Abstract
This paper analyses the strength and stress-strain behaviour of construction and demolition wastes (CDW) to obtain parameters for pavement design, using large cylindrical specimens (25â¯Ãâ¯50â¯cm). Though CDW friction angle (41°) is lower than that of densely graded crushed basalt, its cohesion (136â¯kPa), Poisson's ratio (0.38) and resilient response are quite similar. Permanent strain test results indicate that in pavement layers with Ïd/Ï3â¯<â¯2 and Ïdâ¯â¤â¯210â¯kPa, CDW will respond nearly elastically and be safe against rutting. Therefore, CDW may be used in bases of low to medium traffic volume urban pavements, managing wastes whose generation continuously increases.
