Expressway anti-scouring roadbed pavement and construction method
The invention discloses an expressway anti-scouring roadbed pavement which comprises a broken stone hardcore, an lime-soil layer, a cement stabilized macadam layer, an asphalt layer, protection slopesand back pressure protection channels; the lime-soil layer is arranged at the upper end of the broken stone hardcore; the cement stabilized macadam layer is arranged at the upper end of the lime-soillayer; the asphalt layer is arranged at the upper end of the cement stabilized macadam layer; the protection slopes are arranged on the two sides of the broken stone hardcore, the ash soil layer andthe cement stabilized macadam layer; a back pressure protection channel is arranged on the outer side of each protection slope; the lime-soil layer comprise a first lime-soil layer, a second lime-soillayer and a third lime-soil layer, the first lime-soil layer is arranged on the broken stone hardcore, the second lime-soil layer is arranged on the first lime-soil layer, and the third lime-soil layer is arranged on the second lime-soil layer. By arranging the broken stone hardcore, the protection slopes and the back pressure protection channels, the problems that an existing expressway subgradeand pavement is poor in stability and prone to local collapse due to rain wash, and great hidden dangers are brought to driving are solved.
本发明公开了一种高速公路防冲刷路基路面，包括碎石垫层、灰土层、水泥稳定碎石层、沥青层、护坡和反压护道，所述碎石垫层的上端设置有灰土层，所示灰土层的上端设置有水泥稳定碎石层，所述水泥稳定碎石层的上端设置有沥青层，所述碎石垫层、灰土层和水泥稳定碎石层的两侧设置有护坡，所述护坡的外侧设置有反压护道，所述灰土层包括第一灰土层、第二灰土层和第三灰土层，所述第一灰土层设置在碎石垫层上，所述第二灰土层设置在第一灰土层上，所述第三灰土层设置在第二灰土层上。本发明通过设置碎石垫层、护坡和反压护道，解决了现有的高速公路路基路面稳定性差，容易受到雨水冲刷而局部塌陷，为行车带来较大隐患的问题。
