Publikováno v: JOURNAL OF PAVEMENT ENGINEERING, JSCE. 4:209-214
In composite pavements, such as whitetopping and overlay, it is important to ensure the bond between asphalt layer and concrete layer for long-term performance of the pavements. The bond strength is expected to be influenced by characteristics or tex

STUDY ON DESIGN FACTOR OF ASPHALT MIXTURE CONSIDERING AGGREGATE VOIDS
Autor: Koichi Ozawa, Masashi Koyanagawa, Shuichi Kokubun
Publikováno v: JOURNAL OF PAVEMENT ENGINEERING, JSCE. 3:217-224
It is well known that characteristics of asphalt mixture are influenced by quantity of asphalt mortar and filler bitumen. The use of the special mixture increases at present as much as the continuously graded mixture. The method of mix design describ
