Hydrothermal recovery of asphalt from asphalt concrete

Construction and Building Materials, 2016
Abstract The use of non-organic, environmentally friendly solvents such as water is essential for recovery of useful products from construction sector wastes, including asphalt concrete. Here, hydrothermal water was utilized to recover asphalt from asphalt concrete in a batch-type reactor (autoclave) of internal volume 500 mL.

Study on thermal properties of steel slag asphalt concrete for snow-melting pavement

, 2020
The utilization of steel slag in asphalt concrete can improve the thermal conductivity of steel slag asphalt concrete. The thermal conductivity of asphalt concrete largely affects the surface temperature distribution of asphalt pavement, which in turn ...

Bitumen and asphalt concrete modified by nanometer-sized particles: Basic concepts, the state of the art and future perspectives of the nanoscale approach.

Advances in Colloid and Interface Science, 2020
Asphalt concretes are biphasic systems, with a predominant phase (c.a. 93-96% w/w) made by the macro-meter sized inorganic aggregates hold together by small amounts of a viscoelastic binding bitumen (c.a. 5%).

A two-dimensional random aggregate structure generation method: Determining effective thermo-mechanical properties of asphalt concrete

, 2020
This study presents a 2D random aggregate structure generation algorithm for asphalt concrete. It involves two steps: first, the “convex-concave surface method” is proposed to generate random aggregate particles; second, the “double background grid ...

Mechanical response analysis of asphalt pavement on curved concrete bridge deck using a mesostructure-based multi-scale method

Construction and Building Materials, 2021
Curved concrete bridges are an important infrastructure form, which meet the needs of modern transportation. Due to their relatively sophisticated geometries, asphalt pavements on the bridge decks are typically subjected to more severe loadings.
