Asphalt is the residue of petroleum, but these residues can also bring great convenience to our life. Asphalt has a strong adhesion effect and can withstand high temperatures. It is an effective material for road construction and water leakage prevention. Next, Jinan asphalt material manufacturer will tell you about asphalt pavement joint construction and compaction technology.
In road construction, the service life, durability and other aspects of asphalt pavement should be improved in many ways, so as to ensure that the mixture has a reasonable mix design. If the mixture proportion is not compacted in multiple directions during optimization, the actual function of asphalt pavement will be reduced. Compaction treatment of asphalt pavement is mainly to reduce the gaps in the mixture in many ways, ensure that the actual compactness of the pavement is effectively improved, and fundamentally promote the service life of asphalt pavement.
The joint construction I of asphalt pavement shall be carried out by two pavers. First, 10~20cm width shall be left at the position where the mixture is paved and no compaction construction shall be carried out. Then, 5~10cm thickness of the paving layer will be overlapped. The bridging and rolling construction shall be carried out through the operation of hot joint to ensure that the joints are eliminated.
If the construction joint belongs to the transverse type, it shall be treated through the flat joint. The longitudinal extension of the construction joint I shall be measured with a ruler. The position where the ruler falls off from the paving layer shall be taken as the main position for crack treatment. The joint saw shall be used to cut and remove it.
When the paving construction is carried out again, the dust existing in the joint construction I shall be cleaned up first, and the paving construction shall be carried out at the joint position by the paver, and the rolling construction shall be carried out by the steel cylinder roller in the way of transverse compaction. First, the cross joint construction shall be carried out from the pavement, and then the construction shall be carried out towards the new pavement.
