Background
Asphalt pavement refers to various types of pavement that are made by incorporating into mineral materials a road asphalt material. The asphalt binder improves the capability of the paving aggregate to resist damage of traveling vehicles and natural factors to the pavement, and enables the pavement to be smooth, less in dust, impermeable and durable. Therefore, asphalt pavement is a high-grade pavement which is most widely used in road construction, and the asphalt structure layer of the asphalt pavement belongs to the category of flexible pavement, but the base layer of the asphalt pavement can also adopt rigid cement concrete or semi-rigid hydraulic material besides flexible material.
The steel wheel road roller is a mechanical device for compacting various building and road building materials by utilizing the gravity and vibration of the steel wheel road roller. In road construction, the compactor is most suitable for compacting various non-sticky soils, gravels, gravel mixtures and various asphalt concrete materials, so that the compactor is widely applied; a pneumatic tire roller is a machine for compacting a road with a plurality of pneumatic tires. The rolling wheel of the pneumatic tyre roller adopts a pneumatic tyre, and is generally provided with 3-5 front wheels and 4-6 rear wheels. If the inflation pressure is changed, the grounding pressure can be changed, the pressure adjusting range is 0.11-1.05 MPa, the tire type road roller adopts a hydraulic, hydraulic or mechanical transmission system, is driven by a single shaft or a whole shaft, and is supported by a wide-base tire hinged frame structure at three points. The compacting process has a kneading effect, so that particles in a compacting layer are embedded without being damaged, and the compacting layer is uniform and compact.
However, when the asphalt road is constructed at present, asphalt is generally directly paved on a road base layer and compacted to form the asphalt road, but the asphalt road paved by the construction method can not be tightly combined with the road base layer, so that the asphalt road is easy to bulge and crack, and the asphalt road can not be used continuously; and when the mountain land is under construction, often can't in time supply the road roller machinery of damage, disturb the progress of construction, make the time of construction prolong.
