Description
Technical field
This utility model relates to a kind of bituminous paving, particularly relates to a kind of bituminous paving with cracking resistance and fracture resistance.
Background technology
Bituminous paving occurs that crack and folding line can cause vehicle vibration, affects traffic safety and road-ability.Therefore, thus carry out the control of Asphalt Pavement Surface Evenness, be one of the important content of highway engineering quality management.In recent years, China's road construction cause is fast-developing, motor-driven recoverable amount cumulative year after year, highroad pavement planeness is proposed the highest requirement, constantly increases at vehicle flowrate, under the background that road construction scale expands further, ensure surface evenness, become minimizing roadbed, pavement disease occurs, and extends highway engineering service life, improves the important channel of investments in highway building income.
Utility model content
The purpose of this utility model is to provide a kind of bituminous paving with cracking resistance and fracture resistance, and this bituminous paving road has higher elasticity and toughness, has the highest traffic safety and road-ability.
To achieve these goals, the technical solution of the utility model is:
A kind of bituminous paving with cracking resistance and fracture resistance, includes upper layer, cutting optimal, basic unit, underlayment and bed course from top to bottom；Described upper layer is modified stone mastic asphalt mixture pavement, and upper layer thickness is more than 20cm；Described cutting optimal is particulate formula asphalt concrete layer；Described basic unit's inner transverse is uniformly arranged concrete reinforced pipe, and the described spacing between concrete reinforced pipe is 50m；Described underlayment is middle grain formula asphalt concrete layer；Described bed course is brick and tile rubble；The both sides of described basic unit are respectively provided with baffle plate, and described baffle plate is the plate of cross section parallelogram, and the height of baffle plate is equal to basic unit, cutting optimal and the height sum of upper layer；The bottom of baffle plate arranges reinforcement, and described reinforcement is triangular in shape.
Further, between described upper layer and cutting optimal, rubber spacer is set.
Further, described upper layer thickness is 30cm.
Further, described concrete reinforced pipe is flat mouth concrete reinforced pipe for building.
Further, described baffle plate is steel plate.
The beneficial effects of the utility model are:
By a kind of bituminous paving with cracking resistance and fracture resistance that the utility model proposes, because modified stone mastic asphalt compound has the most high temperature resistant, anti-seismic design, there is preferable rutting resistance, improve the anti-fatigue ability on road surface, particularly on big flow, the serious highway that overloads, there is good adaptability to changes, the permanent deformation on road surface can be reduced；Rubber spacer is set between upper layer and cutting optimal, makes road surface have higher elasticity and toughness, strengthen traffic safety and road-ability；When Colophonium thickness is more than 20cm, it is possible to effectively reduce the appearance in crack and extend the life-span of Colophonium；The brick and tile rubble of bed course had both achieved the cyclic utilization of waste, and its drainage performance is good；Basic unit's inner homogeneous arranges concrete reinforced pipe, and construction in later period wiring need not demolish road surface；Both sides, road surface arrange baffle plate and can effectively prevent the asphaltic road-mix surface course passage under horizontal loads caused by shearing strength deficiency from gathering around bag.
