Engineered for High-Precision Interlayer Bonding, Bitumen Emulsion Spraying, and Heavy-Duty Pavement Construction
In modern asphalt pavement engineering, the structural durability of highway infrastructures relies heavily on the quality of interlayer bonding. A Tack Emulsion Sprayer (commonly referred to as an intelligent bitumen distributor or asphalt emulsion tack coat sprayer) is a pivotal piece of specialized highway maintenance equipment designed to deliver a uniform, micro-metered application of liquid asphalt emulsion (such as CRS-1, CRS-2, CSS-1h, or polymer-modified asphalt emulsions) onto road base layers prior to hot-mix asphalt (HMA) overlay placement.
As a leading China Tack Emulsion Sprayer Manufacturer & Supplier, HEM Group (HME TOP Machinery Equipment Co., Ltd.) leverages over two decades of academic research from Chang'an University and cutting-edge hydraulic-electronic control engineering to manufacture high-precision, heavy-duty asphalt distributors that guarantee zero-shear failure and optimal bond shear strength across extreme climate zones.
Addressing Total Cost of Ownership (TCO), Viscosity Management, and Operational ROI for International Contractors
Global civil engineering firms require tack coat application systems capable of dynamically adjusting liquid output based on real-time vehicle travel speeds. Our smart micro-computer controller regulates positive displacement asphalt pumps to maintain exact binder coverage regardless of speed fluctuations between 2 to 20 km/h.
Emulsified bitumens are thermal-sensitive fluids susceptible to phase separation if overheated or clogged if cooled below critical thresholds. Featuring automated diesel burners, thermal oil circulation jackets, and stainless heating coils, our sprayers regulate tank temperatures between 60°C to 180°C with digital accuracy.
Nozzle blockages represent a massive hidden operational cost during road construction. HME TOP equipment incorporates a dual-line automatic high-pressure air-flushing system that evacuates remaining emulsion from spray bars and individual nozzles within 90 seconds post-operation, eliminating manual scraping.

Systematic Pavement Preservations Solutions for Major Infrastructure Projects Worldwide
Expressways require exceptional shear stress resistance between the concrete base and hot-mix asphalt overlays to sustain heavy axle loading from commercial truck fleets. Our tack emulsion sprayers apply ultra-thin, highly uniform membrane coatings that prevent interlayer slippage under intense braking forces.
Truck-Mounted Intelligent Bitumen Distributor (6,000L to 12,000L Tank Capacity) with full hydraulic expansion spray bar and radar speed sensors.
Airfield runways demand exact binder distribution to guarantee high shear integrity during high-speed aircraft landings. Micro-metered spraying avoids binder-rich bleed spots that compromise friction coefficients and pavement safety standards.
Synchronized Chip Sealer or High-Accuracy Asphalt Sprayer equipped with computerized flow-meter feedback loops and real-time data logging.
Narrow city streets, intersections, and localized pavement repairs require compact maneuverability alongside instant spray activation. Our trailer-mounted and light truck-mounted tack sprayers offer rapid response capabilities for municipal public works departments.
Trailer-Type Emulsion Sprayer (1,000L to 3,000L) with hand-held flexible spray lance and auxiliary engine drive system.
For preventative maintenance and crack reflection mitigation, spraying polymer-modified bitumen emulsion combined with immediate aggregate application provides an impermeable barrier against rainwater infiltration.
HEM Synchronized Chip Sealing Machine combining aggregate distribution and bitumen spraying in a single pass.
Founded in 1998 by esteemed professors from Chang'an University (China's premier university for highway engineering and transportation machinery) and seasoned road construction veterans, HEM Group (originally Xi'an Hongda Communications Technology Co., Ltd.) represents the pioneering wave of independent R&D in high-end road building equipment in China.
Recognized as a certified "High-tech Enterprise" by the Shaanxi Provincial Department of Science and Technology in 2006, our research institute has spearheaded groundbreaking advancements in mechanical dynamics, engine power matching, hydraulic transmission systems, and digital micro-electronic control platforms.
In 2017, to serve an accelerating international demand, HME TOP Machinery Equipment Co., Ltd. was established as our global export arm, streamlining technical consultation, international logistics, customs documentation, and field after-sales support across 60+ sovereign territories.
