Description
Technical field
The present invention relates to the job practices of flexible pavement, particularly interlamination processing method for high grade road asphalt road surface.
Background technology
The high-grade highway flexible pavement is made up of two-layer or three layers of asphalt concrete pavement, because the road surface is the layering making, so interlayer slip is one of common disease in the actual use.Interlayer slip is meant when adhesion strength between surface layer and surface layer and shear strength are not enough, under the effect of driving horizontal force, produces slippage between upper and lower two surface layers, and produces on the road surface and pass the phenomenon of gathering around pavement diseases such as bag.Existing flexible pavement interlayer processing method is the flexible pavement that layering is paved, and carries out interlaminar bonding in the mode of spraying sticking layer oil between its layer and layer, and then realizes totally continuous integral body.Promptly after the intact substratum health of making finishes, spray one deck sticking layer oil, and then making one deck surface layer, sticking layer oil plays topmost interconnect function as main interlaminar bonding means.But in practice of construction, because the situation of material, spray application and the practice of construction of sticking layer oil is complicated and changeable, often bond effect is undesirable, especially to some long, big longitudinal gradients, bend, curved bridge and the serious highway section of overload phenomenon, the shearing force of interlayer is bigger, and the cementation of sticking layer oil is limited, interlayer slip therefore often occurs, early diseases such as bag appear passing, gather around in the road surface, influence the normal use on road surface.
Summary of the invention
Problem to be solved by this invention provides a kind of interlamination processing method for high grade road asphalt road surface that can effectively prevent interlayer slip.
The technical scheme that addresses the above problem is that the interlamination processing method for high grade road asphalt road surface that is provided may further comprise the steps:
1, the intact substratum of making forms convex-concave surface with mechanical means on substratum;
2, repave after finishing and build the new asphalt surface course of one deck;
3, the number of plies of laying is as requested carried out multilayer pouring by above-mentioned steps 1,2, finishes until paving.
Adhesion stress between further enhancement layer can impose sticking layer oil on the above-mentioned substratum with convex-concave surface behind completing steps 1, form one deck tack coat, treats to repave on tack coat after health finishes and builds the new asphalt surface course of one deck.
Above-mentioned formation convex-concave surface can be to adopt milling roller with convex-concave surface or rolled plate to roll on substratum and form convex-concave surface; Also can form convex-concave surface with plane, the mode of milling.
When employing has the milling roller of convex-concave surface or rolled plate when rolling on substratum, the temperature of substratum bituminous mixture is preferably in 90～150 ℃, its degree of compaction is 80%～95%, so not only can roll easily, reach the requirement of male and fomale(M﹠F), nor can influence the structure and the performance of substratum.
Above-mentioned formation convex-concave surface can be elder generation's hard material piece such as spreading rubble or concrete precast block on substratum, partly embeds in the substratum by rolling hard material pieces such as making rubble or concrete precast block then, thereby forms convex-concave surface.With the mode of rolling in like manner, by rolling hard material pieces such as making rubble or concrete precast block when partly embedding substratum, the temperature of substratum bituminous mixture is preferably in 90～150 ℃, its degree of compaction is 80%～95%.
Above-mentioned convex-concave surface is from overlooking direction, can be continuous strip or interrupted strip groove from the end to end on road surface.Can be a kind of in vertical element, curved line or the broken line bar groove, or the meshed grooves that intersects to form by vertical element, curved line.
The vertical profile profile of above-mentioned convex-concave surface groove can be by a kind of formed tooth profile in triangle, square, trapezoidal, irregular polygon or circular arc etc., also can be the tooth profile of other shape.
Compared with prior art, because the surface of asphalt surface course is rough shape, during the asphalt surface course that paves new on rough substratum, the bituminous mixture that newly paves can embed in the groove, roll end after, form the structure of mutual interlock between two-layer; If impose sticking oil reservoir, then increased the contact area of sticking layer oil, thereby strengthened adhesion stress.The effect of these measures is the skid resistances that increased interlayer, has played the effect of opposing shear stress, has significantly improved the bonding degree of interlayer, thereby has stoped the generation of interlayer slip effectively.
