Pavement system includes the surface, subgrade, base and subbase. ACEGrid® BG and ACEGrid® GF can be applied as reinforced material in asphalt overlay. This application can disperse cyclic loading of vehicle and lower reflective cracking occurrence due to temperature difference to extend useful life of pavement.
placed in base or subbase these two granular layers can enhance the bearing capacity of pavement, lower rut occurrence, decrease thickness of granular layer and extend useful life of pavement.
If foundation of pavement is classified as soft soil, base and subbase granular layers might be sinking into subgrade due to long-term vehicle vibration. ACETex® is suggested to separate two different layers which can prevent granular layer from pollution by subgrade soil and exert its bearing capacity.
