Pavement binder loses the binding force and looses the aggregate. When the area is more than 0.1m2, it becomes loose on the road. In this case, the pavement must be repaired, otherwise it will affect the traffic and pedestrian safety of the road. There are many reasons for the looseness of the road surface. Find the most appropriate solution for different reasons. The general process to solve the looseness of the road surface is to use emulsified asphalt to pour a layer on the road surface, and then evenly spray on the emulsified asphalt with dry stone powder, and then use a broom to sweep evenly or use a rubber roller to spray the water without roller. After drying thoroughly, use a blower to blow away the remnants of the stone powder. This is a conventional solution, but if the road surface is due to a poor combination of the surface layer and the base layer, or because of improper peeling due to improper maintenance, the clean and loose parts should be removed first, and then the adhesive layer asphalt should be sprayed. Resurfacing. Poor adhesion between asphalt and acid stone will also cause loose looseness. At this time, loose parts should be removed first. Alkaline stone or acid stone should be used as mineral material, and tackifier or slaked lime or cement should be used as part of the filler. Greatly improve the adhesion of bitumen and minerals and the water stability of the mixture, and then resurface the pavement. Another possible reason for removing loose parts during the construction process is that the looseness of the road surface is caused by the loss of cohesion due to aging of the asphalt due to the high oil temperature. If the long-term base soil or base layer gradually softens and deforms, such a situation needs to be dealt with after the damaged soil base or base layer is used again. Different reasons will lead to loose roads. It is necessary to find out the root cause of the looseness of the road surface and solve the problems in a timely manner so as to ensure the good condition of the road surface.
