Abstract
The invention discloses a process for quickly repairing semi-rigid substrate damage of an asphalt pavement, which comprises the following steps: milling and planing an asphalt topping and a loose substrate at normal temperature, leveling a roadbed, spreading gravels having a thickness of 10-20cm, spreading large stone asphalt mixtures of 25-40cm at twice, paving glass fiber grids, spreading coarse graded asphalt, cooling before opening to traffic for 2-3 days, and finally spreading topping asphalt concrete, thus finishing the quick repair of the semi-rigid substrate damage of an asphalt pavement. The invention can resist high plastic and shear deformation and bear heavy-duty traffic action, has fine rutting resistance, improves the high-temperature stability and water stability of the asphalt pavement, and has fine drainability; the on-site construction process is simple and feasible, and the operation time is short; the reflection crack resistance and pavement deformation resistance of the pavement are improved; the bonding property with the asphalt topping is fine, and the pavement structure can be stressed more evenly, thereby having high lasting quality; and by increasing large stone aggregate and reducing powdered ore, the construction cost is lowered.
Description
Technical field
The present invention relates to urban road maintenance field, relate in particular to the damaged repair technology fast of a kind of flexible pavement semi-rigid type base.
Background technology
China's urban road great majority adopt flexible pavement at present, and owing to construction technology, economic cause, semi-rigid asphalt pavement is to have built flexible pavement primary structure form.Yet, semi-rigid material easily produces shrinkage crack and thermal cracking, because the existence in crack, passage is provided for the water intrusion roadbed, the outward appearance of serious bad road pavement of damage by water and durability produce very big influence, the functional performance on road surface also reduces greatly, the increase of the heavily loaded traffic volume in recent years in addition, and the problem of semi-rigid type base asphalt concrete pavement non-deformability deficiency has highlighted.After operation a period of time, just must be transformed, with recover its original function of use, especially after early stage damage appears in the road surface, just must overlay one deck again.Semi-rigid type base is damaged maintenance generally adopt empirical operating type, need long sealing conditioned time, preserving period generally is no less than 7d, for the quickening progress does not influence traffic, in base mixture, mix early strength admixture, health is just done surface layer less than 7d, causes foundation base intension not reach and requires and the generation cracking.
Summary of the invention
Problems such as purpose of the present invention is subjected to the restriction of urban traffic condition big for solving the damaged repair technology defective of existing semi-rigid type base, and repairing quality does not reach code requirement, and curing time is long provide a kind of flexible pavement semi-rigid type base damaged repair technology fast.
The damaged technique for rapidly repairing of flexible pavement semi-rigid type base is: the loose basic unit of milling asphalt surface course and milling at normal temperatures, the roadbed leveling, the thick rubble of the 10cm～20cm that paves, 25cm～40cm LSAM then at twice paves, lay glass fiber grid, the coarse grain formula that paves pitch, cooling back open to traffic 2～3 days, the surface layer bituminous concrete that paves is at last finished the quick reparation of flexible pavement semi-rigid type base breakage;
The described rubble that paves adopts thickness to be preferably 10cm～15cm.Described LSAM adopts thickness to be preferably 25cm～35cm.
The present invention's beneficial effect compared with prior art is:
1, can resist bigger plasticity and the distortion of cutting property, bear heavily loaded traffic effect, have good rutting resistance, improve the high-temperature stability and the water stability of flexible pavement;
2, void content is bigger, and good drainage performance is arranged, and can have the function of surface drainage layer concurrently;
3, site construction technology is simple and easy to do, the activity duration short (construction in evening, daytime open to traffic);
4, improved the ability of antireflection crack, road surface and surface deformation;
5, bond well with asphalt surface course, guaranteed the continuity of structure, road structure is stressed more even, the endurance quality height;
6, big particle diameter gathers materials increases minimizing with the breeze consumption, has reduced specific area, has reduced asphalt content, has reduced construction costs.
The specific embodiment
The damaged technique for rapidly repairing of flexible pavement semi-rigid type base is: the loose basic unit of milling asphalt surface course and milling at normal temperatures, the roadbed leveling, the thick rubble of the 10cm～20cm that paves, 25cm～40cm LSAM then at twice paves, lay glass fiber grid, the coarse grain formula that paves pitch, cooling back open to traffic 2～3 days, the surface layer bituminous concrete that paves is at last finished the quick reparation of flexible pavement semi-rigid type base breakage;
The described rubble that paves adopts thickness to be preferably 10cm～15cm.Described LSAM adopts thickness to be preferably 25cm～35cm.
Embodiment 1
Certain city subsidiary road groundwork thickness is 40cm, and the road surface crack failure is serious.The loose basic unit of milling asphalt surface course and milling at normal temperatures, the roadbed leveling, the thick rubble of the 10cm that paves, the 30cm LSAM that paves is at twice then laid glass fiber grid, the coarse grain formula that paves pitch, open to traffic 2 days, the surface layer bituminous concrete that paves is at last finished the quick reparation of flexible pavement semi-rigid type base breakage, uses after 3 years the intact nothing in present situation road surface damaged.
Embodiment 2
Certain major urban arterial highway groundwork thickness is 45cm, and the road surface crack failure is serious, and deflection value is 1.14mm after testing.The loose basic unit of milling asphalt surface course and milling at normal temperatures, the roadbed leveling, the thick rubble of the 10cm that paves, the 35cm LSAM that paves is at twice then laid glass fiber grid, the coarse grain formula that paves pitch, open to traffic 3 days, the surface layer bituminous concrete that paves is at last finished the quick reparation of flexible pavement semi-rigid type base breakage, through detecting deflection value once more is 0.34mm, satisfies code requirement.
Claims (3)
1. the damaged technique for rapidly repairing of a flexible pavement semi-rigid type base, it is characterized in that: the loose basic unit of milling asphalt surface course and milling at normal temperatures, the roadbed leveling, the thick rubble of the 10cm～20cm that paves, the 25cm～40cm LSAM that paves is at twice then laid glass fiber grid, the coarse grain formula that paves pitch, cooling back open to traffic 2～3 days, the surface layer bituminous concrete that paves is at last finished the quick reparation of flexible pavement semi-rigid type base breakage.
2. the damaged technique for rapidly repairing of a kind of flexible pavement semi-rigid type base according to claim 1 is characterized in that: it is 10cm～15cm that the described rubble that paves adopts thickness.
