Influence of Aggregates on Stripping Behavior of Bituminous Mixes

Moisture damage leads to premature failure of flexible pavements. The removal bituminous coating from aggregates lead the disintegration mixes and is known as stripping. Various mechanisms factors have been identified play a role in process, properties being one major factors. This study an attempt analyze influence chemical, mineralogical physical on stripping propensity loose mix. For this purpose, are chosen six different quarry sites with diverse chemical compositions used for construction maintenance large network roads. Stripping tests thereafter conducted using percentage hydrated lime. amount lime required prevention concerned aggregate sources determined. research findings that presence elements such silicon potassium decrease bond strength whereas calcium, sodium, iron, magnesium aluminium enhanced strength. Statistical tools techniques verify results. Comparatively softer showed lesser resistance which could be inferred impact Los Angeles abrasion tests. can helpful selection content road depending upon sensitivity Doi: 10.28991/cej-2021-03091671 Full Text: PDF
