RISApplication of Microcalorimeter to Characterize Adhesion between Asphalt Binders and Aggregates
Publisher: American Society of Civil Engineers
Abstract: Adhesion between asphalt binder and aggregate in a dry state as well as in the presence of water is critical to the performance and durability of asphalt mixtures. According to the literature, distress mechanisms in asphalt ...
Characterization of Aggregate Surface Energy Using the Universal Sorption Device
Publisher: American Society of Civil Engineers
Abstract: Moisture damage in asphalt concrete pavements is a major cause for high maintenance costs of state and federal highways. Moisture damage in asphalt concrete is largely due to loss of adhesion between bitumen and aggregate, ...
Addressing Sulfate-Induced Heave in Lime Treated Soils
Publisher: American Society of Civil Engineers
Abstract: Civil engineers are at times required to stabilize sulfate-bearing clay soils with calcium-based stabilizers. Deleterious heaving in these stabilized soils may result over time. This paper addresses critical questions ...
Review of Stabilization of Clays and Expansive Soils in Pavements and Lightly Loaded Structures—History, Practice, and Future
Publisher: American Society of Civil Engineers
Abstract: Expansive clay soils—those that change significantly in volume with changes in water content—are the cause of distortions to structures that cost taxpayers several billion dollars annually in the United States. Much has ...
Unique Effects of Hydrated Lime Filler on the Performance-Related Properties of Asphalt Cements: Physical and Chemical Interactions Revisited
Publisher: American Society of Civil Engineers
Abstract: Hydrated lime is evaluated as a filler in bitumen and is compared to similarly sized filler comprised of calcium carbonate, limestone. Extensive laboratory testing is considered, including rheological testing of mastics ...
Static Creep and Repeated Load as Rutting Performance Tests for Airport HMA Mix Design
Publisher: American Society of Civil Engineers
Abstract: A performance test, rather than an empirical test, to evaluate rutting susceptibility is needed to accompany current volumetric property requirements of airport hot mix asphalt (HMA) designed using a superpave gyratory ...
Tensile Fracture and Fatigue of Cement‐Stabilized Soil
Publisher: American Society of Civil Engineers
Abstract: Portland cement‐stabilized soil is widely used as a base material for roads, airfields, and similar structures. Cracking in this material is studied using fracture mechanics concepts. Fracture toughness in the form of the ...
One‐Dimensional Constitutive Modeling of Asphalt Concrete
Publisher: American Society of Civil Engineers
Abstract: This paper presents a mechanistic approach to constitutive modeling of asphalt concrete under complicated repetitive loading conditions with rest periods. From an extensive literature review, two mechanisms are identified ...
Rutting Predictions in Flexible Airfield Pavements Using a Newly Modified Drucker–Prager Combined Hardening Model with Progressively Evolving Yield Surface
Publisher: American Society of Civil Engineers
Abstract: Granular materials subjected to compressive cyclic loading of constant amplitude when modeled using an isotropic hardening, elastoplastic Drucker-Prager (DP) model do not accumulate significant plastic strain beyond the ...
Enhanced Performance of Polyelectrolyte-Stabilized Sandy Soils under Wetting and Drying Cycles
Publisher: American Society of Civil Engineers
Abstract: This study addresses the utility of polyelectrolytes, i.e., cationic poly(diallyldimethylammonium chloride) (PDADMAC) and anionic polystyrene sulfonate (PSS), as additives to improve properties of the polymer-stabilized ...
