“…This test result again demonstrates that an optimum packing of particles was achieved at FI = 20. Vivanco et al (32) recently reported that the highest cone tip resistance was achieved at a similar FI value of 20 in multiple PANDA Ò penetrometer tests on various ballast materials tested with different FI values; these findings are in accordance with the box test results in this study.…”

The progressive degradation of railway ballast over time increases the degree of ballast fouling and poses significant drainability concerns leading to frequent maintenance activities. To avoid such issues, an effective and continuous characterization of the physical properties of the ballast layer is deemed necessary. This paper introduces the combined use of a bender element (BE) piezoelectric field sensor and a PANDA® dynamic cone penetrometer for periodic evaluations of ballast condition over the traffic use. To simulate various levels of ballast degradation, box tests were conducted using a dolomitic ballast material compacted in a laboratory-sized testbed with fouling indices ranging from zero to 39%. BE sensor pairs were embedded in the ballast layer to calculate the small strain modulus behavior of the ballast assessed through shear wave velocity measurements under different confinement conditions. Strength profiles of the ballast at different fouling levels were also measured using the PANDA® penetrometer. Experimental findings from both test methods indicate the existence of a dense state of ballast linked to a certain fouling index that maximized stiffness and strength characteristics of the tested ballast in dry condition. Accordingly, the potential use of BE field sensors embedded within in-service ballasted track coupled with periodic penetration testing can be a viable approach to evaluate ballast layer degradation. Various void packing conditions associated with ballast fouling levels can be linked to important ballast layer modulus and strength behavior. Further, such smart sensing of ballasted track behavior can provide long-term performance monitoring solutions for ballast cleaning and maintenance scheduling.

This work presents the results of tests carried out as part of the study of the influence of ballast fouling materials and compaction states on the dynamic cone resistance. It is a complement for a previous study on the statistical analysis of the influence of ballast fouling on penetrometer and geoendoscope data [1].As a result of this previous work, a particular behaviour of the average cone resistance was highlighted. The cone resistance (qd) initially increases with Fouling Index, highlighting the mechanical resistance to penetration improvement of the ballasted layer. Then, when the ballast is fouled, this mechanical resistance decreases. However, the tests cases This behaviour was highlighted for specimens without compaction differences.The present study exposes results obtained from similar test specimens compacted in two new distinct sates. For the same range of Fouling Index (FI), this study confirms the previously highlighted behavior for more compacted test cases with only sandy fouling material.
