International Roughness Index and a New Solution for Its Calculation
(American Society of Civil Engineers, 2018)The international roughness index (IRI) has been one of most widely used indicators for characterizing road roughness. However, there are some issues such as the key description of IRI spread over two large reports, no ... -
Colored Petri Net Simulation Model to Allocate Motor Graders for Earthmoving Operations
(American Society of Civil Engineers, 2018)Earthmoving processes are extremely important for road construction because of the high costs involved. Discrete-event simulation has been used as a decision-support tool for earthworks planning and operation in the last ... -
Experimental Simulation and Quantification of Migration of Subgrade Soil into Subbase under Rigid Pavement Using Model Mobile Load Simulator
(American Society of Civil Engineers, 2018)Rigid pavement structure typically consists of a surface layer (concrete), underlying granular layers (subbase and/or base), and a compacted subgrade soil layer. Because the subgrade is saturated during wet seasons, cyclic ... -
Simplified Closed-Form Procedure for Network-Level Determination of Pavement Layer Moduli from Falling Weight Deflectometer Data
(American Society of Civil Engineers, 2018)Accurate estimation of the layer moduli for an existing pavement system is a key element for making an effective decision on pavement rehabilitation. Backcalculation is one of the most widely used processes for analyzing ... -
Fuzzy Logic–Based Life-Cycle Cost Analysis of Road Pavements
(American Society of Civil Engineers, 2018)Life-cycle cost analysis (LCCA) is a decision-making mechanism that can be used to determine the best road pavement option. It is prevalently applied by transport authorities. However, the effect of uncertainty that stems ... -
Decision-Making Tool for Incorporating Cradle-to-Gate Sustainability Measures into Pavement Design
(American Society of Civil Engineers, 2018)Pavements consume large amounts of energy, materials, and a significant portion of maintenance funds, which cause a substantial strain on the environment and the economy. Hence, a sound framework for designing and constructing ... -
Simulation of Impact of Water-Film Spray on Visibility
(American Society of Civil Engineers, 2018)On rainy days, large rain particles in the air block and scatter the light so that visibility on roads decreases. However, it is conventionally ignored that the spray caused by high-speed vehicles with the existence of ... -

Optimizing Budgets for Managing Statewide County Paved Roads
(American Society of Civil Engineers, 2018)This paper develops an optimization model of budget needs for improving county paved roads in Wyoming. Both decision makers and county road engineers need to establish budget needs and allocate resources effectively. In ... -
Use of Steel Fiber–Reinforced Rubberized Concrete for Roadway Intersections in Cold Regions: Alaska
(American Society of Civil Engineers, 2018)In cold regions, many challenges are faced when using portland cement concrete (PCC), but with the inclusion of new technologies such as steel fibers and crumb rubber, efficient construction is possible. Steel fiber–reinforced ... -
Application of a Machine Learning Method to Evaluate Road Roughness from Connected Vehicles
(American Society of Civil Engineers, 2018)Response-type methods have been widely used for road roughness evaluation. However, an important limitation is that they require calibration to account for response and speed variations among instrumented vehicles. The ... -
Concrete Pavement Blowup Considering Generalized Boundary Conditions
(American Society of Civil Engineers, 2018)An analytical expression for static stability of a rectangular slab with two simply supported and two elastically restrained edges is presented. The linear elastic isotropic slab can represent a rigid pavement resting on ... -
Impact of Local Calibration Using Sustainable Materials for Rigid Pavement Analysis and Design
(American Society of Civil Engineers, 2018)A catalog of locally appropriate Mechanistic-Empirical Pavement Design Guide (M-EPDG) inputs was developed for North Carolina Department of Transportation (NCDOT) rigid pavements using 18 concrete mixtures produced with ... -
Development of a Volumetric Mix Design Protocol for Dense-Graded Cold Mix Asphalt
(American Society of Civil Engineers, 2018)Cold mix asphalt (CMA) provides a number of benefits that make it a promising alternative to hot mix asphalt and warm mix asphalt, including reduction in both heating energy and emissions, as well as longer working time ... -
Approximating an Analytic Solution for the Optimal Design of Asphalt Pavement: Limited Example
(American Society of Civil Engineers, 2018)This paper considers how the expected service life of asphalt pavement can be modeled taking into consideration different climates, different amounts of traffic, and an opportunity for optimal design, namely, the choice ... -
Quantification of Aggregate Embedment in Chip Seals Using Image Processing
(American Society of Civil Engineers, 2018)Chip seals are among the most popular preventive maintenance techniques implemented by many Departments of Transportation (DOTs), county road departments, and cities. The deteriorated pavement surface is sprayed with an ... -
Analysis of the Influence of Materials and Construction Practices on Slurry Seal Performance Using LTPP Data
(American Society of Civil Engineers, 2018)This study investigated the influence of materials and construction practices on the performance of slurry seal treatments that were applied in the long-term pavement performance (LTPP) program. The concept of equivalent ... -
Pavement Integrity Assessed by Leaky Surface Waves with Wave Group Interpretation
(American Society of Civil Engineers, 2018)The structural integrity of pavement is the key to keeping motorists safe and comfortable while driving on roads. Failure to maintain structural integrity of pavement results in traffic disruptions and even causes havoc ... -
Fatigue and Thermal Cracking Analysis of Asphalt Mixtures Using Continuum-Damage and Cohesive-Zone Models
(American Society of Civil Engineers, 2018)Cracking in asphalt pavements has continued to cause prominent pavement distress. This study evaluated fatigue and thermal cracking performance for nine asphalt mixtures using three approaches: simplified viscoelastic ... -
