road repair Micro Surfacing Paver

Yihong Company is a China-based micro surfacing paver manufacturer, which is dedicated to providing global customers with the best intelligent slurry seal solutions.

Our intelligent slurry paver is a patented road maintenance machine that is developed on the basis of the internationally advanced technologies.

It is widely used for the preventative maintenance on all kinds of roads,water-proof layer construction in the new roads and micro-surfacing construction in the express ways. 

In order to offer customers better quality products, we purchase key components from renowned suppliers, like Sino Truck low speed chassis ZZ1256, Germany BUCHER hydraulic valve, Italy ITALVIBRAS vibrating motor. Thanks to our consistent focus on product improvement, our intelligent slurry seal machine is CE, CCC certified, and can treat many pavement diseases like friction resistance reduction, cracks and ruts, so as to improve the pavement's anti-slide, waterproof performance and evenness for greater traveling comfort. As a result, Yihong intelligent slurry paver is widely used in the construction of slurry sealing, modified slurry sealing and micro-surfacing. 

1. Working Theory

Slurry, a combination composed of bitumen, emulsion, aggregate, water, filler and additives mixed at some ratio, is to be paved uniformly on the construction roads. After several procedures such as wrapping, breaking of emulsion, separation of water, evaporation and solidification, the slurry will form a dense, thick, stable, wear-resistant road surface sealing, which definitely improve the road performance a lot. Slurry seal technology can be divided into common slurry seal, modified slurry seal.

2. Wide application

A. Old road maintenance

The old road will become cracked, soft, aged and worn which due to the long lasting vehicle compaction and the result from the sun, wind, rain and freeze. If we adopt slurry seal technology before the road become worn, the old road surface will be the characteristic of being water-proof, skid-resistance, wear-resistance and it will help to extend the life span for the road. And if we adopt slurry seal technology on the road with cracks, it will repair the old road and improve the road performance and extend the life span. The traffic can come back to normal as soon as the construction is finished.

B. Wearing layer in the new asphalt road building

On top of the new road, we can pave a new slurry layer at 5mm thickness in order to improve the road performance in water-resistance and wear-resistance. And it can help to make the road more plain and good appearance.

C. Wearing layer in the sand and rock road

We can adopt slurry seal technology on the compacted sand and rock road which will have the same character as the asphalt road and improve the wear-resistance performance.

D. Road surface and bridge in cement concrete

The slurry seal has got the good absorbability on the cement concrete. When we find any cracks or non-smooth areas in the cement concrete roads, we can adopt slurry seal technology to improve the surface appearance, enhance the planeness of the road and extend the road life span. The slurry seal will work as the coating on the bridge, which will not increase the bridge weight.
