The effect of aggregate micro and macro texture on pavement skid resistance of Malaysia road network
The skid resistance of the surface of the highway is controlled by its microtexture and macrotexture. Microtexture refers to irregularities in the surfaces of the stone particles (fine-scale texture) that affect adhesion and make the stone particles feel smooth or rough to the touch. Macrotexture...

| 总结: | The skid resistance of the surface of the highway is controlled by its microtexture
and macrotexture. Microtexture refers to irregularities in the surfaces of the stone particles
(fine-scale texture) that affect adhesion and make the stone particles feel smooth or rough to
the touch. Macrotexture refers to the larger irregularities in the road surface (coarse-scale
texture) that effect hysteresis and associated with voids between stone particles. This paper
evaluates the effect of aggregate microtexture, macrotexture and influence of pavement surface
under dry and wet condition to skid resistance. Three (3) different types of pavement surface
were selected to obtain friction value on Continuously Reinforced Concrete Pavement (CRCP),
Hot Mixture Asphalt pavement (HMA), and Ralumac Micro-Asphalt. In addition, skid
resistance value was calculated from British Pendulum Tester and texture depth by using sand
patch method. From the field test conducted and statistical analyses of the data, there were
strong relationship between microtexture, macrotexture and types of surface pavement
subjected to different dry and wet conditions |
