 Abstract- In Vietnam so far, during the stage of cleaning up the road surface before spreading asphalt concrete, air compressors or blowers to blow dust and use brushes to collect discrete materials were normally used. Because This activity has generated dust, causing serious dust pollution to the surrounding air environment. The concentration of dust in the air of places, where there are many dust blowing activities, often exceeds the permitted standard more than dozens of times. There have been many proposed solutions to minimize the amount of dust generated as well as minimize the impact in the road blowing dust such as, but these solutions are not really effective. After a short period of research, scientists from the Institute of Transport Science and Technology completed the design and manufacture of road broom sweeper for road surface cleaning and recover small particles on the road surface when executing asphalt concrete layer. The equipment meets all criteria of pavement surface roughness and it does not cause dust.

The paper presents an overview of some issues in the design and manufacturing research that have been solved to create road broom sweeper for surface cleaning and recover small particles on the surface when executing asphalt concrete layer, promptly meet construction works and contribute to reducing environmental pollution in our country.
