Polyphosphric acid (PPA) modified asphalt binders were produced in the laboratory using one base asphalt and four levels of PPA contents (0.6%,1.0%,1.5% and 2.0% by
Traffic loading is usually characterized by means of the number of Equivalent Single Axle Loads (ESALs) or by means of the axle load distributions (load spectra
The major objective of this research was to discuss the effects of loading rate on the flexural-tension properties and uniaxial compressive strength of micro-su
