Description
Technical field
The application relates to a kind of hard and soft composite construction road surface.
Background technology
China's highway construction road structure design at present is divided into two kinds of rigid pavement and flexible pavements, it be the basis that Flexible Pavement Design adopts elastic system theory, and structure design serves as that basic employing road shows to allow that rebound deflection allows flexural tensile stress and three design objectives of allowable shearing stress with the three layer elastic system theory under the uniform vertical and horizontal loads of two circles.(People's Republic of China's industry standard " urban road design specifications " CJJ37-90).Flexible pavement road bearing course is a roadbase, and basic unit is divided into the pellet class (interlocking type and grating type) (People's Republic of China's industry standard " asphalt highway design specifications " JTJB50-2006) that has binder to stablize class (organic binder and inorganic binder) and no binder.Above-mentioned standard flexible pavement road structure design, on elastic body theoretical foundation, road structure basic unit (flexbile base, rigid base, semi-rigid type base) all adopts according to overall structure and designs.Be the plane layer stack structure between the road structure layer.
In present domestic road construction, adopting this half rigid structure using it as road base of cement stabilized macadam is main flow.But there is following technological deficiency in the cement stabilized macadam semirigid structure:
1, because the temperature influence of expanding with heat and contract with cold, the thermal cracking that cement stabilized macadam base produces can not be avoided, and the reflection crack that flexible pavement is caused has become one of main factor that influences road application life.
2, because the cement stabilized macadam structure is the minimizing shrinkage crack, cement consumption is subjected to strict restriction (below 6%), make that this structural strength low (speedway design 3.5MPa) shock resistance fatigue capability is not strong, roadbed well damage under the repeated stock of road heavy-duty vehicle becomes one of main factor of China's road damage.
3, cement stabilized macadam structure, can not show a candle to external road and use average life span basically at 5--8 road application life of causing the heavy duty traffic of present China.
Abroad at this problem, begin design in the eighties in last century and use complete thick formula long-life road surface, road structure all adopts flexible asphalt pavement structure, but the highway construction expense is very high, is unsuitable for promoting the use of in China's large tracts of land.
