Asphalt Crack Filling Equipment Advantages

Compared to large and medium-sized vehicle-mounted or ride-on equipment, the compact, push-type asphalt crack sealer offers multiple key advantages for small-scale road maintenance:

▪ High Portability: YG asphalt crack sealing equipment weights only 120-150kg, the unit features a push-type design that eliminates the need for large transport vehicles. It can easily access narrow roads, residential streets, and other work areas inaccessible to large or medium-sized equipment, and can be moved and operated by a single person.

▪ Flexible Power Options: Supports multiple power and heating methods, including LPG, solar power, and self-priming. In field operations without external power sources, hot tar crack filler machine can be powered by a lithium-ion generator or solar panels, eliminating energy constraints.

▪ Excellent Heating Efficiency: YG asphalt crack sealer machines are equipped with a professional diesel burner and a thermal oil circulation heating system, it rapidly heats the crack-filling compound to the required working temperature. The constant-temperature control system effectively prevents material scorching and aging, ensuring high-quality crack sealing.

▪ Controllable Costs: YG small crack fill machine for sale is significantly lower than that of large and medium-sized crack sealing machines. Prices for wear-and-tear parts are transparent and replacement is convenient. Additionally, the cost of crack sealing compound can be further reduced by selecting different models based on construction requirements.

▪ Low Operational Threshold: No professional driving license is required; operators need only master basic temperature control and material dispensing operations. A skilled worker can complete 2,000–3,000 meters of crack sealing per day, with an average daily material consumption of just 200–300 kg, achieving operational efficiency far surpassing manual filling.

Asphalt Crack Filler Machine Applications

This compact, push-type asphalt crack sealer machine is not limited to highway maintenance; its applications are extremely broad:

▪ Highways and National/Provincial Roads: Seals early-stage cracks in the pavement to prevent rainwater infiltration.

▪ Municipal Streets and Squares: Flexibly addresses fine cracks between densely packed urban buildings.

▪ Airport Runways: Used for filling joints in concrete or asphalt surfaces.

▪ Industrial Parks and Campus Areas: Compact and quiet, making it ideal for short-distance, multi-location maintenance operations.

How to Repair Driveway Cracks with a Asphalt Crack Filling Equipment: A Step-by-Step Guide

Using a professional asphalt crack sealer machine to repair cracks in your driveway or garage floor not only improves the appearance but also prevents damage to the subgrade caused by water penetration. Here is the expert-level procedure:

Step 1: Preparation & Safety

▪ Clear the area: Remove all vehicles and obstacles from the area to be repaired.

▪ Safety Precautions: Wear heat-resistant gloves and safety goggles, and ensure the generator has sufficient fuel.

Step 2: Clean and Route the Cracks

▪ Routing: Use a pavement router to trim irregular cracks into uniform “V”- or “U”-shaped grooves, which increases the bonding surface area for the sealant.

▪ Dust Removal: Use a high-pressure air blower to remove loose stones, dust, and vegetation from the slot. Note: The crack must be completely dry; otherwise, the sealant may delaminate.

Step 3: Heat the Sealant

Place the asphalt sealant blocks into the hopper of the YG series asphalt crack sealer machine.

Start the LPG or diesel burner. Thanks to our thermal oil circulation heating system, the material will be evenly heated to the optimal flow temperature (typically 180°C–200°C).

Turn on the SLA-5000 intelligent temperature controller to monitor the temperature in real time and prevent the material from overheating and aging.

Step 4: Application / Filling (Precision Crack Filling)

▪ Preheat the hose: Activate the 5-meter electrically heated discharge hose to ensure there are no residual solidified materials inside the pipe.

▪ Precise injection: Hold the discharge nozzle and advance it at a steady speed along the crack. For pressure-fed models such as the YG-60L/80L, simply pull the trigger lightly to allow the sealant to penetrate deep into the crack.

▪ Smoothing: Use the built-in scraper or a manual smoothing tool to ensure the crack sealant is flush with the road surface.

Step 5: Curing and Reopening

▪ Curing Time: At room temperature, high-quality crack sealant typically cures within 15–30 minutes.

▪ Reopening to Traffic: Once the surface is no longer tacky to the touch, the lane can be reopened to traffic.

▪ Pro Tip: If this is your first time using the product, we recommend our YG-60L asphalt crack sealer machine. Its compact design and pumping system allow even beginners to achieve a perfect repair speed of 15 meters per minute, just like a professional construction crew.
