Asphalt Thermal Regeneration Equipment Mix Design Of Concrete

Study on Cooling Effect and Pavement Performance of Thermal ...

To reduce the temperature of asphalt pavement and improve the antirutting performance of asphalt mixture, a thermal-resistant asphalt mixture (TRAM) was produced, in which a certain proportion of mineral aggregate was replaced by ceramic (CE) or floating beads (FB) featuring low thermal conductivity. Firstly, a parallel plate test was developed to test the thermal conductivity of asphalt ...

Development of an IDEAL cracking test for asphalt mix design ...

Development of an IDEAL cracking test for asphalt mix design and QC/QA. The focus in recent years has been to make asphalt mixes more affordable, and this has led to the increased use of recycled materials and binder modifications. Consequently, one often-heard complaint is that the recent mixes are more susceptible to cracking.
