Bio-Based Rice Husk Ash as an Eco-Friendly Filler in Pre-Vulcanized Latex Asphalt Concrete Wearing Course Mixtures

Journal of Natural Fibers
This study investigates rice husk ash (RHA) as a filler substitute in pre-vulcanized latex asphalt mixtures. RHA replaced conventional rock ash at 50% and 100% substitution levels, while latex was added at 7% and 9% by weight.

Artificial neural network based modelling of the Marshall Stability of asphalt concrete

Expert Systems with Applications, 2011
Research highlight? Marshall Stability (MS) of asphalt concrete under varying temperature and exposure times was modelled by using artificial neural network. In order to investigate the MS based on physical properties, exposure time and environment temperature, exposure times of 1.5, 3, 4.5 and 6 h and temperatures of 30oC, 40oC and 50oC were selected.

The Marshall-Lerner Condition: Stability of an Equilibrium or a System?

Asia and the Global Economy
This article examines the Marshall-Lerner (ML) condition from a broader perspective. Mundell (1968) regarded ML as the stability condition of the equilibrium, but not of the system. The violation of the ML condition by Japan's estimates is interpreted as a possible symptom of a negative exchange rate depreciation spiral in Thorbecke (2022).

Predicting Marshall Stability and Flow Parameters in Asphalt Pavements Using Explainable Machine-Learning Models

Transportation Engineering
The traditional method for determining the Marshall stability (MS) and Marshall flow (MF) of asphalt pavements is laborious, time consuming, and costly. This study aims to predict these parameters using explainable machine-learning techniques. A comprehensive database comprising 721 hot mix asphalt (HMA) data points was established, including ...

Analysis of Marshall's Stability of Hot Mixtures with Machine Learning

Brilliant Engineering
Road transport is the most widely used transport network globally and in Turkey. Every year, asphalt mix designs are prepared for the deterioration or reconstruction of road pavements. Since asphalt mixture designs affect the mechanical and physical properties of roads, they also directly affect their performance. For this purpose, Marshall design, one
