病害描述 Description 在刹车、转弯、加速路段出现的的 U 型开裂
U-shaped cracks in areas of braking, turning, accelerating. 可能的原因 Possible Causes

病害处治 Cures局部修补 Localized patching
表面变形 Surface Deformation
类型 Types
车辙 Rutting
推挤 / 拥包 Shoving and Corrugation
车辙 Rutting
车辙 Rutting 可能的原因 Possible Causes
施工过程中沥青混合料压实不足 Insufficient compaction of HMA layers during construction. (If it is
not compacted enough initially, HMA pavement may continue to densify under traffic loads.)
路面承载不足致使路基出现车辙 Subgrade rutting (e.g., as a result of inadequate pavement
structure) 沥青混合料设计或生产不正确 (如沥青含量过高、粉料过多、规则集料量不足) Improper mix design or manufacture (e.g.,
excessively high asphalt content, excessive mineral filler, insufficient amount of angular aggregate particles)
车辙 Rutting 病害处治 Cures
局部修补 Localized patching
微表处 Micro Surfacing
热拌沥青混合料薄层罩面 Thin hot-mix overlay
推挤 / 拥包 Shoving and Corrugation
可能的原因 Possible Causes 不稳定的沥青混合料层 An unstable (i.e. low stiffness) HMA layer (caused by
mix contamination, poor mix design, poor HMA manufacturing, or lack of aeration of liquid asphalt emulsions)
路基湿度过大 Excessive moisture in the subgrade 层间移动滑移 Slippage between layers
推挤 / 拥包 Shoving and Corrugation
病害处治 Cures
局部修补 ( 挖除和填补 ) Localized patching ( Remove
the distorted pavement and patch ) 铣刨和重铺 Milling and Overlay ( Remove the
damaged pavement and overlay )
推挤 / 拥包 Shoving and Corrugation
表面缺陷 Surface Defects
类型 Types
泛油 Bleeding
骨料磨光 Polished Aggregate
松散 Raveling
泛油 Bleeding
泛油 Bleeding 可能的原因 Possible Causes
沥青混合料沥青含量过高 ( 沥青混凝土路面) Excessive asphalt binder in the HMA (either due to mix
design or manufacturing) 沥青洒布量过大 (沥青表处路面) Excessive application of asphalt binder during BST
application 沥青混合料孔隙率过低 Low HMA air void content (e.g., not enough room for
the asphalt to expand into during hot weather)
泛油 Bleeding
病害处治 Cures
碎石封层 Seal coat or Double chip seal
稀浆封层 Slurry seal
微表处 Micro Surfacing
热拌沥青混合料薄层罩面 Thin hot-mix overlay

骨料磨光 Polished Aggregate
可能的原因 Possible Causes 软骨料 Soft aggregate 重载交通 Heavy traffic
病害处治 Cures
碎石封层 Seal coat or Double chip seal
稀浆封层 Slurry seal
微表处 Micro Surfacing
热拌沥青混合料薄层罩面 Thin hot-mix overlay
松散 Raveling
松散 Raveling
可能的原因 Possible Causes 骨料颗粒和沥青之间缺乏粘结力(原因:骨料含尘量大、骨料离析、施工过程中压实不够) Loss of bond between aggregate particles and the
asphalt binder as a result of: A dust coating on the aggregate particles that forces the
asphalt binder to bond with the dust rather than the aggregate.
Aggregate Segregation. Inadequate compaction during construction.
松散 Raveling

pavement and patch)
