ABSTRACT
Roads for traffic, working platforms for wind turbines and outdoor sport accommodations such as artificial turf installations, all require sufficient resistance to permanent deformation of the structure throughout their service life. This specifically applies to areas with poor subgrade. Sub-base stabilization or reinforcement by geosynthetic grids or cellular modules may help to increase the load carrying capacity, to prolong service life but also to reduce mineral aggregate required for construction subsequently leading to a cut in construction costs and CO2-emissions. The paper addresses the new harmonized Dutch design procedure for road base reinforcement of roads with block paving where resistance to rutting appears to be the prevailing design criterion. The paper also addresses testing of the innovative product TenCate Accorder®. Results of laboratory testing and the use of the test results in the design of a reinforced road base and a subsurface of an artificial turf accommodation are presented.
