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...

the present study was an attempt to investigate varieties of cloze test and c-test as measures of reading comprehension ability. it aimed at comparing the performances of subjects on different cloze and c-test forms constructed from the same passage. to this end, five versions of cloze test and two versions of c-test were developed by applying different deletion techniques and deletion rates, a...

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...

Styrene-butadiene-styrene (SBS) is currently the most widely used asphalt modifier. However, high-SBS-concentration high-viscosity modified asphalts (HVMA) are characterized by poor flow and storage instability. To make up for lack of performance traditional SBS-HVMA, a nano-based composite with excellent was developed. Since carbon nanotubes (CNTs) nanomaterials, they prone to agglomeration wh...

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...
