Comparison of flow number, dynamic modulus, and repeated load tests for evaluation of HMA permanent deformation

Use of the MSCR test to characterize the asphalt binder properties relative to HMA rutting performance – A laboratory study

“…However, the test may not be applicable to SMA mixes. Some studies have reported that the unconfined RLPD test, at high test temperatures, was not appropriate to sufficiently measure and capture the permanent deformation properties of SMA mixes that have high stone content, forming a gap-graded stone structure with high viscosity bituminous mastic, which is different from conventional dense-graded mixes [2,13,14]. Therefore, the RLPD test was performed only on Type C mixes in this study.…”

Rubber modified binders as an alternative to cellulose fiber – SBS polymers in Stone Matrix Asphalt

“…Initially designed to provide a mixture that offered maximum resistance to studded tyre wear [2], the use nowadays of the SMA mixtures has spread widely because it provides high resistance to plastic deformation under heavy traffic loads with high tyre pressure [3].…”

Indirect Tensile Test as a Simple Method for Rut Resistance Evaluation of Asphalt Concrete

“…Al-Khatebb et al [1] found that the FN test results showed better fitting to the expected trend than the dynamic creep test results. On the other hand Zhang et al [10] conducted a comparative evaluation of the FN, DM and RLPD tests, found that the FN Index, in contrast to the classical FN (cycles) parameter, exhibited a better correlation with results of both the DM and RLPD tests. Xu et al [8] carried out the partial triaxial test (PTT), and stated that a strong correlation was found between the strain slope value at the second stage in the PTT and the total rut depth in the WTT.…”
