Main construction process
1 free slotted direct filling operation process
1.1 Clear the debris and dust in the seam and blow it with compressed air.
1.2 Use of liquefied gas burner to crack the cracks to ensure that the cracks dry.
1.3 will be heated to the required temperature of the filling glue into the seam, control the filling of the filling volume, spring and the road is flush or slightly lower than the road, autumn and winter than the road 2-3 mm.
2 slotted filling operation process
2.1 Slot location along the crack slot grooving, slot width of at least 1.2 cm, slot depth of 1.2-2.5 cm, the best aspect ratio is best controlled within 2: 1.
2.2 Remove the loose edge part and use the wire brush to handle the stripped part.
2.3 Clear the debris and dust in the seam and purge with high pressure air or hot air.
2.4 use of liquefied petroleum gas burner on the cracks to dry, to ensure that the cracks dry.
2.5 will be heated to the required temperature of the filling glue into the tank, and asked to open the irrigation slot filled with filling.
2.6 In order to be able to advance the construction section of the open traffic, reduce the traffic generated by the construction work pressure, pouring a small amount of sand or fine aggregate on the pouring glue to prevent the sticker to advance the traffic.
