主要是有幾個原因混在一起造成柏油路坑洞的情況:
一般因為是因為交通流量大,行車速度快,又常有大型車開來開去,
造成對於路面的剪應力,讓路面龜裂。
再來是長期高溫曝曬,那裏面瀝青與小石礫的膨脹比例不同,
夜晚降溫的時候,收縮比例又不一樣,長期下來會在瀝青與小石礫膠結造成孔隙,
那大雨一來,沖刷幾次,就產生坑洞拉。
再加上,只要當初施工的廠商偷工減料,比如說瀝青減量,鋪石的壓密度不足,
或是被惡劣廠商參雜一些廢棄物的碎屑爐灰之類的鬼,造成膠結力大大的不足,
就會很容易在大雨沖刷下產生坑洞。
高雄氣候熱,大型車的來往也頻繁,加上我想台灣工程承包商偷工減料的情況也很常見,
因此除了花大量的人力物力固定時間維護道路補洞,不然坑洞一定是遲早會產生的。
※ 引述《Rita0205 (姆咪榨豆漿)》之銘言:
: 安安大家午安
: 剛剛出門買咖啡豆的時候
: 開在大順路、自由路上
: 發現馬路上的坑洞有點多欸
: 幾乎每隔一、兩個路口就有一個坑
: 是說最近高雄下個雨,就一堆坑洞是在…?
: 而且坑洞旁還一堆小石子
: 開車都要一直閃不壓坑
: 而且有些坑洞還都是水,很難注意
: 騎摩托車的更要小心欸
: 下大雨開車我就不附照片了
