Journal ArticleDOI
Prediction of thin asphalt concrete overlay thickness and density using nonlinear optimization of GPR data
TL;DR: In this article, a gradient descent based nonlinear optimization approach was developed to analyze ground-penetration radar (GPR) signals collected from thin asphalt concrete (AC) overlays to estimate their thickness and density.
Journal ArticleDOI
Development of a Pressurized Blister Test for Interface Characterization of Aggregate Highly Polymerized Bituminous Materials
TL;DR: In this paper, the authors describe a recently developed adhesion test procedure that predicts interface bonding based on a fundamental property of the interface, interfacial fracture energy (IFE), and discuss the adhesion of several hotpoured bituminous sealants to aluminum, limestone, quartzite, and granite.
Journal ArticleDOI
In Situ Measurements of Secondary Road Flexible Pavement Response to Vehicular Loading
Imad L. Al-Qadi,Salman A. Bhutta +1 more
TL;DR: In this paper, a secondary road pavement section was instrumented with strain gauges, pressure cells, piezoelectric sensors, thermocouples, and moisture sensors, and the instrumentation response to controlled and normal vehicular loading indicated that geosynthetic stabilization provided significant improvement.
Journal ArticleDOI
Tecnico accelerated ageing (TEAGE) – a new laboratory approach for bituminous mixture ageing simulation
TL;DR: In this paper, the available methods for accelerated ageing simulation in laboratory of compacted bituminous mixtures are often not representative of the ageing mechanisms experienced in the field, and the objective of the objective is to simulate the ageing mechanism experienced by the human body.
Journal ArticleDOI
Investigation of viscoelastic fracture fields in asphalt mixtures using digital image correlation
TL;DR: In this paper, the authors studied the fracture behavior of asphalt mixtures, a heterogeneous mix of hard aggregates (usually in the form of crushed quarried rock) with a petroleum-based asphalt binder, used in paving applications.
