As highway transportation networks serve as the arteries of the national economy, the quality of pavement maintenance is directly related to traffic efficiency and transportation safety. Cracks, one of the most common pavement diseases, seem minor at first but will continue to expand under the repeated effects of rainwater infiltration, temperature changes and vehicle loads, eventually leading to structural damage to the pavement. According to the latest 2026 data from the Ministry of Transport, the annual road maintenance cost caused by untreated pavement cracks exceeds 12 billion yuan. Therefore, choosing a reliable crack repair material is a core link to reduce maintenance costs and extend road life. Suzhou Fanuode Engineering Enterprise Co., Ltd., with more than ten years of R&D experience in pavement maintenance materials, has launched a new generation of high-performance asphalt crack sealant, providing a new choice for the road maintenance industry that combines economy and durability.
Fanuode asphalt crack sealant adopts industry-leading modified asphalt technology, using high-quality heavy-duty asphalt as the base material, incorporating SBR rubber polymer, nano-scale antioxidants and anti-aging factors, and is made through advanced processes such as 24-hour constant temperature polymerization and three times of homogeneous grinding. The core performance of the product far exceeds industry standards: in high-temperature environments, the softening point of the colloid is stable above 90℃, and it will not flow or deform even under the extreme condition that the surface temperature exceeds 60℃ in summer in the south; in low-temperature environments, the brittle point is as low as -35℃, which can adapt to the severe pavement shrinkage and deformation in winter in the north and avoid colloid cracking and detachment. At the same time, the product has excellent anti-aging performance. Verified by artificial accelerated aging tests, its service life can reach more than 5 years, which is twice that of traditional sealing materials. In addition, the product has passed the ISO14001 environmental management system certification, and VOC emissions during heating are 30% lower than the industry average, making it more green and environmentally friendly.
In terms of construction convenience, Fanuode bitumen filling sealant has also been targeted optimized. The melting temperature range of the product is set at 170℃-190℃, which is compatible with mainstream sealing equipment on the market and can be put into use without additional modification. It has excellent fluidity after heating, and can automatically penetrate into various cracks with a width of 0.1cm-5cm without manual auxiliary filling. And it has a fast curing speed, and can reach traffic strength in 1 hour at room temperature, greatly shortening road closure time. The construction process has also been simplified: only simple cleaning of the cracks is required, and sealing can be carried out directly without complex grooving, saving more than 60% of the time compared with traditional construction processes. In addition, the bonding strength between the colloid and the pavement reaches 1.8MPa, which can withstand repeated rolling of heavy-duty trucks, effectively preventing rainwater and sediment from invading the cracks and blocking the development of diseases from the source.
In expressway maintenance, Fanuode asphalt crack sealants shows excellent performance advantages. Taking the maintenance project of Jiangsu section of Beijing-Shanghai Expressway as an example, the daily traffic volume of this section exceeds 80,000 vehicles, and heavy-duty trucks account for 40% of the total, so pavement crack repair faces the test of high-intensity load. After using Fanuode sealant, the construction team completed the crack treatment of 50 km section in only 3 days, and the construction efficiency was 40% higher than that of traditional materials. After 3 years of traffic inspection, the good rate of the repaired parts still remains above 95%, without cracking or detachment, reducing 2 times of repeated repair compared with traditional materials, and reducing the maintenance cost per kilometer by 3,000 yuan.
In view of the diversity of expressway cracks, Fanuode provides customized solutions: for fine cracks of 0.1cm-0.5cm, fine-particle size sealant is used to ensure full penetration; for medium cracks of 0.5cm-2cm, standard products are used to achieve rapid filling; for wide cracks of more than 2cm, special grooving equipment is used to widen the cracks to 1.5cm-2cm first, and then pour the sealant, which greatly improves the bonding area and repair strength.
In municipal road maintenance, Fanuode concrete road crack sealant material solves the problems of limited construction time and great traffic interference. Taking the municipal road maintenance project in Jing'an District, Shanghai as an example, the construction team used Fanuode sealant to complete the crack repair of 20 roads during the window period from 10:00 PM to 6:00 AM the next day. The 1-hour fast curing characteristic of the product ensures that the road is opened smoothly before the morning traffic peak, without affecting citizens' travel.
For vulnerable areas such as around manholes and bus stops in municipal roads, Fanuode has launched a high-elastic special formula, and the elongation rate of the colloid reaches more than 500%, which can adapt to the deformation caused by uneven settlement of the pavement and effectively prevent the cracks from spreading around the manholes. In the bus station maintenance project in Xuanwu District, Nanjing, the good rate of the parts repaired with this formula still remains above 98% after 1 year of frequent rolling.
In airport runway maintenance, Fanuode asphalt crack sealant meets the strict requirements of high flatness and high durability. In the runway maintenance project of Shanghai Pudong International Airport, the construction team used Fanuode sealant to repair the fine cracks on the runway surface, and the surface flatness error after repair was controlled within 0.5mm, which met the standard requirements of the International Civil Aviation Organization. The high elasticity of the product can adapt to the huge impact force during aircraft take-off and landing, avoiding the recurrence of cracks.
In view of the special needs of airport runways, Fanuode sealant adopts a low-smoke formula, which does not produce irritating odor when heated, ensuring that the construction process does not affect the normal operation of the airport. At the same time, the anti-aging performance of the product has been verified by ultraviolet accelerated aging test, and its performance remains stable under strong ultraviolet radiation, which can meet the use requirements of airport runways exposed to outdoor environment for a long time.
As a technology-based enterprise focusing on pavement maintenance materials, Fanuode has always adhered to the concept of "technology-driven quality". Its products have passed ISO9001 quality management system certification and road material testing standards of the Ministry of Transport. The company has many patented technologies, and its R&D team is composed of senior road material experts and chemical engineers, who can customize exclusive material formulas according to the climate characteristics and road conditions of different regions. In addition to providing high-quality products, the company has also established a perfect after-sales service system, providing customers with full-process support from construction plan design to on-site technical guidance. In the future, Fanuode will continue to increase R&D investment, focus on the innovation of green and environmentally friendly maintenance materials, and contribute to the construction of sustainable road traffic infrastructure.
