车辙产生机理及分类
1车辙的产生机理
沥青混凝土路面开放交通之后,在行车荷载反复作用下,车辙的形成可分为三个阶段：
（1）开始阶段的压密过程：经碾压,高温下处于半流动状态的沥青及沥青与矿粉组成的胶浆被挤进矿料之间,同时集料被强力排成具有一定骨架的结构.碾压完毕交付使用后,此压密过程还会进一步发展.
（2）沥青混合料的流动：高温下的沥青混合料成为以粘性为主的半固体,在轮胎荷载作用下,沥青及沥青胶浆便开始流动,路面受载处被压缩而变形.
（3）矿质骨料的重排及矿质骨架的破坏：高温下处于半固态的沥青混合料,由于沥青及沥青胶浆在荷载作用下首先流动,混合料中粗、细集料组成的骨架在荷载直接作用下,沿矿料间接触面滑动,促使沥青及胶浆向富集区流动,以至流向混合料自由面.
由此可见,车辙形成的最初原因是压密及沥青高温下的流动,最后导致骨架的失稳,从本质上讲就是沥青混合料的结构特征发生了变化.
根据车辙成因不同,车辙可分为以下五种类型：
（1） 结构型车辙：由路面基层及路基变形引起,这种车辙的宽度较大,两侧没有隆起现象,横断面呈U字型.
（2）失稳型车辙：在高温条件下,由于荷载的反复作用,荷载应力超过沥青混合料所能承受的稳定性应力极限,发生流动变形不断累积形成的车辙.其特点是两侧伴有隆起现象,内外侧呈非对称形状,横断面呈W型.
（3）磨耗型车辙：由于沥青路面顶层的材料在车轮磨耗和自然环境因素下持续不断地损失形成,尤其是冬季埋钉轮胎形成的磨损性车辙.
（4）压密型车辙：由于沥青路混合料进一步被压密引起的,这种车辙的特点是只在轮迹下,也呈V字或W型,但两侧没有隆起,车辙的形成在初期发展很快.这是一种非正常的车辙,其原因是施工时压实度不足,致使通车后的第一个高温季节混合料被继续压密,进而形成明显的车辙.
（5）水损害型车辙：由于沥青混凝士的中下层产生明显的水损害而失去了沥青膜的粘结作用,从而在荷载的作用下出现了因变形累积而形成的车辙.
我国的高等级道路沥青路面基层大多采用半刚性基层,强度高、板整体性好,基层及基层以下的变形极小,沥青面层产生的车辙深度占路面总车辙深度的90％以上.
回答还行，有没有更准确的答案啊

Rut formation mechanism and classification of
1 track of the generation mechanism
Asphalt Concrete Pavement open traffic after the traffic load under repeated,the formation of track can be divided into three phases:
(1) the initial stage of the compaction process:by the RCC,high temperature and in a semi-flowing state of asphalt and asphalt cement with slag was composed of mineral aggregate into between the aggregate at the same time was a strong line up has a certain frame structure.RCC completed after delivery,the compaction process will be further developed.
(2) the flow of asphalt mixtures:a high temperature of the asphalt mixture into a viscous-based semi-solid,in the tire load,bitumen and asphalt cement began to flow,the road is to be set by the compression and deformation.
(3) of mineral aggregate and mineral skeleton rearrangement damage:high temperature in a semi-solid mixture of asphalt,as asphalt and asphalt cement in the first movement of loads,Mixture thick,composed of fine aggregate skeleton directly under the load along the contact surface between the mineral aggregate sliding to asphalt and cement-rich region to the movement and mixture of free surface flows.
This shows that the rut because of the formation of the initial compaction and asphalt at high temperatures the flow,and finally lead to instability of the skeleton,in essence,is the asphalt mixture's structural characteristics have changed.
According to different causes rutting,rutting can be divided into the following five types:
(1) structure-type track:from the road surface and roadbed deformation caused by the grass-roots level,the larger the width of track,both sides do not bulge phenomenon was U-shaped cross section.
(2) instability type rut:at high temperature conditions,due to repeated load role,load stress over asphalt mixture can bear the stress limits of stability,the occurrence of the flow deformation has accumulated to form the track.It features both sides of the uplift associated with the phenomenon,which was non-symmetrical shape of the lateral,cross-sectional showed W-type.
(3) Wear-type Rutting:Asphalt Pavement as a result of top-level material in the wheel wear and the natural environment factors continuing loss of form,especially in the winter buried nails wear formed tire rut.
(4) compaction-type rut:as a result of asphalt mixture was further caused by compaction,which is characterized by rut only in the next round of track,also on the V-or W-type,but both sides do not bulge,the formation of ruts in the initial stage of rapid development.This is a non-normal track,the reason is that during the construction of less than degree of compaction,with the result that after the opening of the first season of high-temperature mixture was continued to compaction,thereby forming a clear track.
(5) Water damage type Rutting:Asphalt Concrete as a result of the lower and middle classes of significant water damage and loss of asphalt adhesive membrane,thus the role of the load due to deformation under the accumulated rut formed.
China's high-grade road asphalt pavement mostly grass-roots adoption of semi-rigid,high strength,good board overall,the grass roots and grass-roots following the deformation is extremely small,asphalt surface rut depth resulting from the total of off-road rut depth of 90%.
