Effect of Tire Parameters on Pavement Damage and Load‐Equivalency Factors
Publisher: American Society of Civil Engineers
Abstract: The effects of tire pressure, tire type, axle load, and axle configuration are investigated under actual truck loading and highway speed on instrumented test sections. The various tire types are tested against the 11R22.5 ...
Development of Dynamic Fatigue Failure Criterion
Publisher: American Society of Civil Engineers
Abstract: When a truck wheel moves on the road, stress pulses develop within the pavement layers. These pulses are primarily functions of load magnitude, tire pressure, and vehicle speed. In this study, dynamic analysis is used to ...
Evaluation of Low-Temperature Properties of HMA Mixtures
Publisher: American Society of Civil Engineers
Abstract: The deterioration of flexible pavements due to low-temperature cracking is a significant and costly problem in the state of Nevada. The Nevada Department of Transportation initiated several research efforts aimed at exploring ...
Dynamic Pavement‐Strain Histories from Moving Traffic Load
Publisher: American Society of Civil Engineers
Abstract: This paper presents the formulation and the application of a continuum‐based finite‐layer approach to evaluate dynamic pavement strains under moving traffic load. The dynamic material properties (complex shear modulus and ...
Impact of Antistrip Additives on the Long-Term Aging Rheological Properties of Asphalt Binders
Publisher: American Society of Civil Engineers
Abstract: Hydrated lime and liquid antistrip agents have long been used as an asphalt additive to improve resistance to moisture damage. Previous studies have shown that the addition of hydrated lime to asphalt binders reduced the ...
Impact of Antistrip Additives on Pavement Performance Using Mechanistic-Empirical Pavement Design Guide
Publisher: American Society of Civil Engineers
Abstract: A comprehensive study was conducted to evaluate the impact of liquid and lime additives on the pavement performance of asphalt mixtures from five different sources around the United States. Three types of mixtures were ...
Evaluation of Polymer-Modified Asphalt Concrete Mixtures
Publisher: American Society of Civil Engineers
Abstract: Since the mid-1980s, polymer-modified asphalt concrete mixtures have been widely used to minimize rutting failures of flexible pavements. This research investigates the permanent deformation behavior of unmodified asphalt ...
Fatigue Characteristics of Superpave and Hveem Mixtures
Publisher: American Society of Civil Engineers
Abstract: A study was conducted to evaluate the fatigue characteristics of hot mix asphalt (HMA) mixtures designed using the Superpave volumetric method and Nevada’s Hveem method. Fatigue characteristics were evaluated using the ...
Pavement Strain from Moving Dynamic 3D Load Distribution
Publisher: American Society of Civil Engineers
Abstract: This paper presents the formulation and the application of a continuum-based finite-layer approach to evaluate pavement strain response under actual traffic loading. The model incorporates important pavement response ...
Performance of Full‐Scale Pavements Under Accelerated Loading
Publisher: American Society of Civil Engineers
Abstract: This paper describes the performance of two pavement sections at the FHWA's Pavement Testing Facility. The sections are classified as thin and thick flexible pavements and were designed according to the new AASHTO design ...
