In Vietnam, reclaimed asphalt pavement technology is considered as the key to reduce the cost of pavement construction, and decrease the industrial waste from flexible pavement rehabilitation. Ministry of Transportation has concentrated to develop RAP technology since 2008. As a result, there are three trademark of recycling technologies applied in Vietnam such as Wirtgen (Germany), Hall Brothers (U.S.), and Sakai (Japan). This paper is focused on asphalt pavement investigation of field and laboratory tests from Cold In-place recycling technology. The laboratory tests carried out on the material were conventional tests including Marshall stability, indirect tensile strength... Field data was collected using a Benkelman beam and core specimens for indirect tensile strength test.

This research bases on primary sources written in Sinograph and Nôm (vernacular Vietnamese script) by scholars in premodern Vietnam, to make a pedagogical analysis on the role of the Sanzijing (三字經) in Literary Sinitic education in premodern Vietnam. Thus, this paper claims, the study of the civil service examination in premodern Vietnam should be covered from its starting point, the primary level, to fill the gap of a partial concern by modern scholars of the high level.
