| 摘要： | This paper presents the results of laboratory experimentation and investigation of field study of the performance of base and sub-base course constructed by using recycled Construction and Demolition Waste (CDW) for flexible pavements. The physical properties of CDW have been investigated and compared with physical properties of new materials as specified by Ministry of Road Transport & Highways, MoRTH, Government of India. The specified physical properties such as grain size distribution, specific gravity, aggregate crushing value, moisture-density relationship, abrasion value and toughness index have been evaluated by lab testing and the same have been compared with that of new materials obtained as crushed rock aggregates as per MoRTH specifications. It is observed that physical properties of recycled CDW aggregates fulfill the requirements of MoRTH Specincation. As a step forward, to investigate the effect of use of CDW as sub-base and base course, the road crust was designed as per IRC:j7:2012 and constructed as per MoRTH specification. The base course and sub-base course material was replaced by CDW material fulfilling the criteria of physical properties and gradation prescribed by MoRTH and the trial stretch of flexible pavement was constructed. The performance of flexible pavement was evaluated through field testing. The density of compacted pavement, relative density, relative compaction, plate load test of compacted pavement, bearing capacity, settlement and modulus of sub grade reaction was evaluated. The performance of the pavement has been found satisfactory from the experience of past three years. |
