In that case, the base material for artificial turf goes on top of your existing dirt, serving as a barrier between your turf and the dirt underneath. Suppose you’re eyeing a traditional installation to replace existing landscaping. Your Base Material for Artificial Turf: The Details The Best Base for Artificial Turf Depends on Your Needs.What Else Do I Need Along With a Base Material for Artificial Turf?.Option 1: Crushed Miscellaneous Base/Class II Road Base.Your Base Material for Artificial Turf: The Details. ![]() “Microstructural analysis of recycled aggregate concrete produced from two-stage mixing approach.” Cement and Concrete Research, Vol. “Evaluation of reclaimed asphalt pavement aggregate in road base and sub-base.” Transportation Research Board, No. Taha, Ramzi, G.alal Ali, Basma, A., and Al-Tuck, O. “Study on recycled asphalt concrete for use in surface course in airport pavement.” Resources, Conservation and Recycling, Vol. Investigation of recycled asphalt pavement (RAP) mixture, Final Report, Minnesota Department of Transportation, MN/RC-2002-15. “Feasible use of recycled concrete aggregates and crushed clay brick as unbound road sub-base.” Construction and Building Materials, Vol. ![]() “Application of construction and building debris as base and sub-base material in rigid pavement.” Journal of Transportation Engineering, Vol. “Effect of recycled concrete aggregate on properties of asphalt concrete.” Resources, Conservation and Recycling, Vol. “Correlation analysis between rut resistance and deformation strength for Superpave mixtures.” Journal of Korean Society of Road Engineers, Vol. Performance of recycled hot mix asphalt mixtures, National Center for Asphalt Technology Report 95-1. “Framework for developing a static strength test for measuring deformation resistance of asphalt concrete mixtures.” Construction and Building Materials, Vol. “Laboratory characterization of recycled concrete for use as pavement base material.” Transportation Research Board, No. By evaluating the Marshall test properties of each mixture, it is also concluded that the dynamic loading in the Marshall test compaction method possibly causes friction in the RCA of the asphalt mixtures and, therefore, leads to an underestimation of the engineering properties of HMA with RCA.īrandon, J. As a result of this study, it is observed that the study asphalt mixtures with RCA (Mixes II and III) show good performance compared to the asphalt mixture with natural aggregate only (Mix I) in terms of indirect tensile strength ratio, deformation strength, rut depth, and IDT strength, whereas Mix IV, which consists of coarse and fine RCA, does not exhibit good performance. In addition, asphalt mixtures with RCA, whose binder contents were determined from the Superpave mix design method, were utilized and evaluated against Marshall design criteria in order to effectively reflect both field specifications and field compaction conditions in South Korea. For this verification, the Indirect Tensile (IDT) strength test, Kim test, wheel tracking test, and tensile strength ratio test accompanied by fundamental material property tests were performed on asphalt mixtures with four types of aggregate blends. ![]() In this research, the performance of HMA mixtures with RCA is quantitatively evaluated using various tests to verify the applicability of RCA as aggregate for HMA material. In many cases, these properties of RCA that lead to poor engineering qualities are the major reasons that RCA is not recommended as aggregate for Hot Mix Asphalt (HMA). Recycled Concrete Aggregate (RCA) is different from natural aggregate because of RCA’s cement paste and contaminants that cause low density and high porosity.
