| Asphalt Transfer Vehicles in China: On Pause or in Shock? |
|

An Imported Technology
Asphalt transfer vehicles (ATVs) were first developed in the United States in the 1990s. Their proven success in the American market quickly caught the eye of savvy equipment dealers, who began actively promoting them to Chinese customers around the year 2000. However, ATVs have experienced a rather bumpy journey in China.
Early promotional efforts failed to open up the Chinese market. It wasn’t until October 2002 that things began to change. That year, Hebei Road & Bridge Group purchased a ROADTEC SB-2500B asphalt transfer vehicle through Beijing Rongshijie Company and deployed it on the Hangzhou Ring Expressway. This marked China’s first imported asphalt transfer vehicle. The machine attracted widespread attention on site and sparked considerable buzz in the industry.
Around the same time, SANY Heavy Industry launched its own research and development program for asphalt transfer vehicles under China’s national “863” high-tech plan. By September 2002, SANY had unveiled its LHZ25A model at the 6th Highway and Waterway Transportation Expo.
From then on, ATVs became a hot topic in China’s road construction sector.
A Rising Star That Faded
Following this wave of attention, both domestic and international manufacturers rolled out their own models. However, controversy has surrounded ATVs ever since. Objectively speaking, they do help improve paving quality. But convincing Chinese customers to adopt such an expensive auxiliary machine has proven difficult.
Compared to the bustling market scene just three or four years ago, today’s ATV market in China is eerily quiet. What happened? Is the industry calmly biding its time, or has it fallen into a deep coma due to entrenched construction practices and economic realities?
Luxury or Necessity?
In essence, an asphalt transfer vehicle is an auxiliary device: it is a sufficient but not necessary condition for high-quality pavement construction. Put simply, roads can be built perfectly well without it. So a machine that costs three to four million RMB but only provides incremental improvement is understandably a tough sell.
There has long been debate about whether ATVs make sense for China’s highway construction. While no one disputes their technical benefit, the real issue is whether they offer value for money given local conditions.
It’s worth noting that ATVs have seen consistent use in only a few regions, such as Inner Mongolia. This is partly due to the region’s long, narrow geography and large diurnal temperature swings, which make material segregation more likely. It’s also because local road authorities and project owners there specifically require ATVs and support their use through policy incentives.
For the rest of China, however, whether this paving method is suitable, cost-effective, and ultimately worthwhile still needs to be validated with hard data and long-term performance results.
Driving Change or Hitting a Bottleneck?
In China, several industry characteristics have hindered the widespread adoption of ATVs: tight cost controls, suboptimal equipment combinations, and the fragmented scale of road contractors. Many contractors own minimal equipment to maximize profit margins. As a result, investing in an expensive auxiliary machine is not a priority.
In Europe and the U.S., centralized batch plants are designed with environmental considerations in mind, and contractors often haul asphalt mixes over distances of more than 100 kilometers. In this context, transfer vehicles play a critical role in preventing temperature drops and material segregation during long hauls. Large contractors handle extensive paving mileage and are also responsible for long-term road maintenance, so any improvement in pavement durability directly benefits them financially.
In contrast, Chinese contractors typically have their own on-site mixing plants positioned within each 20–30 km section. Transport distances are short, so asphalt temperature drops only slightly (usually 3–5°C), and segregation is minimal. Asphalt is discharged directly from trucks into the paver, leaving little room for transfer vehicles to add value. This has led some to dismiss ATVs as redundant.
Breaking the Deadlock
Regardless of whether they support or doubt ATVs, most industry insiders agree on one thing: the technology works. The real debate is whether it delivers a good return on investment under China’s unique construction model.
Interestingly, at the 2004 Bauma China trade fair, even traditionally conservative European brands like Wirtgen’s Vögele and Sweden’s Dynapac surprised the industry by launching new ATV models (the MT1000-1 and MF250, respectively). This made it clear that debating regional paving methods had become irrelevant—transfer vehicles are part of the global trend and an important technology reserve.
So where does the problem lie in China? Owners and investors calculate carefully: will the long-term savings in maintenance offset the upfront cost of an ATV? Only time will tell. But a three- to four-million-RMB price tag certainly makes buyers hesitate.
China’s revised Technical Specifications for Highway Asphalt Pavement Construction now mention ATVs explicitly. Section 5.5.4 states:
Quote:“...When conditions allow, delivery trucks may unload asphalt mixes into a transfer vehicle for secondary remixing and continuous, uniform feeding of the paver...”
That phrase “when conditions allow” implicitly acknowledges the high cost barrier.
Future Prospects
Despite the recent lull, the trend towards continuous paving with ATVs is clear. Leading global brands now promote double-layer hot paving technology as the next big thing. In China, domestic players like XCMG, SANY, Dingsheng Tiangong, and Xinzhu have all joined the market with their own products.
As one industry expert bluntly put it:
Quote:“The benefits of ATVs are real, but some manufacturers overhype them—leading to disappointment. This reflects the restless, hype-driven mindset that still plagues parts of China’s construction machinery industry.”
Recent market quietness has tested ATV makers, forcing them to adapt and design models better suited to Chinese conditions. Some signs of recovery have already emerged: for instance, XCMG recently delivered three new ATVs, and a company representative told reporters that the market is entering another cycle of growth.
Summary
The asphalt transfer vehicle in China is neither dead nor fully alive—it stands at a crossroads. With better cost control, data-backed performance, and an evolving construction environment, ATVs are likely to earn their rightful place in China’s road-building arsenal.

| Introducing New Equipment: The Glory and Struggles of Scrapers |
|

A Century of Development
The scraper, a key piece of earthmoving machinery, has been evolving for over a century. As early as the 18th century, horse-drawn scrapers were used for short-haul soil transport. By 1883, the first fully metal-wheeled scraper was manufactured in the West.
In 1910, the United States built dedicated scrapers towed by tractors, while the Soviet Union began mass-producing wheeled scrapers in the 1920s. By 1938, the world saw its first self-propelled scraper, followed by twin-engine and chain-loader variants in the mid-20th century—culminating in the 1960s with the world’s largest scraper, boasting a 200 m³ bowl capacity.
China entered the scraper field in the 1960s. In April 1961, several institutions—including the predecessors of Yutong Heavy Industries, Tianjin Research Institute, and XGMA—formed a joint design team. Drawing on imported prototypes, they developed China’s first self-propelled scraper. The design was completed that August, and on December 22, 1962, the first prototype (C-6106) rolled off the line in Zhengzhou.
Scrapers: Built for Efficiency
Scrapers are unique in that they combine cutting, loading, and hauling in a single machine. They shine in medium-haul applications—roughly 200 to 1,200 meters—where they outperform the typical excavator–loader–dump truck combination in both speed and cost-effectiveness.
Recognizing this, China invested heavily in scraper research during the 1960s and 1970s. The CL7 model, trialed in 1972, adopted advanced hydro-mechanical transmission and full hydraulic control. It marked a major technical leap, earning a National Science and Technology Award in 1978 and even showcasing China’s progress at the 1975 Cologne International Fair in Germany. In 1978, two CL7 scrapers were used in a groundbreaking test on the Qinghai-Tibet Railway—China’s first industrial field trial for high-altitude road construction equipment.
A Legacy Now Struggling
Fast forward several decades: despite their engineering advantages, scrapers are now nearly phased out in China. Their work has been almost entirely replaced by flexible excavator-loader-dump truck combinations. By contrast, scrapers still handle around 40% of total earthwork in the United States.
Why has China’s scraper industry lagged behind after more than 40 years?
The Subcontracting Dilemma
Take the massive South-to-North Water Diversion Project as an example: planners calculated that 700 scrapers would be needed to tackle over 830 million cubic meters of earthwork. Yet in reality, scrapers were almost absent from the project site, despite engineers insisting they were the most efficient option.
The root cause lies in China’s subcontracting system. Scrapers are more specialized than excavators or dump trucks, and cost more upfront. For a 400-meter haul, two self-propelled Caterpillar scrapers can match three excavators and nine dump trucks. But tight profit margins and higher equipment costs make small to mid-sized subcontractors reluctant to invest in scrapers—especially given their narrower range of applications.
Even long-time scraper proponents like China Railway Construction Corporation face an uphill battle promoting them in today’s fragmented subcontracting environment.
Missing Market Drivers
In the 1950s and 1960s, Western embargoes forced China to reverse-engineer foreign machines. By the late 1960s, both a ZL45 loader and a chain-type twin-engine scraper were secretly acquired and copied. Decades later, loaders are now ubiquitous, dominating the construction machinery market. Meanwhile, scrapers are nearly forgotten—except for isolated success stories like the Holingol coal mine in Inner Mongolia, where shallow seams made scrapers highly profitable.
The lesson? Markets don’t build themselves. While only Yutong Heavy Industries persisted in scraper production, one company alone cannot nurture demand. Scrapers are more technically challenging to build than loaders, and without a strong market, few manufacturers are willing to invest.
A Path Forward
The dilemma is clear: no market means no manufacturers, and no manufacturers means no market. In fact, the construction machinery industry must take the lead in educating customers about modern, efficient earthmoving methods. Just as loaders gained popularity through joint effort, scrapers too can find their rightful place—especially as specialized contractors grow and labor costs continue to rise.
Caterpillar, which holds 95% of the global self-propelled scraper market, remains confident: despite setbacks, they believe that scrapers will eventually see a revival in China.

I just put in about 10 hours on my brand-new Liugong 913E, and here’s my initial take: - Operation: Overall, the controls feel smooth, the power is decent but nothing impressive, and the speed is on the slower side.
- Modes: I tried out E, P, and F modes, but honestly, the difference between them isn’t very noticeable.
- Fuel Consumption: This is the biggest surprise — it’s really fuel-efficient. I fueled up four drums before starting, plus whatever fuel came in the tank, did around 1,000 cubic meters of earthwork (conservatively estimated), and after 10 hours, the fuel gauge still shows half full. Hard to believe!
- Compared to the old 915D: When my 915D was new, it never went below 9 liters/hour even on light work. The 913E has noticeably lower power, but for light earthmoving on flat ground, it’s actually a perfect match.
