Abstract

The major distresses in asphalt pavements are rutting, fatigue, and adhesion loss (moisture susceptibility). In this research study, two substitution fillers (Cement and Lime) were used with two different aggregate quarries (based on minerals composition) to evaluate the relatively most beneficial combination of both fillers as well as an aggregate quarry to enhance the performance life of asphalt pavements, especially in under-developed countries. Four basic tests, (Asphalt Pavement Analyzer, Four Points Bending Beam, Dynamic Modulus, and Rolling Bottle Test) that used for the most desired properties of any asphalt pavement, were utilized to access the performance properties of modified asphalt mixture. Based on all laboratory test results this research study concludes that replacement of aggregate filler with hydrated lime and cement has a beneficial effect on asphalt mix performance and to save investment by using raw material. Substitution filler improves the high-temperature rut performance and intermediate temperature fatigue performance of asphaltic concrete mixture up to 25% to that of the conventional mixture. At the same time, substitution filler has more beneficial to improve 70% adhesion properties to that of the conventional mixture.

Abstract

This research investigates the interplay of genotypes and year on yield and related traits in bread wheat. Two hundred wheat genotypes, including commercial varieties and landraces were evaluated at Hazara University, Pakistan during 2020-2021 and 2021-2022 crop seasons. Analysis of variance revealed significant differences among genotypes, years, and genotype × year interactions (G × Y) for traits like tillers per square meter, grain weight per spike, grains per spike, 1000-grain weight, biological yield, and grain yield. Descriptive statistics outlined the range and mean values for these traits over two years. Noteworthy genotypes, such as Milat-2011 (maximum tillers), Khirman (heaviest grain weight per spike), NIFA-Aman (most grains per spike), and Pakistan-13 (heaviest 1000-grain weight), showed superior performance. Tandojam-83 led in biological yield, and Punjab-1 excelled in grain yield. Principal Component Analysis (PCA) identified biological yield and grain yield as major contributors to genetic variation. Cluster analysis revealed significant variability, grouping genotypes like Punjab-1, Tandojam-83, Punjab-96, Ufaq, and others into distinct clusters. Significant positive correlations were found between tillers per square meter with both biological yield and grain yield. This study offers valuable insights into G × Y interactions and genetic diversity, aiding wheat breeding programs aimed at improving yield and stability.
