|Title||Use of Reclaimed Asphalt Pavement and Demolition Debris in Road Pavement Base Layers|
|Title in Arabic||استخدام ركام الاسفلت ومخلفات الهدم في طبقات الاساس لرصف الطرق|
Using recycled material in different application means reducing costs in addition to saving environment. This research study the using of two different recycling materials which are available in Gaza with huge quantities due to political situation and construction development. These materials area demolition debris and reclaimed asphalt pavement. Many researches studied using demolition debris as base coarse aggregates, but this research added reclaimed asphalt pavement to demolition debris and for comparison to conventional aggregates in different ratios 10%, 20%, 30%, 40% and 50%. For studying the properties of these mixtures, Sieve analysis, Specific gravity and absorption, Atterberg limits, Los Angeles abrasion test, Sand equivalent, Proctor compaction, California bearing ratio, and Bitumen extraction of reclaimed asphalt pavement were performed. Results showed that some properties is improved with adding reclaimed asphalt pavement as Los Angeles value, Sand equivalent and Absorption, but other properties decreased specially California bearing ratio. Sieve analysis illustrates that particles with gradation greater than 50mm have to be removed from reclaimed asphalt pavement. It is recommended that the maximum content of reclaimed asphalt pavement in demolition debris must not be greater than 40%. But 50% content of reclaimed asphalt pavement in conventional material is valid for Gaza strip condition.
