[FY2023 Problem B No.15] Which of the following descriptions regarding test methods used for quality control of roadbeds and subgrades is incorrect? (1) The modified CBR test is conducted for the ...

1. It consists of a series of layers with the highest quality materials at or near the surface of pavement. It consists of one layer Portland cement concrete slab or relatively high flexural strength.

A newly patented geopolymer technology is being deployed to repair and strengthen rail infrastructure. While the initial focus is on the transition zone, supplier Geobear sees wider potential too. One ...

In order to study the morphology and chemical properties of geopolymer-stabilized soil, selected soil samples were subjected to SEM and EDS testing. The SEM and EDS tests were performed using a Zeiss ...

Modulus of subgrade reaction or coefficient of subgrade reaction is the reaction pressure sustained by the soil sample under a rigid plate of standard diameter per unit settlement measured at a ...

Abstract: As we approach further in time, need for all the commodities increase these commodities may include food grains, vegetables, poultry and meat requirements, fruits etc. all these commodities ...

ABSTRACT: The modulus of subgrade reaction ks depends on several factors such as the size and shape of the foundation as well as the embedment depth of the foundation. The present study is an ...

The decrease in the subgrade modulus immersed in rainwater can significantly increase the fracture risk of a cement concrete pavement plate. The aim of this study was to develop a meshless finite ...

Loratorial tests with pervious concrete comprised porosity and hydraulic conductivity as well as mechanical parameters as compressive, indirect tensile and bending strengths besides assessing its ...
