RISTransitioning from AASHTO T283 to the Simple Performance Test Using Moisture Conditioning
Publisher: American Society of Civil Engineers
Abstract: The current method of determining the moisture susceptibility of asphalt concrete mixtures is American Association of State Highway and Transportation Officials (AASHTO) T283. AASHTO T283 is based on the Marshall mix design ...
Investigation of Isosorbide Distillation Bottoms as a Bio-Based Warm-Mix Additive
Publisher: American Society of Civil Engineers
Abstract: Biorefineries are increasing in number and size and include products based on food, energy, and chemicals. Depending on size and targeted products, biorefineries produce distillation bottoms with surfactant characteristics ...
Preliminary Dynamic Modulus Criteria of HMA for Field Rutting of Asphalt Pavements: Michigan’s Experience
Publisher: American Society of Civil Engineers
Abstract: This paper presents a comparative study of laboratory results of both dynamic modulus testing and field rutting performances of hot-mix asphalt (HMA) in the state of Michigan. Fourteen field-produced mixtures at various ...
Integration of Moisture Sensitivity Testing with Gyratory Mix Design and Mechanistic-Empirical Pavement Design
Publisher: American Society of Civil Engineers
Abstract: Moisture damage is one of the major problems that can be faced by a pavement during its design life. It can tremendously reduce a pavement’s strength and consequently its life. The test predominately specified to evaluate ...

Investigation of In-Place Asphalt Film Thickness and Performance of Hot-Mix Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: This research work investigates approaches for computing the average asphalt film thickness in asphalt mixtures and examines whether the in-place asphalt film thickness has a rational relationship with the performance of ...
Factors Study in Low-Temperature Fracture Resistance of Asphalt Concrete
Publisher: American Society of Civil Engineers
Abstract: An investigation of various factors that can affect the fracture resistance of asphalt mixtures at low temperatures was conducted. The fracture resistance of 28 asphalt mixtures—which represent a combination of factors ...
Effects of Using Accurate Climatic Conditions for Mechanistic-Empirical Pavement Design
Publisher: American Society of Civil Engineers
Abstract: The implementation of the new mechanistic-empirical design guide has led to the need for more accurate inputs. One of the most important inputs that affect the performance of the pavement materials is the climatic data. ...
Assessment of Composite Pavement Performance by Survival Analysis
Publisher: American Society of Civil Engineers
Abstract: The main objective of this paper is to identify the most appropriate rehabilitation method for composite pavements and to evaluate the influence of different factors for the reflective crack development in composite pavement ...
