Technical field
This utility model relates to highway construction field, is specifically related to a kind of compound resistance to compression roadbed.
Background technology
Raising along with people's living standard, private vehicle also gets more and more, and as the road of vehicle pass-through, when life-time service, owing to road surface compressive resistance is limited, road surface is often made to produce and cracking phenomena, need to be by repeatedly keeping in repair in using, extend the service life on road surface, waste a large amount of manpower financial capacity during maintenance, still can not meet road surface resistance to compression demand.
Utility model content
The purpose of this utility model is that provides a kind of compound resistance to compression roadbed to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of compound resistance to compression roadbed, including soil matrix layer, composite concrete mortar and steel reinforcement cage, described soil matrix layer is provided above with soil stone bed course, described soil stone bed course is arranged above with the permeable underlayment of grittiness, the permeable underlayment of described gravel is provided above with lime-fly ash aggregate base, described lime-fly ash aggregate base is provided above with described composite concrete mortar, described composite concrete mortar is internally provided with described steel reinforcement cage, described steel reinforcement cage is provided above with resistance to compression steel bar, and described composite concrete mortar is provided above with asphalt macadam surface layer.
In said structure, the permeable underlayment of described gravel is possible not only to permeable, increase comprcssive strength simultaneously, described lime-fly ash aggregate base makes described composite concrete mortar when cast, bottom does not subsides, and described steel reinforcement cage greatly strengthen the comprcssive strength of described composite concrete mortar, described resistance to compression steel bar is welded in described surface of reinforcing cage simultaneously, increase the compression area of described steel reinforcement cage, improve the comprcssive strength of described steel reinforcement cage.
In order to improve the using effect of a kind of compound resistance to compression roadbed further, described soil stone bed course is layered on above described soil matrix layer, and the permeable underlayment of described gravel is layered on above described soil stone bed course.
In order to improve the using effect of a kind of compound resistance to compression roadbed further, described lime-fly ash aggregate base is layered on above the permeable underlayment of described gravel, and described composite concrete mortar waters and is filled in above described lime-fly ash aggregate base.
In order to improve the using effect of a kind of compound resistance to compression roadbed further, described resistance to compression steel bar is welded in above described steel reinforcement cage, and described steel reinforcement cage is embedded in inside described composite concrete mortar.
