High Performance, Highly Modified Asphalt: The Next ...

2021-4-29  What Is High Performance/Highly Modified Asphalt? Highly Modified Asphalt (often called HiMA™ or HPG) is exactly what it says, an asphalt binder with 2-3 X the amount of SBS polymer used to produce grades such as PG76-22 The resulting binder contains a dense polymer network that significantly improves mixture performance

Evaluation of a highly-modified asphalt binder for field ...

2018-5-20  Note that both sections 3% SBS and 6% SBS were similar in performance probably because of the limited time period of the data collected. If data were collected over a longer period, the effect of the highly-modified asphalt on long-term performance might be observed.

In-field aging process of high content SBS modified ...

2018-9-1  Abstract. Highly modified asphalt (>6.0 wt% styrene butadiene styrene copolymer, SBS) has been extensively used for extending the durability of porous asphalt (PA) pavement. In depth knowledge of the in-field aging of different PA layers is needed because the natural aging of PA possessing around 20% voids content severely affects its properties.

High performance bituminous sub-ballast for improving

2021-5-4  Materials. Two different binders were studied for the creation of the high-performance bituminous sub-ballast layer: a conventional B50/70 bitumen (CB) was used as a reference, having been commonly used in previous asphalt railway tests [9, 20]; and a modified, low-penetration bitumen containing rubber from out-of-use tires (MB).The latter bitumen is a commercial product, specially

Oklahoma Anticipates I-40 Performance Gain with HiMA

Oklahoma Department of Transportation (ODOT) officials have high hopes for a mill-and-overlay of I-40 just west of Oklahoma City that incorporates highly modified asphalt (HiMA) pavement. ODOT is using HiMA on I-40 in Caddo County in the first commercial application of this new technology. Work on this project began with traffic crossover placements in February []

Analysis of MSCR test results for asphalt binders with ...

2021-4-9  The multiple stress creep recovery (MSCR) test has been regarded by many as the best available test method to evaluate the high-temperature performance of asphalt binders. However, recent studies have shown that the 9-s recovery time may not allow a full recovery of viscoelastic strain for some modified asphalt binders. In that case, some potential viscoelastic recovery is mistakenly reported ...

Preparation and Properties of SBS-g-GOs-Modified

Cong et al. used benzoyl peroxide as an initiator to graft maleic anhydride onto SBS, along with enhanced high temperature performance and the storage stability of the modified asphalt. Chemically, the polybutadiene segment of SBS contains a large number of C=C bonds, which can be divided into three structures: 1,2 C=C, and cis and trans 1,4 C=C.
