Abstract

Various types of hot asphalt (mixture of mineral aggregate and bituminous binder–bituminous mixture) are used in the construction of flexible pavements, depending on the project requirements, to ensure optimal use of the asphalt. From all available asphalts, each country uses a combination of those that are considered to be the most appropriate to their climatic and traffic conditions. Asphalts are characterized by the particle size distribution of the aggregate mixture. Theoretically, there are unlimited types of asphalts, namely, from asphalts consisting only of almost single-sized coarse aggregates to mixtures consisting only of fine aggregates (sand). The goal of bitumen laboratory testing is to describe its qualities, determine its appropriateness, and forecast its behaviour over the course of the pavement's service life. All technological, mechanical, rheological, physical, and chemical attributes are included in the term typical properties. The purpose of the report is to collect aggregate samples from Malakand, Dara Adam Khel, Basai, and Karak quarries and to compare its Physical and Mechanical Properties with Margalla aggregate by using the Marshall Method of design for asphalt concrete.

Abstract

Following thorough soil investigation, the designs for the foundations and other structures are made. The foundations and structures are more reliable and safer when the right soil is used. In this study, cement-coated Polypropylene (PP) sheets were employed to strengthen the soil, enhancing its shear strength and other characteristics. Two (2) soil samples were taken to compare the average outcomes and minimize error. Before using PP sheets for soil reinforcement, various index and strength parameters, such as breaking tensile strength, elastic modulus, and breaking and fusion points, among others, were examined. Properties like liquid and plastic limit, specific gravity, Maximum Dry Density (MDD), and Optimum Moisture Content (OMC) were examined as discussed. Reinforcement of 0%, 0.05%, 0.15%, and 0.25% were applied and tested against shear strength evaluation with the help of a direct shear test. An increase in strength is observed in soil samples 1 and 2, i.e., 1.27, 2.25, 2.27 and 1.28, 1.42, 1.65, and 1.79 in kg/cm2, respectively. Similarly, unconfined compression strength was observed to increase from 0.0692 MPA to 0.0942 MPA, which is 11.68% and 35.94% increment in soil samples 1 and 2 at 0% and 0.05% reinforcement, respectively.

Abstract

The purpose of this study is to provide Pakistani citizens with Ultra-High-Performance Concrete utilizing locally available resources. In an experimental study, steel fibres are combined with silica fume and rice husk ash when superplasticizers are present. Several different tests were done using completely different volumes and different amounts of ingredients from local supplies and steel fibres to investigate ultra-high-performance concrete. Results show that ultra-high-performance concrete can be produced using locally accessible material. There are differences in the compressive and flexural strengths of the Ultra High-Performance concrete. Every outcome is pleasing. Scanning electron microscopy and X-ray diffraction tests were also used to assess the ultra-high-performance concrete's microstructural analysis. The transition zone between fine aggregates and the cement paste is enhanced by the use of silica, according to X-ray diffraction and scanning electron microscopy test results. Dense packing is one of the main factors influencing concrete strength, and it is achieved by using a low water to-cement ratio. This observation is gained from Scanning Electron Microscopy and X-ray diffraction tests. The steel fibers in ultra-high-performance concrete inhibited the propagation of cracks in the matrix.
