Abstract Construction and demolition wastes (CDW) are a concern in urban areas, addition, it is well understood that soft soils inappropriate for paving designs. Therefore, this paper presents an alternative solution combining CDW silty soil, aiming to overcome the soil drawbacks by repeated loadings. For purpose, laboratory study was developed, comprising both resilient modulus (M R ) unconfin...

Soil properties play a crucial role in understanding the mechanisms of erosion and consequently developing appropriate mitigation strategies. The aim this study is to determine elastic parameters soil an erosion-prone area using Multichannel Analysis Surface Wave (MASW) method geophysical exploration. active MASW was adopted for study. Data were acquired 24-channel ABEM Terralock MATK-6 seismog...

A novel materials-selection procedure has been developed and implemented in software. The procedure makes use of Materials Selection Charts: a new way of displaying material property data; and performance indices: combinations of material properties which govern performance. Optimisation methods are employed for simultaneous selection of both material and shape. INTRODUCTION The performance of ...

The electric cone penetration test (CPT) has been in use for over 40 years and is growing in popularity in North America. This paper provides some recent updates on the interpretation of some key geotechnical parameters in an effort to develop a more unified approach. Extensive use is made of the normalized soil behaviour type (SBTn) chart based on normalized cone resistance (Qt) and normalized...

Class F fly ash cannot be used alone in soil stabilization applications as it is not selfcementing. An activator such as Portland cement or lime must be added to produce cementitious products often called pozzolan stabilized mixtures. The developed mixture must possess adequate strength and durability, should be easily compacted, and most importantly should be economical and environmentally fri...

The settlement behavior is a common problem on the railway structure that can be optimized by applying cement-treated soil as ground restoration. However, application of high cement mixing content needs proper estimation achieved adjusting element testing. strain measurement devices estimate deformation characteristics, such secant modulus, Poisson ratio, and shear modulus describe stiffness so...

We develop a theory of sheaves and cohomology on the category proper modulus pairs. This complements [KMSY21], where non-proper pairs has been developed.
