Evaluating The Field Performance of Asphalt Mixtures

2021-6-26  One of these advanced technologies is the Simple Performance Tester (SPT), which evaluates asphalt mixtures to determine their response to permanent deformation (rutting) and fatigue cracking. FHWA is supporting NCHRP's research by evaluating how well the SPT works in a field laboratory environment.

Field performance evaluation of asphalt mixtures ...

2018-7-10  Other laboratory studies have observed better fatigue performance in asphalt mixtures containing up to 30% RAP , while poorer fatigue resistance is found in asphalt mixtures containing 50% RAP . Despite numerous laboratory studies have been conducted on including a significant amount of RAP into the production of asphalt mixtures, however, few has done to verify the findings in laboratory with the field observed performance.

Evaluating the rutting resistance of asphalt mixtures ...

2014-6-30  Therefore, it is important to accurately evaluate the rutting resistance of asphalt mixtures in the design process of pavement structure and material. Various laboratory tests have been developed to characterize the rutting resistance of asphalt mixtures. Generally, they fall into two categories: empirical and fundamental.
