The disposal of waste face masks (FM) caused by COVID-19 has become an increasingly severe problem. In order to alleviate this issue, paper proposes approach adding mask as modifiers asphalt. Extensive performance tests evaluated the feasibility FM in asphalt binders, including rotational viscosity and rheological behaviors at different temperatures, aging performance, separation tendency, modification mechanism. Based on this, road FM-modified mixtures were also investigated. results showed that increased viscosity, high-temperature anticreep whereas it had a negative effect stress change sensitivity, low-temperature storage stability binder. linear amplitude sweep test results, incorporation contributed material integrity load resistance capacity binder, was not conducive its antideformation performance. According Fourier transform infrared spectroscopy fluorescence images, process with chemical composition polypropylene mainly physical blend, 5% best compatibility addition could improve Marshall stability, rutting resistance, cracking moisture susceptibility AC-13 mixture. mixture met specific requirements. experiment provide new way deal recycling.

This study evaluates the quality and mechanical performance of various shapes reclaimed concrete aggregates (RCAs), including elongated, cone-shaped, angular, ordinary mix, in comparison to fresh (FAs). The RCAs are treated with fly ash-based geopolymer, effects percentages geopolymer content on geotechnical properties modified investigated. finds that angular shape an RCA exhibits more strength than other shapes, use significantly improves characteristics by up 10%. research also shows geopolymer-treated subbase layer flexible pavements can lead a reduction required thickness base layer, resulting significant cost savings curtailment CO2 emission compared FAs.

Improvement in subgrade soil has always been an area of concern for highway and geotechnical engineers. Weak results a greater thickness the pavement layer, which increases cost construction. It further leads to large deformations, turn cause continuous deterioration paved surface. To solve this problem, various engineering solutions improvement mechanisms were previously proposed. This study was designed investigate stabilization weak with nylon synthetic fiber (NSF) compromising combination. Previously, some investigations used lower content higher length, whereas others length content. However, investigation uniquely stabilize consideration appropriate (10 mm 20 mm) (0.5%, 1%, 1.5%, 2.5%). The properties soil, effect NSF on aspect ratios, optimum critical ratio investigated laboratory. fibers compaction, CBR values, swell values also studied. Laboratory modified compaction tests showed that maximum dry density (MDD) increased increment content, moisture (OMC) remained constant. soaked natural 1.80% 8.95%, respectively. Due reinforcement, percentage increase value at is 265.3, 310.0, 282.8, 342.2 ratios 33.33, 66.67, 25, 50, respectively, reference soil. Also, decrease swelling 34.7, 52.75, 43.55, 36.9, Moreover, by keeping diameter constant decreases observed increasing reinforced substantial 1.5% 50 (length = mm, 0.4 mm).

Soil vapor extraction (SVE) technology has strong potential value in the decontamination of soils dominated by volatile contaminants. In this paper, order to evaluate detail influence main factors on efficiency SVE, L9(34) orthogonal tests and response surface analysis were carried out using a self-developed one-dimensional SVE system model. A first-order kinetic reaction model was also employed analyze relationship between pollutant concentration time. The thermal unit with scale consistent soil column indoor test simulated COMSOL simulation software. obtained results indicate that most important affecting performance are time, temperature, contaminant concentration, while flow rate is not significant. can be used predict half-life concentrations. Combined desirability function, optimal conditions for removal ethylbenzene from were: time 180 min, temperature 20 °C, 6000 mL/min, 2%. developed numerical model, 3D-SVE, nicely simulates laboratory findings. These provide ideas improve SVE.
