The comparison of construction machinery in rockfill embankment construction is discussed from the angles of loader, excavator and bulldozer. The comparison and analysis of compaction technology are also discussed from the point of paving and leveling of gravel packing. In this case,Small Road Roller – Shanghai Doan Machinery Technology Co.,Ltd
Loader
Loader power is good, walking speed, suitable for short-distance transport, in the gravel soil roadbed, can be carried out by lifting, lifting equipment, leveling the site, repair sidewalk, rough. When the transport distance is close, from the shovel from transport. When the distance is far away, it is necessary to carry out loading work with the dump truck. Loader construction work is divided into V-type operating method, I-type operation method, L-type operation method, T-type operation method. The actual productivity QZ that the loader achieves per unit time can be expressed as follows:
QZ = 3600qKHKBtT / tKs
Where, q is the loader rated bucket capacity, m3; KH for the bucket full coefficient, blasting large rock after taking 0.8 ~ 0.95; KB for the time utilization factor; tT for the class time, h; A bucket of the cycle time, s; Ks for the filler loose coefficient.
Excavator
Excavator is the main earth and stone construction machinery, which is characterized by high efficiency, yield, but mobility is poor, in the highway construction, encountered gravel embankment and embankment and other large projects, the selection of mining Machine with dump truck construction is more reasonable. In this case,
Crushed stone roadbed construction, the general selection of crawler excavator, walking system for the track, more suitable than the tire type gravel roadbed construction. Excavators can be used to load, trim slopes, broken packing, rough equality. Operating capacity is one of the main technical and economic indicators of the excavator, said the unit time, the bucket from the work surface dug and unloaded to the transport vehicle or dump earth mass. 
Bulldozer
Bulldozer is gravel soil roadbed construction of the main rough, paving machinery. As the gravel surface is not smooth, and the construction face contains prominent, sharp rock, it must be used more power crawler bulldozer flattening. (In the flattening process repeated rough flat, so that loaders and rollers are not easy to damage the tire) should not be flattened with a small power bulldozer, so as not to produce re-isolated packing.
