This study compares the rutting and cracking resistance fatigue parameters of crumb rubber (CR) modified warm asphalt binders, which were determined by viscoelastic continuum damage (VECD) theory. The effect combination CR modification Sasobit, a mix additive, was investigated. Performance + Sasobit compound compared with styrene-butadiene-styrene (SBS) modification. Newly developed rheological...

<p class="abstract">There are numerous instruments available to assess pigmentation in terms of color, melanin, and other factors, but there is no standardized or validated tool a person's glow radiance. The MSCR- radiance index (G&R)-composite scale was created with the help bio-physics background includes five important factors. intended provide an objective, scientific assessme...

Abstract In order to solve the problem of high-value utilization coal-to-oil residual direct coal liquefaction asphalt, it is compounded with SBS and aromatic oil modify matrix 9 compounding schemes are designed using orthogonal experimental methods. Dynamic frequency sweep tests DSR a simplified Carreau equation model fitted complex viscosity obtain its zero shear viscosity; creep recovery rat...

The adoption of warm mix asphalt (WMA) technologies is well accepted due to its promising environmental benefits, however, their long-term field performance not understood. This study focused on the rutting resistance WMA and companion hot (HMA) based 83 samples collected from 28 projects across United States covering four climate zones, quantified impacts for various as compared HMA. Field cor...

Asphalt pavements are prone to aging in construction and during service, which can affect the properties of asphalt. The behaviors high content crumb rubber modified asphalt (HCRMA) were investigated this paper. binders aged laboratory performances before after tested using attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) test, temperature sweep (TS) frequency test...

For promoting modifying application of sprayed polyurea (SPUA) in asphalt pavement materials, the effects materials on high-temperature and fatigue performance binders were investigated from different aspects. First, optimal preparation parameters sprayed-polyurea-modified (SPMAs) determined by designing an orthogonal test. Then, properties with contents characterized rheological testing method...

This investigation evaluates aging characteristics and photocatalytic performance of asphalt cements modified with titanium dioxide (TiO2) at different percentages (3, 5, 7% by weight the binder). Conventional were used to manufacture specimens hot mix (HMA) compacted in laboratory a Gyratory Compactor subjected environmental conditioning for 6, 12, or 18 months which they exposed temperature c...

Mycothiol (MSH; AcCys-GlcN-Ins) is the major thiol found in Actinobacteria and has many of the functions of glutathione, which is the dominant thiol in other bacteria and eukaryotes but is absent in Actinobacteria. MSH functions as a protected reserve of cysteine and in the detoxification of alkylating agents, reactive oxygen and nitrogen species, and antibiotics. MSH also acts as a thiol buffe...

In recent years, Reclaimed Asphalt Pavement (RAP) has become very popular in pavement construction due to its benefits the economy and environment. The present study investigates feasibility of employing Waste Cooking Oil (WCO) Engine (WEO) as rejuvenators blended with reusable asphalt binder through physical rheological properties at high intermediate temperatures. Examined conventional WCO-an...
