- 地基很重要。由於鋪路的地段的土質不一樣，有些松有些密造成完工以後的1-2年內出現路面的高低不平是不奇怪的。關鍵是路鋪成后的總厚度（包括路面底下的砂石）和鋪完基礎層（地基）後放置多長時間后才鋪最後的Top Layer。你有沒有注意到有些路鋪了基層以後過了幾個月才鋪最後的面層？但有些舊路翻新就不用了，因為它已經受壓多年變形穩定了。

- 練精化氣AAA: 多說一句哈， 你家那個路，如果每天有 20萬人次的流量， 一年不作維護，估計垮得更厲害well, it is possible to make it higher quality. but it would require much thicker foundation, which means much higher investment for those roads.
維護就要出錢，這才是地方政府的具體問題。
the quality of highways in the states is much lower than the that of europe, in general for two reasons: 1) there is no way to compare between highways of europe and highways of the states in terms of miles per capita (i could drive through three or even four countries in one day in europe); the investment for such long miles of highways would be incredibly huge if using european standards. 2) there is no comparison in terms of usage for those highways. at least 50% of europeans have no cars (a lot of them don't even have licenses) and largely depend on the public transportation systems.
that is why american roads always seem to be crappier, especially those segments nearby big cities.
of course, "國內人 do something for something" is also factual. the culture of quality isn't in our bone yet...
