Laboratory Evaluation of the Residue of Rubber-Modified Emulsified Asphalt
TL;DR: In this paper, the residue characteristics of rubber-modified emulsified asphalt and the effect of using crumb rubber to modify the asphalt binder were quantified using Fourier transform infrared spectroscopy (FTIR) test.
Journal ArticleDOI
Effect of laboratory-produced cellulose nanofiber as an additive on performance of asphalt binders and mixes
TL;DR: In this paper, the authors applied a scalable process for laboratory production of Cellulose Nanofibers (CNF) and evaluated feasibility of using the produced CNF as a sustainable plant-based asphalt additive to improve the mechanical properties and durability of asphalt pavements.
Kansas Department of Transportation 2014 chip seal manual : [technical summary].
Dean M. Testa,Mustaque Hossain +1 more
TL;DR: The 2014 Chip Seal Manual as discussed by the authors provides guidelines, background and general information for the design, construction, and inspection of chip seal, a very effective thin surface treatment process used by maintenance managers to preserve existing asphalt pavements.
Journal ArticleDOI
Investigation of rheological properties of asphalt emulsions
TL;DR: In this paper, a preshear protocol was introduced and four kinds of asphalt emulsions were tested base on prehear and a modified palierne model was used to predict storage and loss modulus of asphalt.

The colloidal structure of bitumen: Consequences on the rheology and on the mechanisms of bitumen modification
TL;DR: A general picture of bitumen structure is shown to emerge and it shows that a simple solvation parameter allows quantifying the effect of the asphaltenes on the rheological properties ofbitumen.
Journal ArticleDOI
Comparison by Fourier transform infrared (FTIR) spectroscopy of different ageing techniques: application to road bitumens
TL;DR: In this paper, the authors compared a direct and continued methodological approach of bitumen oxidation process (adapted IR cell), a road ageing, along with two ageing conventional tests: the Rolling Thin Film Oven Test (RTFOT) and the Pressure Ageing Vessel (PAV).

A Review of the Fundamentals of Asphalt Oxidation: Chemical, Physicochemical, Physical Property, and Durability Relationships
TL;DR: In this paper, a summary of current physicochemical understanding of the chemistry, kinetics, and mechanisms of asphalt oxidation and its influence on asphalt durability is presented, focusing on how the component fractions of asphalt behave under oxidation, including the effects of the mineral aggregate and metals contained in asphalts.
Journal ArticleDOI
Study on properties of recycled tire rubber modified asphalt mixtures using dry process
TL;DR: In this paper, the properties of recycled tire rubber modified asphalt mixtures using dry process were studied in laboratory, and the rubber content has a significant effect on the performance of resistance to permanent deformation at high temperature and cracking at low temperature.

Measuring the Effect of Moisture on Asphalt–Aggregate Bond with the Bitumen Bond Strength Test
TL;DR: In this article, the feasibility of the newly developed bitumen bond strength (BBS) test for moisture damage characterization was investigated and an experimental matrix that included various binders, modifications, and aggregates to account for the chemical and physical conditions in the aggregate-asphalt interface was completed.
