Continuous groundwater quality monitoring is crucial for ensuring safe drinking and irrigation by mitigating risks from geochemical contaminants through appropriate treatment methods. Therefore, the primary objective of this study was to assess suitability collected Lucknow, India, both irrigation. Forty samples were different sites within area evaluate quality. Various parameters such as pH, turbidity, total dissolved solids (TDS), chlorides (Cl−), alkalinity, hardness, sulphate (SO42−),...

The main objective of the present investigation is to assess usefulness agricultural and industrial waste as a soil admixture, focused improve engineering properties make it capable lower layer road construction. Present describes behavioral aspect soils mixed with materials viz. fly ash (FA), rice husk (RHA) & bagasse (BA) material straw (RSA) load bearing capacity soil. Clayey has been considered using four different types stabilizer FA, BA, RHA RSA ranging from 5 35% by weight physical...

Fatigue sensitivity of four different asphalt binders and three mixes was evaluated in the study. Binders were subjected to Linear Amplitude Sweep (LAS) test at temperatures 10, 20, 30°C. Four-point beam bending (4PBBT) conducted on a temperature 20°C for strain amplitudes varying from 200 1000 microstrains. Tests like retained Marshall Stability indirect tensile strength (ITS) also carried out judge mix performance. Experimental studies demonstrated that elastomeric modified binder gave...

Poor affinity of asphalt toward mortar paste has been testified as the primary reason for reducing reclaimed pavement (RAP)–inclusive concrete properties, although effect dust present in RAP aggregates due to extraction using demolition techniques not investigated so far. The paper discusses different methods on mechanical properties fine aggregates. Also, incorporation fresh, mechanical, and durability investigated. It was found that substitution level natural (NA) by (0, 25, 50, 75, 100%)...

The main objective of the study was to characterize fatigue and rutting behavior polymer-modified asphalt binders, by determining effect temperature stress/strain levels on results multiple stress creep recovery (MSCR) linear amplitude sweep (LAS) test. modifiers included styrene butadiene (SBS) ethylene vinyl acetate (EVA). These effects were quantified means nonrecoverable compliance (Jnr) percent (R) values in MSCR, power law model Parameters A α LAS also compared with conventional VG 10...

The advanced traveler information system (ATIS) is a type of intelligent transportation application areas that implements emerging computer, communication, and technologies to provide vital the users regarding traffic regulation, route location guidance, hazardous situations safety advisory, warning messages. ATIS requires large amount data for processing, analysis, storage effective dissemination users. A geographical (GIS) allows be effectively processed, stored, analyzed, logically...

In the road construction sector, world is facing a major problem of scarcity conventional materials. On other hand, there are some materials, which lying as waste. Some waste products, e.g., fly ash can be utilized an additive to this study, reinforced was tried subbase material. The influence various parameters planned investigated through static and dynamic load tests semifield tests. It observe effect polypropylene fiber reinforcement on such unconfined compressive strength, modulus...

Various rutting susceptibility parameters for unmodified and modified bitumen were studied at three different temperatures of 40, 50, 60°C. Wheel rut testing was also conducted on bituminous mixes The test used to evaluate the performance correlated with mix results, best suited method identified. It found that ranking binders respect remained unaltered irrespective any method. Statistically, multiple stress creep recovery (MSCR) correlate more accurately wheel results as compared other...

In the present study, adverse effect of dust on properties concrete containing 75% fine reclaimed asphalt pavement (RAP) (75F) (obtained using an uncontrolled milling technique) is minimized by higher doses superplasticizers (SP) in combination with silica fume (SF), flyash (FA), and bagasse ash (BG). It was found that 75F mix requires at least double amount SP to achieve recommended slump value. Moreover, improvement fresh state enhance hardened significantly. Inclusion considered mineral...

The present study aims at studying ageing characteristics of conventional bitumen, polymer modified bitumen (PMB) and warm mix asphalt (WMA) by using FTIR. Results obtained FTIR spectrum were quantified calculating different indices finally based on these index the binders for short- long-term calculated. showed increased amount complex high molecular weight components binders. PMB was found to have greater resistance than In case WMA, results be inconclusive, requiring further investigation.

In this study, the feasibility of coarse (RC) and fine (RF) reclaimed asphalt pavement (RAP) inclusive concrete for sulfuric acid hydrochloric environments is assessed. Moreover, efficacy mineral admixtures such as silica fume (SF), fly ash (FA) bagasse (BG) in 100% RC mix was investigated. Three sets conditions were selected so to simulate worst field situation resistance completely saturated dried state effect both acids on residual compressive strength hydration process. The mixes found...

Increase in traffic, new axle configurations and high temperature, demands the use of modified binders for resisting stresses induced. The primary goal modifier is to increase stiffness at temperature while maintaining its flexibility lower temperatures. It tends effective visco-elastic response binder. Among different modifiers, polymers have been very promising improving properties Ethylene Vinyl Acetate (EVA) a plastomer, obtained by co-polymerization ethylene vinyl acetate. Depending on...

Abstract Development of modified asphalt materials to improve the overall performance pavements has been focus several research efforts made over past few decades. Use discarded waste plastic construction was one steps taken in this direction. Using road will not only bring out significant saving material costs but also help towards tackling problems disposal such materials, which tend be hazardous as much they can cause pollution both air and water. The dynamic shear rheometer is used for...
