Without a strong and stable subgrade there is no stable pavement.
沒(méi)有堅(jiān)固、穩(wěn)定的路基就沒(méi)有穩(wěn)固的路面。
Meanwhile, some measures of improving evenness of subgrade and pavement structures are presented basing on design and construction.
同時(shí)提出了從設(shè)計(jì)和施工兩方面提高路基和路面結(jié)構(gòu)層均勻性的一些措施。
The strength and stability of subgrade not only should be ensured through the good design, and can be realized through the construction.
路基的強(qiáng)度和穩(wěn)定性，不僅要通過(guò)好的設(shè)計(jì)予以保證，而且要通過(guò)施工得以實(shí)現(xiàn)。
