1)spraying bitumen, 2)spreading aggregate, 3) one touch operation save bitumen and labor, 4) never clogging, 5)high accuracy - details see: https://www.machineto.com/chip-sealer-for-road-surface-treatment-10093978

1 (Main performance)

a) All operations can be performed by one operator in Cab

b)Asphalt spraying rate is controlled by computer which is independent of the truck speed.

c) Chipping spreading rate is controlled by computer which is independent of the truck speed.

d) An intelligent linkage between asphalt and chippings spreading systems.

e) Advanced heating and circulating system, to ensure the asphalt pipelines and nozzles “not to be blocked” and “not need to be washed by diesel oil”.

f) Spraying pipe can be folded and lifted by hydraulic system.

g) Uniquely combined aggregate bin with lower height, which is advantaged to work under viaduct and tunnel.

h) Control system introduces modularization design, has very reliable working performance and convenient troubleshooting.

i) Function of heating and insulation during driving.

j) Equipped with thermal oil heating and insulation hand spray bar which is able to spray on the special places on the road.

k) To realize fully three-overlapping asphalt spraying at two sides which improved the sealing quality.

l) Opening and closing of the doors of aggregate bin are controlled by pneumatic control valve. Every door of aggregate bin and nozzle can be controlled separately.

m) Equipped with Monitoring System, working specifications can be displayed on display screen at any time.

n) With functions of suck-in and discharge, can realize the asphalt loading and discharging.
