1. Asphalt and aggregates can be sprayed (spreaded) synchronously to ensure the effective adhesion of asphalt and chips;

2.  All operations can be performed by one operator in the cab. The intensity and cost of labor can be decreased greatly.

3.  The application rate of asphalt and chips are all intellectually controlled by the computer. The application rate is not affected by the variation of truck speed with high precision.

4.  Advanced heating and circulating system can ensure the asphalt pipelines and nozzles unblocked and no need to be washed by diesel oil.

5.  The patented technology of combined aggregate bin with lowered height is an excellent solution for construction work inside of the tunnel, which can meet the requirements for all kinds of road construction works.

6.  The reasonable counterweight design for the whole vehicle can ensure the relative stability of center of gravity in uphill construction and safe, smooth and reliable construction;

7.   Effectively realize zero-overlapping spraying of asphalt at two sides and improve the sealing quality;

8.   The asphalt system with perfect performance can spray not only hot asphalt but also heavy-traffic asphalt, emulsified asphalt as well as modified asphalt and crumb rubber asphalt;

9.   The whole machine has reliable performance, convenient operation, low-cost maintenance and high-cost performance through many times validation of project/construction.
