  • Ballasted Track - an overview ScienceDirect Topics

    David Thompson, in Railway Noise and Vibration, 2009. 11.5.3 Ballast mats. For ballasted track, it is possible to introduce ballast mats under the ballast in order to increase the vibration isolation.Such mats are often used for track in tunnels – see Chapter 13.A typical stiffness per unit area is of the order of 30 MN/m 3, which gives a stiffness per sleeper end of around 20 MN/m.

    Li et al. found that track deterioration was faster and quickly becomes more critical for ballasted tracks built on stiff subgrades (e.g. concrete bridge decks, tunnels and crossings) where the damping capacity of the track cannot withstand the heavy cyclic loads. In heavy haul freight services, ballast aggregates subject to high stresses and ...

  • Track Buckling Research Volpe National Transportation ...

    Problem DefinitionProblem SeverityResearch to DateTrack buckling is formation of large lateral misalignments in continuous welded rail (CWR) track, often resulting in catastrophic derailments. Both curved and tangent tracks are susceptible to buckling with typical curve buckle amplitudes ranging from 6\"-14\" and tangent buckles from 12\"-28\". Buckles are typically caused by a combination of three major factors: high compressive forces, weakened track conditions, and vehicle loads (t在volpe.dot.gov上查看更多信息

    The idea with ballasted track is that water is not allowed to accumulate in the ballast if it has good drainage. The idea with unballasted track is that the concrete redirects the water so that the ground immediately below it stays dry, achieving the same result.

    Keep in mind for appearance, if you weather it, that will change/improve the appearance as well. I like the real rock ballast (choose your brand) because of it's density and ease of use - it's going to stay put when soaking with adhesive better than the nut shell based Woodland Scenics, which more easily floats or washes away.
