1.Semi-closed to traffic: display a variety of construction signs,move the construction signs and in time according to the construction progress.
2. The construction program: marking the cracks by chalk or other material, registration station positions, measuring the length, computer material usage and costs. 3. Crack slotting :adjust the width and depth of crack router according the width and depth of cracks, cut U-shaped groove from the center line aligned cracks uniform . Usually width, depth respectively (8mm, 12mm, 10mm, 15mm, l5mm, 20mm) is appropriate. 4. Cleaning : Use the air express equipment before clean the cracks, this equipment can clear up dust and debris in order to keep the cracks and dry thoroughly, which improved the adhesion of sealant materials and pavement. It also be used for manual cleaning methods to clean the auxiliary air compressor equipment to ensure a clean fracture. 5.

Filling: crack sealing machine can be used during the filling sealant into the asphalt concrete pavement . First stirring and heating the sealant, when it reaches a certain temperature., using the slicking and pressure to pour sealant into the recess ,worse off boots with a small crack to scrape a fixed width and a T-shaped seal layer .
