to come.
