  • Epoxy Asphalt Frequently Asked Questions | ChemCo Systems

    How does Epoxy Asphalt concrete differ from conventional asphalt concrete? Epoxy Asphalt is a concrete made with a binder that, unlike conventional asphalt, does not become brittle at low temperature and does not melt at high temperature. Epoxy Asphalt pavements have much higher stability, much less susceptibility to cracking, are less ...

  • Fatigue Endurance Limit for Highway and Airport Pavements ...

    The existence of a fatigue endurance limit has been postulated for a considerable time. With the increasing emphasis on extended-life hot-mix asphalt pavement, or perpetual pavement, verification of the existence of this endurance limit, a strain below which none or very little fatigue damage develops, has become a substantial consideration in the design of these new multilayered full-depth ...

  • Fatigue life and endurance limit prediction of asphalt ...

    Fatigue cracking is one of the major types of distress in asphalt mixtures and is caused by the accumulation of damage in pavement sections under repeated load applications. The fatigue endurance limit (EL) concept assumes a specific strain level, below which the damage in hot mix asphalt (HMA) is not cumulative.
