Open general seal road surface structure

The utility model belongs to the technical field of road engineering, particularly, involve an open general seal road surface structure. Road surface structure from the bottom up has laid the basic unit in proper order, emulsified asphalt passes through layer, rubberized asphalt chip seal, SBS modified asphalt chip seal and little table department layer. Compared with the prior art, open general seal road surface structure has following characteristics: 1 )This road surface structure adopts the combination on two -layer chip seal and little table department layer, can restrain the fissured reflection of bituminous paving well, increase of service life, and most of road surfaces of highway and state's provincial highway can be applied to to this technique, 2 )The shop layer is relatively more pleasing to the eye, coefficient of friction is high, the non -skid property good, 3 )Adopt rubberized asphalt, SBS modified asphalt as chip seal's bond, can play the fine water effect of sealing, improve the wholeness ab
