What kind of asphalt concrete paver is divided according to the way of walking?

What kind of asphalt concrete paver is divided according to the way of walking?

Answer:

(3) tire paver on tire under gravity and provide the advantages of adhesion, transition to run faster, good mobility, the subgrade bulge absorption ability, operation is easy to form a smooth curve edge. Its disadvantage is that the force is small, in the paving width is larger, thicker layer when it is possible to produce a skid in addition, the phenomenon was sensitive to the need for Subgrade of ups and downs, automatic leveling device to help improve the smoothness of pavement and pavement construction. The maintenance work can be used in a variety of ways.
(2) the crawler paver is generally large or ultra large paver, the utility model has the advantages of small ground pressure, good adhesion, paving operations run smoothly, no skid phenomenon. Its disadvantages are poor mobility, the subgrade bulge absorption ability, bend when working layer edge is not smooth enough, and the complicated structure, high manufacturing cost, for the construction of large pavement engineering.
In accordance with the mode of walking, the asphalt paver is divided into two types, tow and self-propelled, of which the self-propelled type is divided into caterpillar type and tire type(1) towed pavers is receiving, transportation, material and chat ironing work device is installed in a particular frame, paving material transport by truck towing or pushing. It has the advantages of simple structure, low manufacture and use cost, but due to poor quality of paving can small, pavementmaintenance is only suitable for low grade highway.
