摘要
非洲国家刚果(金)地处赤道附近,属热带气候,一年分旱雨两季。旱季滴雨不见,雨季暴雨倾盆。新修的卢卡公路采用沥青路面、透层、4%水泥稳定砾粒土基层(在原老路基上铣刨),然而沥青路面经过一个雨季后却易出现早期损害现象,水损害是其中首要的也是最严重的现象之一。在对路面破坏现象细致调查上通过反复分析、论证发现,沥青路面的早期破坏现象与水有关。
African countries of Congo （DRC） is located near the equator, has a tropical climate, one-year sub-wet and dry seasons. Not seen a drop of rain during the dry season, the rainy season torrential rain. Newly built roads in Lucca, using bituminous road surface 、transparent layer、4% cement stabilized gravel soil primary particles （in the old roadbed on the original milling）, but the asphalt pavement over an easy to occur after the rainy season but the phenomenon of early damage, water damage is one of the primary is also one of the most serious phenomena. In detailed investigations on the phenomenon of road damage through repeated analysis, demonstration found that the early failure phenomena of asphalt pavement with water-related.
