RISAggregate Physical Properties Affecting Modulus and Deformation Characteristics of Unsurfaced Pavements
Publisher: American Society of Civil Engineers
Abstract: This paper presents findings from a recently completed research study at the University of Illinois aimed at investigating the effects of aggregate type and quality on mechanistic pavement response and rutting performance ...
Evaluating Alkali-Silica Reactivity of Aggregates Using the New Miniature Concrete Prism Test and Other Standard Test Methods
Publisher: ASCE
Abstract: The alkali-silica reaction (ASR) has been recognized as a major distress in concrete for nearly a century. In the US, ASR is a major cause of the deterioration of highway concrete structures (i.e., bridges and pavements). ...
Summary Resilient Modulus Prediction Model for Unbound Coarse Materials
Publisher: ASCE
Abstract: The resilient modulus of base and subbase layers is a needed parameter in mechanistic pavement analysis and design. The standard test procedure for measuring the resilient modulus is complex and the setup may not be available ...
Polyurethane Grout Injection as Remedial Measure to Reduce Differential Heave in Pavement Sections Constructed over Expansive Soils
Publisher: ASCE
Abstract: Flexible pavement sections constructed over expansive soil deposits often undergo significant damage due to volume changes in the underlying soil strata. When expansive soil deposits are confined to shallow depths, ...
