Abstract: Development of pavement concrete compressive strength, flexural strength, and splitting tensile strength as a function of time is discussed. Eighteen sets of post‐1985 exerimental data from academic and industrial sources ...

Abstract: Air-entrained high performance concrete (HPC) crossties or ties (alternatively called sleepers outside of North America) have been observed to suffer structural and material degradation at the rail seat area (RSA), including ...

Abstract: Foam concrete is a porous cement-based material that could accommodate a high-volume particle addition at the mid- to high-density range (0.8 to 1.6  g/cm3). However, with low-density foam concrete (0.4 to 0.8  g/cm3), ...

Abstract: Monotonic load tests have been conducted on plain and fiber-reinforced concrete slabs on ground to monitor the effect of fiber type and dosage on the strength properties of concrete slabs. The results revealed that simple ...

Abstract: Rail seat deterioration (RSD) continues to be identified as one of the primary factors limiting concrete crosstie service life in North America. RSD refers to the degradation of material at the contact interface between ...
