Stone mastic asphalt (SMA) pavement construction method
The invention provides a stone mastic asphalt (SMA) pavement construction method. The method comprises the following steps of determining mineral aggregate gradation and the optimal asphalt-aggregate ratio of SMA raw materials, carrying out bonding construction on a lower bearing layer, mixing the SMA raw materials, wherein an asphalt heating temperature is in a range of 170-180 DEG C, an aggregate heating temperature is in a range of 185-195 DEG C and a discharging temperature is in a range of 175-185 DEG C, spreading the materials, wherein a factory temperature is in a range of 170-185 DEG C, an attendance temperature is greater than or equal to 170 DEG C and a spreading temperature is greater than or equal to 170 DEG C, carrying out rolling compaction by primary rolling compaction, secondary rolling compaction and final rolling compaction, wherein a primary rolling compaction temperature is greater than or equal to 160 DEG C, a secondary rolling compaction temperature is greater than or equal to 140 DEG C and the final rolling compaction is greater than or equal to 120 DEG C, and opening to traffic when the pavement temperature is less than 50 DEG C. The method realizes temperature control from stirring to rolling compaction and eliminates temperature influence on construction.
