The improved pavement structure of road with reinforced graded macadam base by geocells was proposed, in orderto compare with the conventional permeable concrete pavement structure in the mechanical performance, and to analyze thefeasibility of the improved permeable pavement structure applied to the urban type III road, three different improved pavementstructures were designed considering the height of the geocell and the welding distance. The mechanical performance tests ofthe three types of improved pavement structures and one conventional pavement structure were carried out respectively. Thesurface settlements, base stresses and geocell strains of the pavement structures under different load conditions were comparedand analyzed. The results show that the improved pavement structure of reinforced graded macadam base by geocells can fullymeet the requirements of type III road for its bearing capacity and deformation limit; the geocell with 200 mm height and 445mm welding distance has more obvious reinforcement effect on macadam base than the other two kinds of geocells, and canreduce the center settlement and concentrated stress more effectively.

Geogrid plays an important role in geotechnical, transportation and water conservancy projects. Geogrid and soil are regarded as a kind of general, composite material for which the representative cell is selected reasonably. A numerical model to evaluate equivalent elastic constitutive parameters is developed via a multi-scale asymptotic analysis for periodic structures-based homogenizing technology, and the effects of properties and sizes of component materials on the macro-equivalent elastic constitutive parameters can be taken into account conveniently. The work presented here may provide valuable reference for the further application of geogrid and help in the promotion of the forecast of the geogrid and soil macro-equivalent creep constitutive properties.
