Development of technology for obtaining asphalt concrete mixture using oil sludge as an additive [PDF]

E3S Web of Conferences
Oil sludge is similar in composition to the composition of bitumen, which is one of the important components of asphalt concrete mixture. Therefore, oil waste can be used in the production of asphalt concrete, both as an organic binder to strengthen ...

Investigation of 6PPD-Quinone in Rubberized Asphalt Concrete Mixtures

ACS Environmental Au, 2023
N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD)-quinone (6PPD-Q), a transformation byproduct of 6PPD used in tires as an antiozonant and antioxidant, was recently discovered as the chemical primarily responsible for the acute lethal toxicity of urban storm runoff to coho salmon. The asphalt concrete (AC) surface layer is the primary medium to

Asphalt concrete mixture, design and performance

, 1994
Tests conducted following the mix design stage, are unable to assess the rutting potential of asphalt concrete pavements. They range from moving a rubber tire on a slab and monitoring the rut depth to large-scale field tests using accelerated loading facilities.

Resilient Behavior of Modified Asphalt Concrete Mixture [PDF]

American Journal of Traffic and Transportation Engineering, 2018
Asphalt concrete pavement is designed to exhibit elastic behavior under loading at cold weather condition and a combination of elastic, plastic and viscous behavior at hot weather condition. Distress of the pavement usually starts with initiation of micro cracking due to load repetition, while such cracks can heal by themselves in slow process under ...
