1、Choose the suitable model according to the type of pavement project

(1) For cement concrete pavement, tyre-driven tandem vibratory roller can be used.

(2)For asphalt concrete pavement, driven vibratory roller should be used.

(3) For the subgrade of high pavement roadbed, tyre rollers or tyre-driven vibratory rollers may be used for compaction to obtain uniform compactness.

(4) Static-acting bare wheel rollers may be used for repairing pavement.

(5) For compaction of clay soils, cam tamping type rollers may be used for construction.

(6) Compacting pavements and repairing black pavements, roadbeds and initial compaction of road surfaces may be carried out with rollers under 4.5 tonnes.

(7) gravel and crushed stone roadbed and asphalt concrete pavement, the final compaction can choose 10-14 tonnes or larger roller to construction in order to make large blocks of material displacement.

2、Learn to negotiate price, understand certain evaluation standards

At present, the used road roller price assessment standards are generally based on the age, condition and mileage. For example, one year old Santana condition without major problems, the price will drop 5,000 yuan, if the model is a little older, the price will continue to fall. If it is two years old, the decline is still large, generally by 10 per cent in descending order.
