Road Construction & Pavement Equipment
Concrete laser screed · Mini roller · Crack sealer · Thermoplastic preheater
YG Machinery provides a complete line of advanced road construction and pavement maintenance equipment designed for high efficiency, precision, and durability. Whether you need laser‑guided concrete leveling, compact compaction in narrow spaces, hot‑pour crack sealing for asphalt, or reliable thermoplastic melting for road markings, our machines deliver superior results. From large warehouses and airport aprons to municipal roads and parking lots, YG equipment helps contractors reduce labor costs, improve surface quality, and accelerate project timelines.
🏗️ Concrete Laser Leveling Machine – YGJX Series
The YGJX series concrete laser leveling machines combine laser‑guided precision with integrated leveling, vibration, and slurry raising to produce exceptionally flat concrete floors. Available in four models (YGJX31, YGJX32, YGJX33, YGJX34), they are ideal for warehouses, airports, factories, and large commercial slabs. The laser receiver continuously adjusts the screed head height relative to the reference plane, while the vibration system compacts concrete and fills voids — all in one pass. Compared to traditional methods, these machines drastically improve flatness and levelness, reduce rework, and cut labor costs.
All models feature a 2500mm screed width, 500N exciting force, and 50Hz vibration frequency. The YGJX31 is powered by a 2.0kW generator set, while YGJX32/33/34 use a 13hp GX390 electric‑start engine. Running speeds reach 45‑65 m/min depending on the model, with self‑leveling or hydraulic‑controlled screed heads, and laser control systems powered by microcomputer laser scanning. The machines weigh from 295 to 410 kg, offering excellent maneuverability on wet concrete. For projects demanding superior floor flatness (Fmin requirements), the YGJX series is the go‑to solution.
🚜 Mini Road Roller – YG-600S Compact Vibratory Roller
The YG-600S mini road roller is a lightweight, portable vibratory compactor specifically designed for small‑scale construction projects such as community road repairs, courtyard compaction, trench backfill, and sidewalk paving. With a weight of only 350 kg and a steel drum size of 426×600mm, it easily navigates narrow spaces where large rollers cannot enter. The roller offers two engine options: Honda GX160 gasoline (5.5hp) or Changfa 170FE diesel (3.8hp), both driving a hydraulic travel system with bidirectional travel and a speed of 2.4 km/h.
Despite its compact footprint, the YG-600S generates an exciting force of 15 kN at a vibration frequency of 70 Hz, achieving over 90% compaction density on asphalt or soil subgrades. The automatic vibration clutch engages only when needed, and the compact design includes a lifting ring for easy transport by small trucks. Climbing capacity is 25%, making it suitable for gentle slopes. For municipalities, landscaping crews, and utility contractors, this portable road roller offers outstanding value, low fuel consumption, and simple maintenance.
🛣️ Asphalt Crack Sealing Machine – YG 50L/80L/100L
The YG series asphalt crack sealing machines are hot‑pour crack fillers designed for efficient, long‑lasting repair of pavement cracks on highways, municipal roads, parking lots, and airports. Three models — YG-50L, YG-80L, and YG-100L — cater to different job scales. The 50L and 80L units feature liquefied gas heating with heat‑transfer oil for fast melting, push‑type walking with brake, and solar panel + battery power for off‑grid operation. The 100L model adds an Italian diesel burner with heat‑transfer oil circulation, electric stirring, a 5‑meter hand‑held sealing tube, and a trailer axle for easy transport.
Filling speed ranges from 10 m/min on the 50L to 20 m/min on the 100L, and the temperature control system maintains sealant at approximately 180°C to prevent burning. The asphalt pump on the 80L and 100L models delivers pressurized injection, ensuring deep penetration and strong adhesion to crack walls. The YG-100L also includes a 2kW imported generator to power the electric stirrer and keep the discharge pipe at a constant temperature — ideal for cold weather or long workdays. These hot pour crack sealers dramatically increase crack repair productivity while reducing material waste.
🔥 Thermoplastic Preheater – Mechanical & Hydraulic Melters
The YG series thermoplastic preheaters (hot melt kettles) are designed to efficiently melt road marking paints (thermoplastic materials) for highway, parking lot, and urban street marking projects. Two main variants are available: mechanical single/double cylinder models and hydraulic double cylinder models. The mechanical series includes the YG-CK300 (single cylinder, 300kg capacity, 6.5hp diesel) and YG-CK600 (double cylinder, 2×300kg, 8hp diesel). The hydraulic series offers YG-CK800, CK1000, and CK1200 with 2×360kg, 2×500kg, or 2×600kg capacities, powered by a 15hp electric‑start diesel engine.
All models use high‑efficiency LPG direct injection burners and high‑density aluminum silicate insulation that saves up to 20% gas. Both mechanical and hydraulic units feature stainless steel tanks, high‑carbon steel bottoms, and vertical paddle mixers for uniform heating and preventing scorching. Hydraulic models enable forward/reverse stirring for even material distribution and can supply two marking machines simultaneously. Safety features include automatic disconnection for mechanical units (emergency stops) and overload relief valves on hydraulic models. Daily output ranges from 600–800 m² on the CK300 up to 1200–2000 m² on the CK1200, making them essential for professional road marking crews.
