Utility model content
The purpose of this utility model is to provide a kind of hot in-plant reclaimed asphalt concrete maintenance of surface structure, a large amount of waste asphalt mixtures is produced in Highway Maintenance process, by plant-mix heat recycle technology, old material is used for maintenance of surface and highway reconstruction and expansion, design a kind of maintenance of surface structure of bituminous concrete, upper basic unit, cutting optimal, middle surface layer are plant-mix recycling bituminous concrete, realize scrap loop on the one hand to utilize, improve durability, the anti-fatigue performance on road surface on the other hand, and shorten construction period.
Technical problem to be solved in the utility model realizes by the following technical solutions:
The concrete maintenance of surface structure of a kind of hot in-plant reclaimed asphalt, comprise maintenance section, this maintenance Duan Yuyuan Pavement mosaic, described former road surface comprises upper layer from top to bottom successively, middle surface layer, cutting optimal, cement treated material, it is characterized in that: the road surface of described maintenance section comprises new bituminous mixture upper layer from top to bottom successively, surface layer in hot in-plant reclaimed asphalt concrete, hot in-plant reclaimed asphalt concrete cutting optimal, basic unit on hot in-plant reclaimed asphalt concrete, heated bitumen sealing, water is surely gone to a grassroots level, in the hot in-plant reclaimed asphalt concrete of maintenance section, the middle surface layer on surface layer and former road surface splices, the hot in-plant reclaimed asphalt concrete cutting optimal of maintenance section and the cutting optimal on former road surface splice, on the hot in-plant reclaimed asphalt concrete of maintenance section, the cement treated material on basic unit and former road surface splices, the water of maintenance section is surely gone to a grassroots level and hot in-plant reclaimed asphalt concrete is spilt heated bitumen sealing between basic unit, and the new bituminous mixture upper layer of maintenance section and the upper layer on former road surface splice.
As preferably, splicing between each layer in maintenance Duan Yuyuan road surface divides step, the step width that in hot in-plant reclaimed asphalt concrete, the middle surface layer on surface layer and former road surface splices is 10-15cm, the step width that the cutting optimal on hot in-plant reclaimed asphalt concrete cutting optimal and former road surface splices is 10-15cm, and the step width that on the hot in-plant reclaimed asphalt concrete of maintenance section, the cement treated material on basic unit and former road surface splices is 15-20cm.
As preferably, described heated bitumen sealing is 0.6-1cm.
Cutting optimal gradation types in hot in-plant reclaimed asphalt concrete, in corresponding and former road surface, the gradation types of cutting optimal is identical.By the correlation test checking each layer compression rebound modulu of hot in-plant reclaimed asphalt concrete and compressive strength, and check flexural tensile stress at the bottom of this deck and whether meet code requirement, upper basic unit adopts hot in-plant reclaimed asphalt concrete.
In maintenance section hot in-plant reclaimed asphalt concrete, in surface layer and former road surface, surface layer splices, maintenance section hot in-plant reclaimed asphalt concrete cutting optimal and former road surface cutting optimal splice, maintenance section hot in-plant reclaimed asphalt concrete is gone to a grassroots level and to be spliced with former road surface cement treated material, and maintenance road section surface overlays the new bituminous mixture upper layer of one deck.Former road surface and maintenance road section surface surface layer splice a point step, and seam crossing processes according to construction cold joint, and each layer thickness of maintenance section bituminous concrete is to be as the criterion with former Pavement mosaic layer thickness.
The beneficial effects of the utility model are:
1, the utility model realizes recycling of waste asphalt mixture, and cost-saving, minimizing environment pollution, has significant economic benefit and social benefit.
2, on the utility model maintenance road section surface, basic unit adopts hot in-plant reclaimed asphalt concrete, improves the durability on road surface and effectively can prevent reflection crack.
3, the utility model can shorten construction period.
Accompanying drawing explanation
