National Center for Asphalt Technology

Asphalt pavements have been known as America's most recycled product. As asphalt plants use more reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) in the process of producing asphalt mixtures, there is concern that mixtures with high percentages of these recycled materials may be more susceptible to cracking, as recycled binders are aged and stiffer than asphalt.

The Use of Vegetable Oil As a Rejuvenator for Asphalt Mixtures

Figure 2: Fatigue performance of the aged and rejuvenated asphalt mixtures. 2.2. Binder Testing The extent of rejuvenation can be a major uncertainty and cause for concern during hot mix recycling of asphalt. Assumptions are made that all materials are thoroughly mixed and that the blended binder meets requirements such as

1. Introduction - Hindawi

The quality and viscosity of REOB-rejuvenated asphalt, RA5-rejuvenated asphalt, and base asphalt were measured after extended TFOT (ageing times for 5 h, 10 h, 15 h, 20 h, and 25 h), and the low-temperature performance of three aged asphalts was evaluated by bending beam rheological tests.

Evaluation of Waste Engine Oil-Rejuvenated Asphalt

The use of large proportions of reclaimed asphalt pavement is necessary to meet the increasing demand for road construction materials in a sustainable way. One of the challenges of using a greater percentage of reclaimed asphalt pavement (>30%) is the greater stiffness of mixes incorporating it. While this stiffness problem is usually resolved by using different commercial rejuvenators, there

Preparation and Performance Characterization of Warm-Mix

Reclaimed asphalt pavement (RAP) material is generally under a large amount of aged asphalt coated on the surface of the aggregates, which often limits its (RAP) wide application. Bioasphalt is a renewable material with constituent components that are comparable to regular petroleum asphalt and has the potential to rejuvenate the performance of the aged asphalt in RAP materials.

1.1 This test method covers the determination of the flexural-creep stiffness or compliance and m-value of asphalt binders by means of a bending beam rheometer. It is applicable to material having flexural-creep stiffness values in the range of 20 MPa to 1 GPa (creep compliance values in the range of 50 nPa -1 to 1 nPa -1) and can be used with unaged material or with materials aged using
