And secondly, the quantity of the mixture to be filled when the inspection well cover is lowered to the bottom is not measured. Usually, a mixture is manually filled under the well lid by using a shovel, and the well lid is 1-2cm higher than the surrounding pre-pressing surface after the mixture is fully filled, but the height can only be determined by feeling due to different thicknesses of the upper, middle and lower surface layers. The upper surface layer is designed to have the thickness of 4cm, if the well lid is 1-2cm higher than the surrounding asphalt surface, the well lid is higher than the surrounding asphalt surface after the rolling is completed, the flatness is influenced, and if the well lid is strongly vibrated to be leveled, the mixture can be shattered, so that the bearing capacity of the well lid is reduced; the well cover at the middle and lower layers is higher than 1-2cm, because the mixture is turned over, the compaction coefficient is different from that of the mixture pre-pressed at the periphery, and the mixture under the well cover is not enough in compaction degree after the disturbed mixture is filled and rolled. The above reasons can cause the insufficient intensity of the asphalt mixture under the well cover or around the well cover, and the bearing capacity is reduced.
