In order to improve the precision of the crushed stone distributing of the asphalt macadam synchronous chip sealer.The working principle of the asphalt macadam synchronous chip sealer gravel distributing was explained in detail, and the factors affecting the precision of the macadam distributing were analyzed. In terms of structure and control system, improved methods to improve the distribution accuracy of crushed stones are given to ensure that the distribution accuracy of crushed stones of the synchronous asphalt sealer meets the construction requirements.

In recent years, the role of asphalt macadam synchronous sealing truck has been increasingly recognized. Despite the slowdown in the growth momentum of the construction machinery industry, the sales of synchronous sealing vehicles are still rising steadily. The main performance indicators of the asphalt macadam synchronous sealing truck are the spraying (spreading) ability of asphalt and macadam and the liquor (spreading) precision.

To ensure that the spreading accuracy of crushed stone is higher than the national standard and fully meet the construction requirements, it not only requires reliable parts design and accurate processing, but also requires good stability of the hydraulic control system for crushed stone distribution. It also requires the operator to fully understand the synchronous sealer. Skilled operation. This paper analyzes the principle of rubble spreading, analyzes the factors that affect the precision of rubble spreading, and proposes two improvement strategies in terms of mechanical structure and control system, so as to improve the precision of rubble spreading and ensure that the gravel spreading of the asphalt and rubble synchronous sealing truck. The quality meets the construction requirements.
